Is Mammoth Mountain a volcano?
Mammoth Mountain is a 3,369-m (11,053-ft) high volcano lies west of the structural rim of the caldera and is considered to represent a magmatic system distinct from Long Valley Caldera and the Mono-Inyo Craters.
What type of volcano is Long Valley Caldera?
Hot Creek near the Long Valley supervolcano. The Long Valley Caldera is the depression formed from the supervolcano eruption 760,000 years ago, which ejected hot ash, lava and toxic gas.
Is the Long Valley caldera active?
The caldera remains thermally active, with many hot springs and fumaroles, and has had significant deformation, seismicity, and other unrest in recent years.
How long ago did Mammoth Mountain erupt?
The cones, whose name derives from colorful mantling scoria deposits, are unglaciated and were radiocarbon dated at about 8,000 years ago. Phreatic eruptions, distinct from those at South Inyo Craters, took place about 700 years ago from vents on the north side of Mammoth Mountain.
What is the most dangerous volcano in California?

Is Mt St Helens a supervolcano?
Mt. Saint Helens is not even the most likely volcano in the Cascades to produce a ” supervolcanic ” eruption. It has been very active over the last 10,000 years, but most tend to be small, bleeding out material frequently over this period.
Is Yellowstone about to erupt?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions.
Is Long Valley going to erupt?
The pattern of volcanic activity over the past 5,000 years suggests that the next eruption in the Long Valley area will most likely happen somewhere along the Mono-Inyo volcanic chain. However, the probability of such an eruption occurring in any given year is less than 1%.
What is the most dangerous volcano in the US?
1: Kilauea volcano, Hawaii. Threat Score: 263. Aviation Threat: 48. This active volcano is continuously erupting and was given the highest threat score by the US Geological Survey.
What is the most dangerous supervolcano?
Yellowstone Caldera, Wyoming, USA Defined by incredible volcanic landscape of geysers and hot springs, the Yellowstone caldera is a supervolcano that hasn’t erupted for around 70,000 years – though beneath ground, it’s still very much active.
Which supervolcano is most likely to erupt?
Over the past 640,000 years since the last giant eruption at Yellowstone, approximately 80 relatively nonexplosive eruptions have occurred and produced primarily lava flows. This would be the most likely kind of future eruption.
Is Mammoth going to erupt?
Mammoth Mountain is technically not an active volcano because it hasn’t erupted in the last 10,000 years. The last time Mammoth Mountain erupted was approximately 57,000 years ago. Mammoth Mountain itself isn’t a supervolcano, but the Long Valley Caldera is classified as a supervolcano.
