NOTE:

Once Again, the USGS or University of Utah or someone decided to change EVERYTHING THEY DO and ruin my 22-year-old website.
I can't even find where they're hiding seismograms and quake data now. I'm also unemployed and trying to fix THAT too, so this could take a while to fix.
Bear with me, it'll be back, uhhh, SOME day... in the meantime, all historical data for the Park still exists here. Have at it.

This page shows all available images for one seismometer over a five-week timespan. Pick one, then enter a date to center the report on that week. Click a date to see quakes on that date; click an image to see it full-size. --Select Seismometer-- B206: Borehole B206, Yellowstone Park, WY B208: Borehole B208, Lake, Yellowstone Park, WY B944: Borehole B944, Grant, Yellowstone Park, WY B945: Borehole B945, Yellowstone Park, WY B950: Borehole B950, Norris, Yellowstone Park, WY FLWY: Flagg Ranch, WY H17A: Grant Village, Yellowstone Park, WY LKWY: Lake, Yellowstone Park, WY MCID: Moose Creek, ID YDC: Denny Creek, ID YDD: Grant Village, YNP YEE: East Entrance, Yellowstone Park, WY YFT: Old Faithful, Yellowstone Park, WY YGC: Grayling Creek YHB: Horse Butte, ID YHH: Holmes Hill, Yellowstone Park, WY YHL: Hebgen Lake, ID YHR: Hawks Rest, Yellowstone Park, WY YJC: Joseph's Coat, Yellowstone Park, WY YLA: Lake Butte, Yellowstone Park, WY YLT: Little West Thumb, Yellowstone Park, WY YMC: Maple Creek, Yellowstone Park, WY YML: Mary Lake, Yellowstone Park, WY YMP: Mirror Lake Plateau, Yellowstone Park, WY YMR: Madison River, Yellowstone Park, WY YMS: Mt Sheridan, Yellowstone Park, WY YMV: Mammoth Vault, Yellowstone Park, WY YNE: NE Entrance, Yellowstone Park, MT YNM: Norris Museum, Yellowstone Park, WY YNR: Norris Junction, Yellowstone Park, WY YPC: Pelican Cone, Yellowstone Park, WY YPK: Parker Peak, Yellowstone Park, WY YPM: Purple Mountain, Yellowstone Park, WY YPP: Pitchstone Plateau, Yellowstone Park, WY YSB: Soda Butte, Yellowstone Park, WY YTP: The Promontory, Yellowstone Park, WY YUF: Upper Falls, Yellowstone Park, WY YWB: West Boundary, Yellowstone Park, ID Center Day: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 Current Week Back 2 Weeks Forward 2 Weeks Seismometer Details Page URL for this page
