Alaska has the greatest tsunami potential of any state in the nation. A tsunami may be generated after an earthquake occurs, traveling within minutes to coastal communities. Currently, work is underway to estimate potential flooding areas along the Alaska coast in case of a local or distant tsunami. This work is called tsunami inundation mapping. Once these maps are complete, communities can produce evacuation routes and plan other measures to save lives and property should a tsunami strike. 
Students participating in a geology field camp with University of Alaska Fairbanks faculty found the fossilized footprint from a small meat-eating dinosaur in Denali National Park in June 2005. That fossilized footprint is the first concrete evidence that dinosaurs once roamed Alaska's Interior. What did the Interior and the rest of Alaska look like eons ago when dinosaurs covered the landscape? The answer lies within fossilized plants and the characteristics of rocks that contain fossil footprints.
In Alaska, finding your way into bear country is easy. All three North American species of bears are present and there is about one bear to every five human residents in our state. This close proximity spurs many bear stories, myths, and misconceptions.
As the Arctic climate warms, permafrost begins to thermally degrade. Transformation of this frozen layer of earth triggers changes in every aspect of surface water and energy in the Arctic. While the region experiences warming, permafrost becomes thinner, and its extent in the boreal forest shrinks.
Alterations to permafrost also influence the look of the northern landscape and the region's climatology. In short, warming climate and thawing permafrost create changes to the entire hydrological cycle in Alaska.
For more than a decade, the Science for Alaska Lecture Series has provided Anchorage residents the opportunity to learn about scientific research conducted at the University of Alaska. This annual series, sponsored and coordinated by the Geophysical Institute, features a handful of scientists from the University of Alaska, along with experts from state and federal agencies. These experts share their research with the general public in lectures that are full of animations and visuals that appeal to all ages.

The Geophysical Institute has a professor and graduate student participating in the NASA hypervelocity re-entry campaign for the Stardust sample return capsule. The Stardust vehicle will release the capsule into Earth's atmosphere at 12:56 a.m. on Sunday, January 15. The capsule,
containing interstellar dust from the Wild 2 comet, will re-enter at a whopping 28,600 miles per hour. This re-entry is the fastest in NASA history.

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.
The Geophysical Institute, the Alaska Geological Society and ConocoPhillips welcome Kathryn Moran, an associate professor of ocean engineering and oceanography at the University of Rhode Island, to discuss findings from the 2004 Arctic Coring Expedition (ACEX) in a free public lecture
on October 14. Cores collected from the Integrated Ocean Drilling Program's ACEX mission are surprising many who believed the Arctic Ocean lacked sufficient remains to record evidence of ancient climate. Now scientists are able to analyze Earth's previous conditions through ribbons of ocean floor sediment taken from depths as deep as 1,300-feet below the sea floor.
