Earthquakes shake Mt. St. Helens

Well, Mount St. Helens shared its love this Valentine's Day with quite a remarkable shake. An earthquake of 4.3 magnitude hit Mount St. Helens this morning at 10:35 a.m. After its initial shock of 3.3, it was later upgraded to a 4.3. Several minutes later, another earthquake of magnitude 2.8 struck the same area. Over a dozen aftershocks were felt after these two earthquakes. The 4.3 earthquake will allow scientists to measure any changes in the ground. These changes will indicate whether or not there is pressure from possible rising magma.
