   Early winter in Long Valley, 2017. Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth Mountain. The valley is one of the Earth's largest calderas, measuring about 20 mi (32 km) long (east-west), 11 mi (18 km) wide (north-south), and up to 3,000 ft (910 m) deep. Long Valley was formed 760,000 years ago when a ...

   The 16 x 32 km (20 x 10 mi) Long Valley caldera east of the central Sierra Nevada Range formed as a result of the voluminous Bishop Tuff eruption (considered a "supereruption") about 760,000 years ago. Summary. Resurgent doming in the central part of the caldera occurred shortly after the caldera-forming eruption.

   Nature 29 October 2023. By Carly Cassella. Long Valley Caldera. (Joshua Hammari, BLM/Wikimedia Commons) A new study from researchers at the California Institute of Technology (CIT) suggests the Long Valley Caldera in eastern California is restlessly tossing and turning as its deep magma chamber cools down for a big, long sleep.

   FS 2014-3056. Living With a Restless Caldera—Long Valley, California. Scientists have monitored geologic unrest in the Long Valley, California, area since 1980. In that year, following a swarm of strong earthquakes, they discovered that the central part of the Long Valley Caldera had begun actively rising. Unrest in the area persists today.

   When did a volcanic eruption occur in Long Valley?

   • The most recent volcanic eruptions in the area occurred in Mono Lake sometime between the mid-1700's and mid-1800's. Today, Long Valley occupies the eastern half of this 10-mile-wide, 20-mile-long caldera. Magma still underlies the caldera and heats underground water.

   Does the Long Valley volcano still exist?

   • Today, the Long Valley volcano exists in a relatively sluggish state. But all is not quiet on California's eastern front. In the late 1970s, a swarm of earthquakes began to emanate from the caldera – a depression that sits atop the buried volcano.
