A few days ago, the forces beneath Alaska rattled people within a 500-mile radius: A magnitude 7 earthquake ripped under Hubbard Glacier. The earthquake’s main shock and aftershocks have revealed something else — a possible slash across the face of Alaska long buried by glacial ice, a feature that professionals speculated upon decades ago.

Research at the University of Alaska Fairbanks Geophysical Institute is advancing the ability to quickly clean up Earth’s radiation belts from a flood of energetic electrons created by an extraordinary solar blast or a nuclear explosion in space. Many of these incoming electrons become trapped in the Earth’s outer radiation belt and can damage […]
The climate-driven spread of beaver ponds in Alaska’s Arctic accelerates the effects of a warming environment by causing pond-adjacent permafrost to thaw and by increasing the amount of liquid water present during winter. Those are the key findings of the first comprehensive, on-the-ground assessment of the northward migration of beavers. The research was led by […]
An unusual triple whammy of solar outbursts, including one scientists call a cannibal, began hitting Earth this afternoon and is likely to bring the curtain up on spectacular aurora performances starting tonight. Events like this bring a risk of radio blackouts and satellite damage, according to the Space Weather Prediction Center of the National Oceanic and Atmospheric […]
