Ahhh....spring. When a young man's fancy turns to thoughts of....volcano awareness. The catastrophic eruptions of Mt. St. Helens thirty two years ago are a reminder that Cascade volcaoes hold potential to disrupt our communities. Eruptions and lahars at Mt. St. Helens took the lives of 57 people and caused billions of dollars in property damage. Here's a breakdown of our five active volcano neighbors.
•Mt. Baker, located in Whatcom County erupted last in the mid-1880s. River valleys are prone to landslides and lahars. Small stream plumes near the summit are observed frequently.
•Glacier Peak, is located in Snohomish County. This volcano last erupted in the 18th or 19th century. Large explosive eruptions in the past spewed ash to the east into Montana. Lahars threaten river valleys to the west.
•Mt. Rainier, located in Pierce County, produced small eruptions in the 19th century. Numerous large landslides flowed down the volcano's flanks into river valleys over the past 6,000 years. More than 150,000 people live on lahar deposits in river valleys around the volcano.
•Mt. St. Helens, is technically located in Skamania County. It is one of the most explosive and active volcanoes in the Cascades. The eruption on May 18th, 1980, was the most destructive volcanic eruption in U.S. history.
•Mt. Adams, located in Yakima County, is referred to as the "quiet giant." Mt. Adams produces lava flows, and is also prone to large landslides and lahars in the river valleys to the south, west, and north.
