A 4.3 magnitude earthquake rattled the Mount Saint Helens area on Monday, February 14, 2011. The quake occurred at 10:35 a.m. and approximately thirty aftershocks followed per reports from the U.S. Geological Survey. USGS Seismologist Seth Moran confirmed the quake occurred 6 miles north and northwest of the volcano at a depth of approximately three miles. A 2.8 magnitude quake followed two minutes later in a location one mile north of the first followed by a 2.3 magnitude quake occurring at 11:35 a.m. Seismographs also recorded 6 more quakes registering at a 1.1 magnitude through 12:20 p.m.

No damages or injuries were reported as a result of the series of earth quakes. Residents from Vancouver to Troutdale reported feeling the quake, with 700 reports flooding the USGS web site.

Mount Saint Helens is a stratovolcano in Skamania County, Washington. The volcano is located 96 miles south of Seattle, Washington, and 50 miles northeast of Portland, Oregon. No signs of volcanic activity were indicated though experts believe the stress field of the volcano may have been affected.
