What is now Southeast Alaska – called the Alexander terrane by geologists – probably started out near the equator.

With permafrost thaw in the Arctic rapidly outpacing previous projections, researchers are racing to understand the impacts of an increasingly unstable future.

Today, most climate science is done with satellites, sensors and complicated computer models. But it all started with two glass tubes.

Many Alaskans will get a tsunami warning on Wednesday at 10:15 a.m. It’s a test, but the people sending it out are worried that not everyone will know that.

Activity at the volcanoes peaked between March 9 and 11.

Alaska’s coastal erosion problems have led to a growing field of research into what can be done about it.
