Mount St Helens discussed on News and Perspective with Tom Hutyler


News one thousand FM ninety seven seven the two hundred thirty square miles flattened by the may eighteenth nineteen eighty eruption of mount St Helens have had for decades to recover but they still show clear signs of what happened on that Sunday morning it was Ryan Harris talked to the resident expert about that recovery and about what's changed and how they watch the volcano the events of that morning started with the growing bulge on the northwest side of the mountain finally coming loose in a massive landslide which then uncorked mount Saint Helens and allowed all the hot gas and magma inside two explode out that buried the land around it and filled the total river's North Fork with mud and trees so deep but it took decades for the river to carve itself through the dirt Dr Seth Moran scientist in charge for the U. S. geological survey's cascades volcano observatory first visited in nineteen eighty eight is a UW grad student and he says eight years later the transition from forest to decimated was still sharp in the eighties and nineties you could see that on the west side as well and on the road that you drive up to get to the cold water geysers center and now the Johnson's research right there's a blast on on the west side now as you're coming into the transmissions are richer you cannot tell that you've gone into the blast on the trees the force is growing up and it's a very full forest over the last ten years certainly that continues to grow it's still very obvious when your actual storage you can very much see the landslide deposits and lahars and the creator and all those things are still laid bare but you can also see vegetation moving inward Moran says they're also able to detect the movement of elk herds with their seismometers and goats have been spotted up in mount Saint Helens crater doctor Moran tells me many of the instruments they used to monitor the mountains are in the same places but as with so many things the technology and capabilities of the seismic network have vastly improved we're working actively this summer and next summer to upgrade more so sites and get them into sort of the modern digital world we're still using and about half the sites on analog telemetry there's a combination of those familiar places that jala Justin seismologists from forty years ago we recognized today as all this is where we had things but the sides looked look a little bit different technology has dramatically improved in so many areas in the last forty years and that's over you're much more able to record the signs and symptoms that double kos producing and really detect small small scale phenomena looks very small earthquakes very small surface decorations on the order of of millimeters Moran says one volcanoes are quiet lake St Helens is right now and after the two thousand four to two thousand eight eruption they can spot gradual increases in the number of small deeper earthquakes and he says the GPS instrument spotted outward movement of about one or two centimeters over six years which he says shows there's probably some magma deep in the earth and pushing the ground away in two thousand fourteen we issued an information statement that said based on these two forms of evidence we believe that there is some small amount of new magma coming into the system that's recharging it part of the process of the volcano building towards the next Russian which is years to decades down the road is not short term warning but St Helens is still alive and that we certainly need to continue to do the monitoring even if you know the volcano goes for decades more without any interruptions and we need to make sure that the network is ready for the time that it does too because when it wakes up it would separate fast as it's shown us in nineteen eighty in two thousand four Dr Moran says the cap was blown off mount St Helens in nineteen eighty after pressure built up behind it and we're still without that cap but there's other ways of all cables can produce explosive Russians that's just you know to get a batch of Bangladesh frothy has lots of gas and it it makes it to the surface that by itself can be enough to produce an explosive eruption Moran says in the cascades mount St Helens isn't the only one to watch because of their history of large explosive eruptions he says they have an eye on glacier peak in crater lake and Wiley says Mount Rainier and mount hood haven't had large eruptions in their past they have to watch for smaller ones because with people living nearby the small eruptions can have large consequences Ryan Harris komo news at eleven fifteen AM we need to check your money news the propellants are it's a business update what is the market rebalances the Baker Hughes drilling activity survey showed the U.
