4.8 Quake Shakes Yellowstone National Park


A swarm of earthquakes, with one registering a 4.8 magnitude, shuddered parts of Yellowstone National Park on Sunday, with smaller quakes before and after that one reported by seismologists.

All of the quakes were centered around the Norris Geyser Basin, the "most dynamic" of the park's thermal areas, according to the National Park Service.

The first temblor, measuring a 2.8 magnitude, was detected shortly after midnight MDT in the park. It was followed by a magnitude 3.0 quake at 4:36 a.m., the 4.8 quake at 6:34 a.m., and a series of quakes measuring between 2.5 and 3.3 noticed between 7:30 a.m. and 9:12 a.m. MDT.

Earthquakes, and swarms of quakes, are not uncommon in Yellowstone. In the past week at least 11 other, smaller, quakes were detected by University of Utah Seismograph Stations.
