Mount St. Helens Eruption
On May 18, 1980, locals in Skamania County, Washington were stunned to discover that Mount St. Helens had come active. In fact, it was a rude awakening when the volcano erupted violently and the shockwave was so powerful that it blew tress in the area down. Then again, the area had been hit by a couple of earthquakes about two months before St. Helens erupted. The earthquake’s magnitude was 5.1 on the Richter scale and triggered a massive rockslide that cost over $1 billion in damages. The volcano had also been spewing steam.
