Cleveland dome still growing
Satellite data indicated a persistent thermal anomaly at the summit of Cleveland Volcano Sept. 3-6, 2011. The growing lava dome in the summit crater has prompted officials to raise the alert level.
As of Sept. 8, scientists at the Alaska Volcano Observatory have received no further information about unrest at the volcano. Unclear satellite views of the summit and lack of real-time seismic data leaves scientists unable to track or predict eruptive activity.
Inflating volcanoes of South America: Scientists learn what fuels a super eruption
High in the Andes Mountains, a few volcanoes have been inflating for decades despite not having erupted in hundreds of thousands of years. Geophysical Institute scientists lead a South American-based project to study the world’s largest body of magma and its implications in a land of super eruptions.
Volcanic ash monitoring goes three-dimensional
When Assistant Research Professor Peter Webley arrived at the Geophysical Institute in 2005 he wondered why volcanological data was plotted in two dimensions when it was being computed in three dimensions. At a point when virtual globes were gaining mainstream momentum through programs like Google Earth, it seemed logical to use real-time imaging to display volcanic activity rather than static graphs.
Alaska Satellite Facility's Open House to celebrate 20 years of service
The Geophysical Institute’s Alaska Satellite Facility will celebrate 20 years since the first downlink of images from an earth-observing synthetic aperture radar (SAR) satellite by hosting an Open House. The public is invited to tour facilities used for the acquisition, storage, processing and distribution of data acquired from polar-orbiting satellites, and to learn why satellite-borne earth observation is critical for monitoring change.
GI demonstration at Tanana Valley State Fair
Tuesday, August 9 is UAF Day at the Tanana Valley State Fair! This year, several units from the Geophysical Institute will participate with demonstrations in Totem Square from noon until 6 p.m. Staff from the Alaska Satellite Facility, Poker Flat Research Range and the Alaska Volcano Observatory will be available to talk about remote sensing and ASF’s 20th anniversary, display some new unmanned aircraft, as well as volcanic ash modeling. Stop by the GI’s tent to witness some of the exciting research done by our very own faculty, staff and students.
The Science for Alaska Lecture Series: A winter tradition
For Immediate Release
For more than a decade, the Science for Alaska Lecture Series has provided Anchorage residents the latest findings in scientific research relevant to all Alaskans. Traditionally, the lectures are offered during January and February, and serve as an educational and entertaining option for all ages on cold winter nights.
PDF DownloadThe year of the Alaska volcano
For Immediate Release
FAIRBANKS, Alaska—Three Alaska volcanoes erupted in midsummer 2008. Cleveland, Okmok and Kasatochi volcanoes, all located in Alaska’s Aleutian Chain, made for a hectic 20th anniversary for the Alaska Volcano Observatory.
Satellite images spot Augustine Volcano's steam plume
For Immediate Release
A MODIS satellite image, captured by the Geographic Information Network of Alaska, confirms pilots' sightings of a steam plume emerging from Augustine Volcano. The plume appears to be primarily steam, but reports of a sulfurous smell have been reported by surrounding communities to the Alaska Volcano Observatory. The plume extends an estimated 50 miles from the volcano.
