Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on. Now, graduate students at the University of Washington have found a way to detect volcanic activity in the atmospheres of exoplanets, or those outside our solar system, when they transit, or pass in front of their host stars. […]
SALT LAKE CITY – 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. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand […]
North America’s highest mountain should be a volcano. Denali sits about 60 miles above where the Pacific Plate grinds beneath the North American plate, as do Iliamna, Redoubt and Augustine. If you draw a line from the Aleutians to volcanic features in interior Alaska, the curve goes over Denali’s summit. Like its neighbors in the […]
Augustine Volcano sits alone, a 4,000-foot pyramid on its own island in Cook Inlet. Like many volcanoes, it has a tendency to become top heavy. When gravity acts on Augustine’s oversteepened dome, rockslides spill into the ocean. A scientist recently found new evidence for an Augustine-generated tsunami from a time when Egyptian pharaohs built their […]
