On May 18, 1980- The most powerful volcanic eruption in U.S. history occurred. Located in Washington State, Mount St. Helens blew its top, destroying every living and non-living thing within six miles of the volcano. The blast was so powerful in fact, that around 1300 feet of the summit was destroyed by the eruption and the preceding landslide. A massive cloud of volcanic ash rose 80,000 feet into the air- covering eastern Washington State in a blanket of darkness. Could she erupt again? According to the U.S. Geological Survey, Mount St. Helens is still an active volcano. While volcanic activity has been relatively minor since the 1980 eruption, Mount St. Helens could explode again during our lifetimes, but another eruption with the same magnitude as the 1980 eruption is unlikely.
