    Long Valley Volcano | John Seach. California, USA. N, W summit elevation m Caldera. Long Valley Volcano is located in central eastern California. The caldera contains hot springs and fumaroles. The caldera is 15 x 30 km in diameter. In April three skiiers were asphyxiated by poisonous gas after falling into a volcanic. Geologic Summary: Lookout Mountain is a volcano and high point in the NW Moat of the caldera and outside the area of uplift associated with the Resurgent Resurgent Dome is an area inside the caldera that was built up by volcanism and uplift. Most of the m ( feet) of uplift occurred within the first , years of the caldera formation as magma intruded the .

    The Long Valley Caldera, located along the eastern escarpment of the Sierra Nevada mountain range, formed ky ago with the eruption of ~ km 3 of rhyolite we now call the Bishop Tuff. The caldera sits between two range-front normal faults: the Hilton Creek Fault to the south and the Hartley Springs Fault to the north (Fig. 1). Long Valley Caldera hosts a large hydrothermal system, with hot groundwater, boiling springs, and hydrothermal system is recharged with water primarily from snow-melt in the Sierra Nevada highlands along the western rim of the water infiltrates to depths of a few kilometers where it is heated to at least °C ( °F) by hot rock near geologically .

      The supereruption in question occurred , years ago, carving a vast volcanic depression that’s 20 miles long and 10 miles wide, now known as the Long Valley Caldera near California’s. Long Valley Caldera is a depression in east California next to Mammoth valley is one of the Earth's largest calderas, the result of a gigantic volcanic valley is about 20 miles (32 km) long (east-west), 11 miles (18 km) .

In both cases, the extra-caldera seismicity is more energetic and persistent than intra-caldera activity underscoring the importance of tectonic-magmatic interactions.

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) and 11 mi (18 km) wide (north-south). The elevation of the floor of the caldera is 6, ft (2, m) in the east and 8, ft (2, m) in the west.

Ongoing volcanic eruptions in Hawaii and Guatemala are leading to speculation that volcanism in general may be on an upswing. The anecdotal evidence, at least, is tantalizing: There have been about 25 major eruptions around the world from tocompared to 65 for the entire 20 th Century.
