Volcanology

Volcanoes give us important information about their behavior from their temperature. However, getting close enough to take a volcano’s temperature is often a dangerous undertaking. In the past, measurements required the volcanologist to get uncomfortably close to the activity. Recent advances in digital infrared imaging allow volcanologists to measure temperatures from a safe distance and over large areas with infrared cameras.
Although it's been more than a year since Mount Augustine had its memorable eruption, work continues for University of Alaska Fairbanks researchers. The work of Alaska Volcano Observatory employees from UAF's Geophysical Institute will be appearing in the upcoming issue of the journal Science.

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.
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.
South-central Alaska's Mount Wrangell rumbled for 11 minutes following the Sumatra earthquake in December 2004. A swarm of 14 earthquakes were triggered at Mount Wrangell about one hour after the initial rupture in Indonesia, more than 6,800 miles away.
As Alaska cools and hardens, many scientists are reacquainting themselves with their offices. Such is the case for Derek Sikes, the curator of insects at the University of Alaska Museum of the North. This summer, he traveled across Alaska, from Sagwon Bluffs to Sitka and many places between, including a trip to the Aleutians for good lateral coverage. Sikes’ tales of his recent insect explorations in Alaska have a Lewis and Clark feel. Scientists have inventoried the insects of Alaska for a long time, but those men and women were very few compared to the researchers studying caribou or the aurora. Because of this dearth of people looking for bugs, Alaska’s rock crevices and tidal splash zones still hide plenty of undiscovered species. Sikes and his colleagues have added more than 1,000 to the Alaska list of insects (and have collected 20 that are new to science) since he moved northward and started work at the museum four years ago. During the short period when insects are crawling, flying and hopping, he jumps at every opportunity to find more.
On June 6, 1912, if you happened to be sitting on a log outside your cabin near Fairbanks, Juneau or Dawson City, you would have heard an explosion.
“This morning the seismic tremor was down just a little bit from yesterday. We’re hoping it calms down before too long, but it might last for awhile.”
