Mount Redoubt sounds off

Redoubt volcano plume

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. Follow us:by Share this:by


Monitoring volcanic activity at Mount Cleveland

Cleveland Volcano air 2012

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 […]

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. Follow us:by Share this:by
