ABSTRACT

Living with Volcanic Risk in the Cascades   [open pdf - 502KB]

"The Cascade Range of the Pacific Northwest has more than a dozen potentially active volcanoes. Cascade volcanoes tend to erupt explosively, and on average two eruptions occur per century--the most recent were at Mount St. Helens, Washington (1980--86 and 2004--8), and Lassen Peak, California (1914--17). To help protect the Pacific Northwest's rapidly expanding population, USGS scientists at the Cascades Volcano Observatory in Vancouver, Washington, monitor and assess the hazards posed by the region's volcanoes."
