Mount St Helens erupts on this day in History

Published by mpaulin at 12:44 pm under geology, history Edit This

A few months ago, I posted a couple of articles on the Alsaka Volcano Redoubt when it was having its small eruption and a few after effects.  This activity was small compared to the explosive power of Mount St. Helens that had a major eruption on this day in history.

 

The date, May 18, 1980, a massive volcanic eruption of Mount St. Helens in southwestern Washington devastates 210 square miles of wilderness, leaving 57 dead or missing.  The volcano had erupted periodically during the previous years, with last active period prior to the 1980 explosion, being in the years 1831 through 1857.

 

The area around the volcano is slowly starting to heal as nature takes over with new growth.  Trails are open and the visitor centers are back in business as folks travel to visit the mountain.  While the mountain has not had any recent volcanic activity, the US Forest Service and the US Geological Service constantly monitor the area for any changes with cameras, sensors, and other measuring instruments.  The image is from a monitoring camera – taken on May 18, 2009 at 11:30 AM EDT.
