Did Mount Shasta erupt recently?

Mount Shasta erupts episodically with ten or more eruptions occurring in short (500-2,000 year) time periods separated by long intervals (3,000-5,000 years) with few or no eruptions. Evidence suggests that magma most recently erupted at the surface about 3,200 years ago.

Is Mount Shasta an active volcano?

Mt. Shasta is an active volcano that has erupted at least once per 800 years for the past 10,000 years, with an increased eruption frequency of about once per 250 years over the past 750 years. The region around Mt. Shasta is susceptible to lava and pyroclastic flows, lahars (mudflows), avalanches, and earthquakes.

What would happen if Mount Shasta erupted?

Lava flows and pyroclastic flows may affect low-and flat-lying ground almost anywhere within about 20 kilometers of the summit of Mount Shasta, and mudflows may cover valley floors and other low areas as much as several tens of kilometers from the volcano.

Neenach Volcano is an extinct Miocene volcano in the Coastal Ranges of California. After formation, the volcanic field was split by a fault in the San Andreas Fault Zone, and over the last 23 million years, the two halves of the volcano have moved about 195 miles (314 kilometers) apart.

What is the most notorious volcano in the Cascade Range?

Mount Rainier has 25 major glaciers containing more than five times as much snow and ice as all the other Cascade volcanoes combined. If only a small part of this ice were melted by volcanic activity, it would yield enough water to trigger enormous lahars (debris flows and mudflows that originate on a volcano).
