Earthquake strikes New Jersey, shaking reported across state
"A rare occurrence in New Jersey early Wednesday morning an earthquake the magnitude three point one earthquake struck in east revealed on social media people said they felt it as far out of status Philadelphia New York Long Island and Westchester which U. S. Geological Survey geophysicist Robert Sanders says is likely designed curriculum with anywhere in that sixty to a hundred mile range is most likely valid for this event having been stopped the quake hit at two AM and he expects little damages be very surprising for us to see anything more than you know damage shelves or or you know picture frames falling off of windows any sort of structural damage or significant bodily injury uses is not likely not very common for a for a magnitude three point one Sanders says expects smaller after shocks the last time this part of New Jersey had a magnitude three or higher earthquake was in nineteen ninety two he says before that it was seventy nine I'm Julie Walker
Covid-19 Causes a Seismic Quiet Like No Other
"Life has been quieter lately hectic at home. Maybe but you've probably noticed less traffic fewer planes, flying overhead new research published today shows it's not just quieter above ground. Coronavirus lockdown also meant a quieting of seismic noise below ground. The world's Caroline Bieler explains when you think seismic waves, you probably think earthquakes. The tremors caused by tectonic plates, scraping against each other and releasing energy in waves through the Earth's crust, but on a much smaller scale we humans make seismic waves to. From traffic. Lane landing and taking off even lots of US gathering in a stadium. Just have a word for this one. They're called football. Quake's anyway. We mostly stopped leaving home this winter and spring a lot of that seismic noise. It stopped. What we discovered is as lockdown measured. Swear taking place in different countries around the world. That was very clear. Significant decrease seismic knows that's Raphael the plan. A researcher at the National Autonomous University of Mexico research he co authored was published in the journal Science today, and shows manmade seismic noise dropping up to half globally this spring, so that was very interesting, because it was offering us a very concrete observation of decided of people were staying home as a way to protect the job it. It also presented an opportunity for science. Usually, lots of seismic noise makes it harder for researchers to detect small earthquakes. One of the plans co-authors compared it to trying to hear your phone ring at a rock concert this spring. The background volume got turned down. We each and focus on the natural signals. Trying to detect very small is derived, couldn't be absorbed before with last mount of filtering and processing more like hearing that phone ring in a library deploy, says identifying these earthquakes when it's quiet. Quiet is going to make it easier for scientists to find them again. When all that background noise comes back, scientists across the globe have been making local observations sometimes with small seismometers in their basements since lockdown started McGill University geophysicist Yang. Djing says this study brings those observations together to paint a global picture. She wasn't involved with the research. I think this is so far. The most comprehensive Stati on the global scale I'm very impressed by the scope of the study. It's part of a relatively. Relatively new sub field called social seismology, which finds connections between seismic activity and things like economic growth. This is sort of new direction that part of says Molly, branching into so I think there is a lot of contribution that's as you might be able to make in addition to just looking at the earthquake shaking records in this case, seismologists see the vibrations were making or not, as a gauge of how faithfully we're following doctor's orders to stay close to home for the world.

Unicorns of the Sea Reveal Sound Activities
"In real life, Nar walls don't speak English. Like the one bidding farewell to will Ferrell's character in the movie. Elf instead they sound more like this. That's an audio clip recorded by scientists last summer under the icy waters of northwest, Greenland. We want to describe what animals are doing. We I better understand what sounds are telling us. If Guinea Podolsky. A geophysicist at Hokkaido University in Japan, but Alcee and his colleagues study the soundscape of glacial fjords. They're noisy places where icebergs crash into the ocean and air bubbles visit of melting ice. These yards are also home to Charles. The animals are sometimes called unicorns of the seat because of their single long spiral Tusk and they're shy, which makes them hard to study so Polski teamed up with local at hunters who snuck up on narrow walls in kayaks and captured audio. That's the sound of a Narwhal looking for food, using echo-location like a dolphin or a bat. and. That's an all closing in on its prey, which had vacuums up into its toothless mouth, so start sounding like to my ear like a chain source something wick. Since? It's so many little clique SOM- that Kennedy even. Them and this is recognized as a foraging related sound used those by other animals, for example, other dolphins or bats. They do the same trick, because when they approach the target, their prey which is phenomenal, so Arctic Greenland Halibut. The want to update their. Knowledge about the position of the target more frequently because the target is moving, and they need to suck it in and. That's why the interval is getting shorter and we even using some simple simple assumptions. A equation can know how far the animal is from the target. The whistles you heard earlier are thought to be social calls individuals communicating with other nar walls. The researchers reported these observations in the Journal of Geophysical Research. Oceans, bursts, deal sounds which we don't know what they mean. And there are several wicketless, but also says that listening to Nar walls is a first step toward understanding this mysterious wail, and how it will cope climate, change, shipping, and other human activities alter its Arctic home. They're all this things taking place right now. In the region which will affect somehow this animals, but we have no clue even about the state or the previous state of this animal. So if we want to learn what's going to happen, we better start now and I hope this is where sound monitoring can help us to learn more about this still mysterious creatures.
Ethics of Commercial and Military Space
"I'm Fraser. Cain publisher of University with me as always Dr Pamela. Gay a senior scientist for the Planetary Science Institute and the Director of Bus Hip Pamela. Hey doing I'm doing well. How are you doing fraser a once again? The weather's just getting better and better. The apocalypse has never looked so. Lovely Garden is getting out of control. Is the chief sentence. It is now in control and we've got to cut it back. There's just too many plants too much grass too much weeds. I got many weeks ahead of me at this point out in the garden. The day of the trip is trying to be upon you exactly every year. More and more people are making their way to space. Some private citizens have already gotten their astronaut wings paying for a trip to space out of their own pocket. What are the ethical implications of this as the cost of spaceflight? Come down so we've got a new series. We're going to do like at least a two part series. Maybe at most two part series home. But this week we're going to talk about private spaceflight and just what are the ethical issues with this? Next week we will talk about military spaceflight. We're GONNA talk about Space Force. Although I think if we got timing a little better we could do. The episode after Space Force COMES OUT THE NEW TV show. Oh Yeah we can pull that off. Can we may thirty first. So let's talk about today. We'll talk about space tourism. The new movie that is planned next week will look at the trade off between commercial space and scientific exploration from the ground. So issues like the iridium satellites and of space resources for economic purposes. And then we'll go to space force. Okay now we've done two episodes about space tourism to fourteen and four fifty one to cover too much ground. But I think the thing that I found very interesting was just the way you had proposed it. Which is let's deal with the commercial and the ethics of this situation and we'll sort of see where that gets US first. Let's just talk about like? How do you define private spaceflight? When the purpose is the economic benefits of the parent company and its shareholders over the advancement of science and exploration causes that benefit mankind rather than stakeholders and. I mean like one version. That could very well be space. Tourism that you've got a space tourism company that is sending people on flights and they're having fun in going to the zero g hotel and enjoying themselves or flying to the moon and printing about on the moon in that low gravity but that is really just a sub set of what private spaceflight could look like so when you think about that larger umbrella. What are some other examples of the kinds of missions? We'd be run privately. Well this is where we start looking at. And this is what triggered this for me Sending people to spaced film adventure movies rather than to do the normal peacekeeping educational and scientific endeavors that take place on the space station even space tourists up until now have pretty much been tasked with. We're going to train you like an astronaut. You're GONNA do education stuff while you're up there too. And Hey we may throw you a bone and give you a little bit of science to do right but right now. Tom Cruise is looking to partner with spacex to partner with NASA and this has been tweeted out by NASA administrator. Jim Breitenstein they're gonNA film a not mission impossible but certainly an impossible mission on the International Space Station. Yeah I can't even imagine how awful difficult that process is going to be. I think I had a chance to interview someone who took the Imax seventy millimeter imax cameras up on the space station and tried to make a documentary. They gable the gave the astronauts. They taught them how to use these cameras than they had to. Fly Up with these cameras and try to shoot what they were doing. While they're up there and then send the footage back down or it was on the space shuttle. Anyway it was tough. Because it's a great big bulky professional camera that shoots an enormous amount of film at this huge aspect ratio. And it's a real challenge and so same thing right. Does he do his own shooting? Do you send up another person. Who's who does can handle camera sound hair makeup fright to the Astros get involved so I just. The details of this are blowing my mind but I think when you when we look at just all of human existence today and we think about all the trips that human beings take the vast majority of them are private right. When you fly in an airplane you know ninety nine point nine nine. Nine percent of the airplane flights are for private purposes. You are on a trip. You are carrying cargo. You are doing this. And then every now and then some would fly the airplane to a hurricane or you know to take some aerial footage of a of a drought. And that's the scientific purposes but the vast majority into. Why wouldn't it be that into the future? This is where it starts to become a how the numbers work out. And what is the ethics of this kind of question and in the frame of reference? I'm using for this is when I was a graduate student at McDonald Observatory. We'd periodically get. Vip's coming through the telescope and no matter what we're observing for science at that moment we had to kind of put it on the back burner and yeah. We'd bang the keys that we needed to keep things more or less going in a timely fashion but we had to pay attention to these guests who might be funders who might potentially help keep our science going one more year with the money. They might give the Observatory. And this okay. We are a not for profit. Enterprise we exist thanks to the generosity of our donors thanks to our competitiveness in peer reviewed science funding opportunities and thanks to our benefit actors in the state government who give us line item budgets. We know that we exist by the grace of all of these different humans and so we have to dance like the dancing monkey when they appear to keep them happy. That is of the job that we are. All aware of and astronauts are fully aware that that is also part of their job. They are all given amounts of media-training they're given massive amounts of here are effective ways to communicate complex ideas how to work a crowd how to be this stem educator. Even though they may be training pilot an engineer a doctor a myriad of other different things geophysicist. But they're all trained to be educators in the role of astronauts and when they're on the International Space Station. They know part of their is going to be on video cons with girl scouts to Judge Science Fair from outer space to do all these different feel-good tasks that remind everyone. Hey we have astronauts so the funding keeps flowing. We know that's part of the job. But that's a few moments a few hours out of your day and what we're looking at here is filming a movie in Outer Space. We don't know how long Tom Cruise and whoever else might be on the International Space Station but what we do know is while they're up there there. It's a twenty four hour gig in a large way and so now. Instead of being there a stem professionals benefiting mankind inspiring engaging educating their crew on a movie that the movie's primary goal is to have a great storyline and earn a whole lot of profit. And so where is the ethics in having our astronauts instead of engaging people in Wasilla educate them about space having them work crew on a film

"Seattle Calgary or Juno. You might have felt it October. Twenty Eighth Two thousand twelve seven point eight magnitude earthquake struck off the coast of Canada near the archipelago of Haida Guay earthquakes. Earthquakes aren't unusual in that area. Because there's a big fault line nearby but it turned out buried in the data associated with this earthquake. was something unusual joie. We were not particularly looking for something but we were Trying to look for earthquake Evolution processes when you in fan is a professor officer at Florida State University. I am has Malla Gist. Or you can say a geophysicist in a more general term and so a couple years back when he he was looking at the data from the two thousand twelve earthquake off the coast of Canada he noticed spent before that big earthquake struck. There were records of what looked. I like smaller earthquakes nearby just migrating from north to south and by noticing that I saw I found a precursor to the earthquake creek and that was quite exciting to me and that would have been pretty cool on its own a previously unknown precursor to a big seven point eight earthquake but just to make sure it was a real thing when you looked at some data from two years before and the year after so not only to Intel thousand ten thousand thirteen. Tom And what we started to find is that such activities would would happen but only happen during wintertime. uh-huh so those smaller earthquakes in the ocean weren't a precursor to the big earthquake all because they happen before it and after it to now. You don't have to be a seismologist to know that earthquakes don't exactly know when it's wintertime. That's right that's right. Yeah earthquakes aren't seasonal right. They kind of just happen when they happen by. The weather is no sure is so that was Eureka. The Eureka moments saying while the nationality of this sussman activity obviously is quite important. What when you in some of his colleagues would later confirmed? Is that storms out in the ocean.

Oldest material on Earth discovered
"A seven billion million yes seven billion year old stardust is the oldest material ever found on earth. The Australian town of Murchison Victoria is home to fewer than one thousand people. But it's one of the most important sites in the history of astronomy and eighteen in sixty nine. A huge meteorite fell to earth breaking up in the atmosphere showering fragments of space rock south of the town decades later researchers discovered that locked inside aside. Those fragments were minuscule grains of Stardust. The oldest material ever known to reach the planet reaches his bond grains that are likely five to seven billion eighteen years old older than our solar system which formed four point six billion years ago and they got ejected and wrote around the galaxy until they landed here according to one of the geophysicist. This is one of the most exciting studies I've ever worked on at the Field Museum of Natural History. CHICAGO'S A and he is the first author on a paper bubbly grains said money in a statement. Philip Heck these are older Solomon Tears ever found and they tell us about how the stars in our galaxy so they examined forty grains of stardust. They were taken from the Murchison in meteorite three decades ago determine the age of the grains they studied isotopes of elements neon which interact with cosmic rains raise in space so Anyway cool stop. They've got some pictures. If you WANNA see some stuff that's Four point six to two seven billion years old. It's just a rock but I know that you that study rocks just love this stuff

Magnitude-4.0 Ocean Earthquake Felt Throughout Southern California
"A four point oh magnitude earthquake off the southern California coast is what I'm talking about for those who were up late for a new year's eve party and then up early for the rose parade it was a wake up call they didn't need yet at two thirteen this morning the earth moved it was centered in the ocean you're the Channel Islands and people felt in places like Glendale in Hawthorne and even Orange County one man though just shrugged it off he says it's part of life here and you know we're in California we're used to it well actually waiting for the big one and there hasn't been a big one in the LA area since nineteen ninety four Randy Baldwin as a geophysicist at the national earthquake information center he says the quake this morning took place seventeen miles off shore and it was a shallow one may be at a depth of six miles you know closer to the surface and now they're there for more shaking he points out these quakes the threes in the force are very common here and no it does not mean it is not an indication that the big one is coming although experts have long been saying that southern California is overdue for a major
Magnitude-4.0 Ocean Earthquake Felt Throughout Southern California
"Chalk it up was quite a jolt to ring in the new year and earthquake striking southern California early this morning it was centered off the coast near the Channel Islands a magnitude four point oh earthquake that hit at two thirteen AM people felt it from Santa Barbara to Orange County and even if you didn't feel it just knowing that a quake could rolled through that in itself could be a little unnerving of course something something we were of all right maybe not for this one but quakes can be pretty jarring Randy Baldwin as a geophysicist at the national earthquake information center he tells K. an axe this quake was about six miles down that's pretty shallow and that means you will feel more shaking usually the earthquake is the more attenuation that you might have on some of the surface what for those who didn't feel the jolts
Internet Cables Could Also Measure Quakes
"In addition to giant crustaceans and creepy anglerfish or fish the deep oceans hide a vital piece of technology the cables connecting almost every continent island and archipelago to the Internet. But it seems those undersea cables can be used for more than just sending. Cute Cat memes around the world. We can do a good job picking up earthquakes using offshore cables. Jonathan Ho Franklin is as an applied geophysicist at Rice University and Lawrence Berkeley National Lab. He says that fiber optic cables are like threads of glass and there are impurities built it so when you shoot lasers through the fibers. Those impurities back scattered some of the light. Right back to the laser source and we make measurements of the change in the back scatter light over time. Which gives you information on the stretch of the cable at each location. His team took advantage of a brief maintenance period when a particular cable off the coast of Monterey California was not being being used for communication. The researchers studied the slight deformations in the cable. And we're able to sense. A small earthquake pinpoint unmapped faults in the sea floor and observe zurve movements in the water column. All of which may be of interest to oceanographers. Their work is in the journal

Welcome to brain stuff from how stuff works. Hey, brain stuff, Lauren Vogel bomb here on the northern coast of the Yucatan peninsula near the town of chick. Love. Mexico is a crater about one hundred twenty miles in diameter. That's about one hundred ninety kilometers the asteroid that created this crater was about six miles. That's ten kilometers wide and hit the earth sixty five million years ago in spite of these immense, measurements, the craters hard to see even if you're standing right on its rim to get a good map. Nasa. Researchers examined it from space. Ten years before the nineteen ninety discovery of the chick fil crater, physicists, Louise, Alvarez and geologist. Walter Alvarez, a father son team proposed a theory about the impact that we know today created it. They noted increased concentrations of the element iridium in sixty five million year old clay radium is rare on earth, but it's more common in some objects from space like meteors and asteroids, according to the Alvarez theory, a massive asteroid had hit the earth blanketing the world iridium, but shower of particles wasn't the only affect of the collision the impact caused fires climate change and widespread extinctions at the same time dime stores, which until then had managed to survive for a one hundred eighty million years died out, geophysicist Doug Robertson of the university of Colorado at boulder theorizes, the impact heated earth's atmosphere dramatically causing most big dinosaurs to die with an hours this mass extinction. Definitely happened fossil evidence shows that about seventy percent of species living on earth at that time. Became extinct. The massive die off marks the border between the Cretaceous and tertiary periods of earth's history. Which are also known as the age of reptiles and the age of mammals respectively today, scientists call the extinction decay t- event after the German spellings of Cretaceous and tertiary the t- event had an enormous effect on life on earth. But what would have happened if the asteroid hadn't missed would it have led to a world where people in dinosaurs would coexist or one in which neither could live. In a world where an asteroid whizzed past earth instead of crashing down with a force of a hundred million tons of TNT life could have progressed much differently. Sixty five million years ago, some of the animals and plants that are common today. We're just getting started these include placental mammals, which are mammals that develop inside a placenta in the womb and angiosperms, which are flowering plants insects that rely on flowers, such as bees were also relatively new many of these life forms thrived after the t- event, and without that mass reptilian extinction to clear the way they may not have found ecological niches to fill in this scenario. Today's world might be full of reptiles and short on mammals, including people. But even if the asteroid hadn't hit done stores and other Cretaceous life forms might have become extinct. Anyway, some dinosaur species had started to dwindle long before the asteroid's impact. This has led many researchers to conclude that the asteroid was just one aspect of a complex story. Other global catastrophes. Massive volcanic eruptions in what is now. India most likely played a role also the earth's changing landscape as the supercontinent Panja broke up into today's continents. Probably had something to do with it too. Then there's another argument that the chip to love asteroid hit the earth too early to have caused the extinction. Researchers Gerda Keller and Marcus Harding, both conclude that the impact took place three hundred thousand years before the end of the Cretaceous period. Keller theorizes chick fil impact was one of at least three massive collisions Harding argues at the iridium layer didn't come from the web asteroid but from another event such as series of meteors burning up in the atmosphere. He bases. This theory on ROY particles objected during the impact a most of these are in an older layer of the earth than the Katie iridium layer, according to both of these points of view the absence of the club. Asteroid strike may not have had a big affect on the k t extinction earth was a warm planet for most of the time that dinosaurs lived after the end of the Cretaceous period, the world got a lot colder and experienced several ice ages. Whether dinosaurs could have survived such change in climate is debatable. It's hard to come to a definitive conclusion about what the world would look like today without the chicks love impact. But the question of whether people in dinosaurs could have coexisted is a captivating won the ideas, president in everything from the Congo legend of mock lame Obembe to King Kong to the pervading kitsch of the Flintstones. Then of course, there's the prevailing scientific theory about the origin of birds that they are in essence dinosaurs that we are coexisting with today.

But the engine running that's the sound some people have compared to the mysterious non-stop noise, which is emanating from this our home planet, we've been aware of this phenomenon for decades now, and while the source of the commotion remains unknown the scientists who study at have made an important breakthrough. They finally recorded it in the nineteenth century geologists began to suspect that the earth might be producing a constant hum one which rings out even in the absence of earthquakes and seismic events. They also reasoned that the noise must be too quiet for our human eardrums to hear the official name for this drone is permanent free oscillations until somewhat recently its existence was only theoretical a team led by seismologist Hugo Benny off did try to detect the signal in nineteen Fifty-nine, but their efforts failed because at the time science did not yet possess any instruments that were sensitive enough to pick up the hump. Theory became fact, with the advance of technology in nineteen Ninety-seven, scientists at the show us station, a Japanese research base in eastern Antarctica, a were finally able to prove that permanent free oscillate really do exist. The good news was announced a year later when the show team published their findings since then numerous other teams have observed the same noise now for the first time ever, the earth's ham has been recorded easing seismic equipment on the ocean floor. This is a big deal because every previous study, which has documented the noise did so with land based instruments these she was a hard one prize for Martha dean and her team. She's a geophysicist with the Paris institute of earth physics under her leadership, the international team reviewed data collected over an eleven month period from fifty seven seismometers stations on the floor of the Indian Ocean. And that was just the first step next. The researchers eliminated all forms of audio interference such as water currents and technical glitches from the recordings made a. Two of the stations with the deletion of this extra noise. Dean and her colleagues could finally isolate the hump they were looking for a why was it so important to record the operations with submerged seismometers as dean told us in an E mail these instruments will broaden our perspective in a way that terrestrial tools. Never could. She said ocean bottom seismometers can cover much larger areas than land based ones for the ocean covers seventy percent of our planet. She added that we can better understand the phenomena by studying the hump signal at places far from land or islands. Maybe one day. We'll even be able to pinpoint its source. You see nobody knows exactly how the HAMAs is being made a few different hypotheses have been put forth some GIO, physicists think. It's generated by the ceaseless pounding of ocean waves onto continental slopes. Others believed that it could be the product of atmosphere turbulence and global wind patterns. But if that second explanation is true, we'd expect the rumblings amplitude that. It's loudness to vary from season to season. Previous studies have claimed that this is happening yet. The new research says otherwise dean's group confirmed that the hums pitch rises and falls with its maximum volume heading frequency of four point five Mila hurts that's about ten thousand times softer than the faintest noises. Our ears contest. However, according to the team's findings the amplitude changes don't correlate with seasonality thus dean and her colleagues argue that atmosphere issues alone cannot account for the existence of these permanent free oscillations. They also think that their research could open the door for future research on the earth's interior geologists use a process called tomography to map out the inside of our world. A think of it as a large scale. MRI scan dean explains scientists invert the recordings of seismic waves to decipher the makeup of various layers and structures within the planet going forward ocean bottom seismometers like those used in her reason study. Should give tomography more data to work with? Hopefully, we'll soon have a better idea of what lies beneath our feet.

"And then you get into the issue of concepts that at one point how far back if you say to a geophysicist when was the last time that Antarctica was free of ice. It's interesting Whitley that there's not a consensus may also be being hidden. You will get if you go to Wikipedia that which I consider now to be like meat cleaver research. It is not going to give you anything that is going to be scientifically accepted. But it it's where you kind of start everything and Wikipedia is is very clumsy and ham handed and political, but you will go. Disaster. Oh, terrible. Read my own Wikipedia pitch told my God is trying to politicize and sometimes embarrass people by putting them into categories. And you can't get it changed. Even though it's your name supposedly about you. Well, when you put in the question when is the last time aunt Artika was free of ice. It is so interesting there is no consensus, but you will see these two dates given the most often thirteen million years ago or thirty three million years ago. What Lee either west fair spread there? Well, look, let's let's compare it in a fraction to something that I think makes this point really dramatically homo erectus, the famous Lucy in Africa is supposed to be no more. Than two million years old. Now, if if aunt Artika was free of ice thirteen million years ago, put two over thirteen if it was thirty three million years ago put to over thirty three million any either way. If there is been an alien presence that was building huge structures on the roundish continent that we call an article thirteen million years ago or thirty three million years ago.

"Fascinating to read this piece but the experiment was to test a bunch of things like they obviously know that a real mission to mars would be much more complicated than surviving in a dome on the side of volcano you know especially when that volcanoes in hawaii now as a side note this is not the volcano that's been erupting recently that might have made it a little bit more of a difficult experiment but they did want to see what it would do to people if they were isolated for a year and a pretty barren environment and really only able to depend on each other yeah i mean there's actually a term for that type of scenario it's called ice which stands for isolated confined and extreme but the thing that struck me was the team they symbol for this mission was incredible it really makes you think about the different types of skills you need if you send a group like this to mars for the simulation they had a pilot and a flight controller that served as their engineer there was a physician and astra biologist soil scientists they even had an architect focused on space habitats i mean talk about an inch interesting job and then there was heineke who is a geophysicist yeah it's so varied it's awesome well there's a short bit from her piece that i thought was worth reading and here's what she said she said cut off from civilization we were dependent on ourselves and on each other we had to perform any work that needed doing and fix anything that broke all we had was the material contained in the storage unit dubbed the c can the near supermarket was months away we receive news from earth electrically with a twenty minute delay that's about how long it takes for signals to travel the maximum distance of two hundred and forty million miles between the two planets to be honest it took weeks for me to realize just what i'd gotten into yeah i mean it's impossible to imagine what that would.

"Actually do your own little footprints and see if they respond absolutely need to have been some excellent studies before that have used seismic recording cici's graham bass recordings i'm played them back to the elephants are we know that the other fence respond to these vibrations and they can even discriminate in terms of who has sent that particular vocalisations so whether it was a known elephant or another that they didn't and obviously this is something that needs a lot more study intensive undestanding the sensitivity of the rents are really starting to the cat how that might change under different noise conditions for example myself from humming talked to the elephants on from that one what what about other animal besides the elephants can we use seismic to detect and talk to them possibly so this technique is going to be best suited for animals that generate large amounts of force so large land mammals it's possible that we can pick them up the research that needs to be done is obviously looking at how nonni whether we can detect them but whether we can discriminate between say antelope versus subra or looking at different behaviors so that certainly the next research project that needs a lot more data to look at that do you ever think as a geophysicist you'd be involved in tracking elephants no i mean certainly had an interest in animals of all sorts of sizes everson's being a child like many others.
