Here’s some more:
Continuous GPS Data Yellowstone
. Shows ground
Recent Ups and Downs of the Yellowstone Caldera
. USGS report. (Short
Short Interview with Dr J
. Top USGS scientist at YVO talks about current quake swarm and range of things that might happen, & what they are looking out for.
Live Internet Seismic Servers
. A selection of live seismograph feeds from the US and
around the world.
. Daily updated satellite images of the world. Clickable.
NEIC Earthquake Search Page
. Very useful page to search any selected areas for quakes, within chosen time
frame and magnitude. Easy to use.
IRIS Event Search Tool
. Another handy search tool to locate quake data for your chosen time
frame and location. Good backup if the NEIC one’s not available…or too busy!
Mt St Helen’s Seismicity
. A USGS page with an
image of the seismograph for Mt St Helens from the “big” day in 1980, with the different wave forms identified. Very
handy for comparison
with current ones from Yellowstone!
. Another image from USGS that shows the different types of waveforms (on an
actual seismograph). Worth copying and keeping for comparison with what is being seen at Yellowstone.
NSL Helicorder Webcam
. A web cam feed from Buffalo Canyon, W. Nevada, showing a helicorder
(seismograph), which updates regularly, so you can see how the trace actually happens.
USGS Report of Volcanic and Seismic Hazards in Yellowstone
. PDF document. Quite long but
very detailed. Pages 24 - 32 are especially interesting. They detail what sorts of events indicate that something major might happen.
Volcanics Pushing Yellowstone Higher
short and readable article from National Parks Traveller.com. Good images and information about the magma chamber.
Interview with Dr Bernard Chouet
. Short interview with the scientist who
discovered the importance of “long-period events” in predicting imminent volcanic eruptions.
Volcano Hell: BBC “Horizon” series
. A transcript of the program that
details Dr Chouet’s discovery and documented, real-life examples of how it has been used to predict volcanic eruptions. Ten to 15 minute read but
very interesting and relevant to what’s happening in Yellowstone.
Sniffing Out Volcanic Eruptions
. Article from CNN World in 2002 that
explains how volcanoes can produce radioactive gas prior to an eruption, and how measurements downwind can detect it. From the article:
“Polonium-210 has also been detected in fallout samples preceding the eruption of Mount St Helens in the U.S. in 1980 and El Chichon in Mexico in
1982.” Don’t know if this would help at Yellowstone but worth knowing about in case it gets mentioned.
Okay, that’ll do for now!
Edited to fix a couple of links that I messed up.
