SEISMIC HAZARD

Swarm of earthquakes rattle Yellowstone National Park, Wyoming
The quakes included a magnitude 4.8Mw shock, the largest shock at Yellowstone since February 22, 1980, according to Yellowstone Volcano Observatory (YVO).
The swarm, which began striking the area on March 27, also included a magnitude 3.1Mw event.
The seismicity occurred in an area of uplift that has been elevated for about 7 months, said YVO.
Elevated seismicity was also observed in the same region during a previous period of uplift between 1996 and 2003.
YVO says there is no indication of other geologic activity, i.e., a volcanic eruption, except for the continuing seismicity (!)
