Is there a volcano off the coast of California?

Davidson Seamount is a seamount (underwater volcano) located off the coast of Central California, 80 mi (129 km) southwest of Monterey and 75 mi (121 km) west of San Simeon. At 26 mi (42 km) long and 8 mi (13 km) wide, it is one of the largest known seamounts in the world.

Is Lake Tahoe an active volcano?

The Lake Tahoe area is not currently considered to be volcanically active (it must have had an eruption in the last 10,000 years to meet that criteria). However, if magma were to return to the area, future eruptions and new lava dams would pose a flooding hazard both around the Lake Tahoe basin and beyond.

  • Does California have active volcanoes?

    Volcanoes. A volcano is an opening in the Earth’s crust that allows molten rock, gases, and debris to escape to the surface. Alaska, Hawaii, California, and Oregon have the most active volcanoes, but other states and territories have active volcanoes, too. A volcanic eruption may involve lava and other debris that can flow up to 100 mph
