PNSN: Rockslide may have fooled system in reporting earthquake

Pacific Northwest Seismic Network says a large rockfall at Mount Rainier may have fooled its system, in reporting a 3.2 magnitude earthquake 28 miles southeast of Enumclaw, Washington.

EATONVILLE, Wash. — Pacific Northwest Seismic Network says a large rockfall at Mount Rainier may have fooled its system, in reporting a 3.2 magnitude earthquake 28 miles southeast of Enumclaw, Washington.

In an earthquake report, a 3.2 magnitude quake was reported on Wednesday at 11:49 a.m.

KIRO 7's meteorologist Morgan Palmer says it hit on the southside of Mount Rainer at the surface.

PNSN's preliminary guess at a location puts the event on the southwest part of the upper mountain below Point Success.

Mount Rainier is an active volcano, which means earthquakes are common in the area, but this time it looks like another event may have tricked the system.

Park Rangers are investigating.

KIRO 7 will clarify this details as they are made available by PNSN.
