It is common to experience swarms of earthquakes at Mount St. Helens. While it is certainly not a sign of an impending eruption, the earthquakes are a result of an active volcanic system. Mount St. Helens is most commonly known for its major eruption in 1980, the deadliest and most economically damaging volcanic event in the history of the United States. The stratovolcano is situated just 96 miles from Seattle and 50 miles from Portland, making an eruption especially dangerous. FULL REPORT
