Volcanoes are an awe-inspiring and hazardous part of our planet. And now, they’re being made to sing. Scientists are turning seismic data into audio data in order to grasp just what’s going on deep in the Earth’s crust, and better forecast future explosive eruptions.
On Saturday May 4th 2013 the Alaska Volcano Observatory detected a series of low-level explosions at Cleveland volcano. Three discrete explosions occurred at 5:00 am, 9:17 am, and 11:44 am Saturday, while subsequent less powerful rumbles on Sunday denoted an ongoing low-level eruption. The sequence of eruptions emitted ash, gas, and steam into local airspace. […]
One hundred years after the largest volcanic eruption of the 20th century, the Valley of Ten Thousand Smokes is still a moonscape of ash and volcanic rock, without a tree or shrub in sight. The valley, located on the Alaska Peninsula where the Aleutians hook on to mainland Alaska, is a silent reminder of the […]
LLiz O’Connell for Frontier Scientists – Early on Bob Gill, Research Wildlife Biologist with the U.S. Geological Survey (USGS), thought Bar-tailed Godwits’ journey from Alaska to New Zealand was a non-stop flight. Faced with skepticism from his colleagues, but armed with satellite technology, Gill tagged a female Godwit he named E-7. By tracking E-7 in […]
Matthew Sexson and Paul Laustsen for USGS – ANCHORAGE — On its way to deliver emergency fuel to Nome, Alaska, the Russian tanker Renda will move through an area used by wintering spectacled eiders, a federally threatened sea duck. But, to protect the ducks and their wintering habitat, resource managers from the U.S. Fish and Wildlife Service and navigators from the U.S. Coast Guard are […]
Roughly translated and abbreviated; ASH? WHAT ASH? *#/! ASH!, was the conversation between the Anchorage control tower and the KLM pilot who had the misfortune of flying through a volcanic ash cloud on a December morning in 1989. It was dark, as it is most December mornings in Alaskan North.
With active volcanoes as close as 80 miles of Anchorage city limits, Alaskans are grateful for the professional volcano watchers who work in a nondescript building on the campus of Alaska Pacific University, topped with a massive array of tracking and communication instruments. “The August 18, 1992 Spurr eruption, sent an ash cloud here that […]
The scientists at the United States Geological Survey – Alaska Volcano Observatory (USGS-AVO) in Anchorage, Alaska don’t only have an impressive title – volcanologists – they also pursue an engaging, challenging career. Alaska contains over 130 volcanoes and volcanic fields.
