Lassen Hazards Assessment Published

October 12, 2012

A hazards assessment for Lassen Volcanic Center, California, is now available for download from the USGS Publications Warehouse.

The Lassen region of the southernmost Cascade Range is an active volcanic area and will erupt in the future. At least 70 eruptions have occurred in the past 100,000 years, including 3 in the past 1,000 years, most recently in 1915. Although the annual probability of an eruption is small, the consequences of some types of eruptions could be severe. The hazards assessment and report presents a discussion of volcanic and other geologic hazards in the Lassen area and delineates hazards zones for different types of volcanic activity.
