OCTOBER 2008 Yellowstone Seismicity Summary
During the month of October 2008, 46 earthquakes were located in the Yellowstone region. The largest event was a magnitude 2.4 on October 5 at 3:12 PM MDT, located about 13 miles northeast of West Yellowstone, MT. No swarms were recorded during October.
Earthquake activity in the Yellowstone region is at relatively low background levels.
Ground Deformation Summary: Through October 2008, continuous GPS data show that much of the Yellowstone caldera continued moving upward, though at a lower rate than the past several years. The maximum measured ground uplift over the past 50 months is ~21 cm at the White Lake GPS station. An example can be found at: http://pboweb.unavco.org/shared/scripts/stations/?checkkey=WLWY&sec=timeseries_plots×eries=raw
The general uplift of the Yellowstone caldera is scientifically interesting and will continue to be monitored closely by YVO staff.

The Yellowstone Volcano Observatory (YVO) is a partnership of the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

University of Utah PRESS RELEASE
The University of Utah Seismograph Stations reports that a light earthquake of magnitude 4.10 occurred at 05:59 AM on March 25, 2008 (MDT) in Yellowstone National Park. The epicenter of the shock was located 29.8 km (18.6 mi) NE of Fishing Bridge, WY. Two earthquakes of magnitude 3.0 or greater have occurred within 25 km of the epicenter of this event since 1962. The largest of these events was a magnitude 3.53 on July 20, 1992, 6.4 km (4.0 mi) NE of Fishing Bridge, WY. No earthquakes of magnitude 4.5 or greater have occurred within 50 km of the epicenter of this event since 1962. This event has been reported felt in Pahaska Tepee, outside the east entrance to Yellowstone National Park and in southwest Montana as well as in western Wyoming.
The location of the earthquake has been analyzed by a seismologist.
Persons who felt the earthquake are encouraged to fill out a survey form on the USGS Community Felt reports web site: http://pasadena.wr.usgs.gov/shake/STORE/X13060_08/ciim_display.html.
Information on the earthquake can be viewed at the University of Utah Seismograph Stations: http://www.seis.utah.edu/.
