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 (!)

Hawaii Earthquake

Meanwhile, a shallow 3.0Mw earthquake struck about 62km west of Kalaoa, Hawaii.

The quake, centered at 19.825°N 156.570°W, struck at a depth of 5.6km and was timed at 02:08:02 UTC on Monday, March 31, 2014, said USGS/EHP.
