Where is the Long Valley Caldera in California?
Where is the Long Valley Caldera in California?
eastern California
The Long Valley Caldera sits in eastern California adjacent to Mammoth Mountain and measures 20 miles long by 11 miles wide. A caldera is basically a depression formed after the eruption of magma to the surface.
Does California have caldera volcanoes?
Long Valley Caldera and the Mono-Inyo Craters chain form a large volcanic complex in eastern California that has had persistent earthquake activity and ground uplift in recent decades. Volcanoes have been active in the area for millions of years, and future eruptions are certain to occur.
Will the Long Valley Caldera erupt?
Geological studies of Long Valley Caldera and the Mono-Inyo Craters volcanic chain indicate that: Future eruptions are more likely to occur somewhere along the Mono-Inyo Craters volcanic chain than from the resurgent dome or south moat area within the caldera.
Where is the caldera of a volcano located?
A caldera is a large depression formed when a volcano erupts and collapses. During a volcanic eruption, magma present in the magma chamber underneath the volcano is expelled, often forcefully. When the magma chamber empties, the support that the magma had provided inside the chamber disappears.

Is Long Valley Caldera still active?
The Long Valley Caldera is only one part of a large volcanic system in eastern California that also includes the Mono-Inyo Craters volcanic chain. This chain extends from Mammoth Mountain at the southwest rim of the caldera northward 25 miles to Mono Lake. The volcanic system is still active.
Is Long Valley Caldera bigger than Yellowstone?
A GIANT supervolcano hidden beneath California could be an equal if not greater threat to the US than Yellowstone volcano, scientists have revealed. The 20-mile long Long Valley Caldera in eastern California is one of the world’s largest volcanic calderas.
How calderas are formed?
When an erupting volcano empties a shallow-level magma chamber, the edifice of the volcano may collapse into the voided reservoir, thus forming a steep, bowl-shaped depression called a caldera (Spanish for kettle or cauldron).
Is there volcano in Los Angeles?
There are no volcanoes in Los Angeles. The closest volcanic activity is the Lavic volcanic field and Coso volcanic field.
How many earthquakes have taken place inside the Long Valley Caldera?
TYPICAL BEHAVIOR:Since 1980, typical background geologic activity in the Long Valley area has included as many as 20 earthquakes of magnitude 2 or smaller a day, occasional swarms of magnitude 3 and larger earthquakes (felt locally), and uplift of the center of Long Valley Caldera at a rate of about 1 inch per year.
