New evidence for frequent large tsunamis at a remote island near Dutch Harbor, Alaska provides geological data to aid tsunami hazard preparedness efforts around the Pacific Rim. Recent fieldwork in Alaska’s Aleutian Islands suggests that a presently “creeping” section of the Aleutian Subduction Zone fault could potentially generate an earthquake great enough to send a […]
On a clear day last spring, fire sizzled on water at Poker Flat Research Range in the Chatanika River valley. There, scientists were spilling crude oil in a manmade water basin and torching it from above. A series of similar test burns were part of a team effort between university scientists and researchers with the […]
For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryonic salmon and herring exposed to very low levels of crude oil […]
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 […]
