The U.S. Geological Survey has been monitoring several earthquakes deep underneath the earth where the very active Washington state volcano's magma is churning.The USGS has detected about 350 earthquakes under Mount St. Helens since Feb. 1. Most of the quakes are originating around 4.6 miles under the volcano's gapping crater, called a caldera, and register as magnitude 1 or lower, too small to be felt at the surface.
