California supervolcano is cooling off but may still cause quakes

Since the 1980s, researchers have observed significant periods of unrest in a region of California's Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost ...

Study challenges widely accepted theory of Yellowstone formation

Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held ...

Supervolcanoes likely triggered externally, study finds

Supervolcanoes, massive eruptions with potential global consequences, appear not to follow the conventional volcano mechanics of internal pressure building until the volcano blows. Instead, a new study finds, such massive ...

Scientists see deeper Yellowstone magma

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber.

Supervolcano triggers recreated in X-ray laboratory

Scientists have reproduced the conditions inside the magma chamber of a supervolcano to understand what it takes to trigger its explosion. These rare events represent the biggest natural catastrophes on Earth except for the ...

Utah supervolcanoes discovered

(Phys.org) —Brigham Young University geologists found evidence of some of the largest volcanic eruptions in earth's history right in their own backyard.
