Bison sense Earth’s movement at Yellowstone National Park
YELLOWSTONE NATIONAL PARK — The strongest earthquake since February 22, 1980 rattled Yellowstone National Park on Sunday, March 30, 2014.
On Sunday, the University of Utah Seismograph Stations reported that a light earthquake occurred at 6:34 a.m. – MDT. The epicenter of the magnitude 4.8 shock was located 4 miles north-northeast of Norris Geyser Basin in Yellowstone National Park, Wyoming.
This earthquake is part of a series of earthquakes that began in this area on Thursday, March 27. As of 8:15 am Sunday, this series has included at least 25 earthquakes in addition to the main shock, with the largest of magnitude 3.1. The magnitude 4.8 main shock was reported felt in Yellowstone National Park and in the towns of West
Yellowstone and Gardiner, Montana.
Anyone who felt the earthquake is encouraged to fill out a survey form on either the Seismograph stations web site: www.quake.utah.edu or the U.S. Geological Survey (USGS) web site: earthquake.usgs.gov.
A USGS field team is in Yellowstone and visited the area near the earthquake’s epicenter Sunday. The team looked for any surface changes that the earthquake may have caused, and for possible effects to the hydrothermal system at Norris Geyser Basin.
Based on the style and location of Sunday’s earthquake, there was no indication of additional geologic activity other than continuing seismicity.
The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity 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.
No significant damage was reported.
