Volcanic Eruption May 18, 1980. Mount St. Helens, located in southwest Washington, began volcanic activity in Spring. 1980 after a dormant period of 123 years. This picture was taken May 18, 1980 one hour after the major eruption blew over 2,000 feet off the top of the 9,677 ft. mountain, causing it to fall inwards and forming a crater. The photograph is shot from the south, looking north from a distance of 20 miles. Mud flows can be seen cascading down the mountain. The cloud of volcanic particles rises up to 60,000 feet in the atmosphere and has spread over most of the United States. |
