The area of eastern California that includes the Long Valley Caldera and the Mono-Inyo Craters volcanic chain has a long history of geologic activity that includes both earthquakes and volcanic eruptions.
Oct 19, 2023 · What’s going on beneath the surface of the Long Valley Caldera, the site of a massive supervolcano eruption 760,000 years ago? A new study uses seismic waves to image the underground environment in the region and finds that the magma chamber is cooling off.
Oct 18, 2023 · The activity is concerning because the area, called the Long Valley Caldera, sits atop a massive dormant supervolcano. Seven hundred and sixty thousand years ago, the Long Valley Caldera was formed in a violent eruption that sent 650 cubic kilometers of ash into the air—a volume that could cover the entire Los Angeles area in a layer of ...
Long Valley Caldera in eastern California (here viewed from its southwest rim toward its northeast rim on the horizon 18 miles away) was formed about 760,000 years ago in a violent volcanic eruption that blew out 150 cubic miles of magma (molten rock) from beneath the Earth's surface.
Die Long Valley Caldera liegt im östlichen Teil des US-Bundesstaates Kalifornien an der Grenze zu Nevada, in Mono County etwa 25 km südlich des Mono Lakes. Sie ist ein aktives vulkanisches Gebiet, das aufgrund einer heftigen explosiven Vulkaneruption vor 760.000 Jahren auf einer Fläche von 544 km² (ca. 32 km mal 17 km Ost-West bzw.
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. The last time the volcano blew was roughly 100,000 years ago.
Future Eruptions in California's Long Valley Area - What's Likely? 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.
