The 10 Active Volcanoes in California

This video discusses each of the 10 active volcanoes in the state of California in detail. Mount Shasta, Lassen Peak, the Salton Buttes, Clear Lake, and a series of lesser-known volcanoes are discussed. The last volcanic eruption to occur in the state was in 1917 via a vent at the summit of the Lassen Peak volcano.
