Cabled ocean-floor observatories record ground shaking and pressure variations, which contribute to early warning systems and give us a unique view of the ocean–crust coupling.
As wildfires blaze through the Arctic, scientists examine the role of landscape characteristics on wildfire ecosystem responses in northern aquatic ecosystems.
Research over the past decade in Alaska’s Aleutian Islands has offered surprising insights into the pulses of great earthquakes that generate dangerous, often long-distance tsunamis.
Researchers tracked 19 maritime glaciers in Kenai Fjords National Park over several decades and found that tidewater glaciers tended to experience less ice loss than other types of glaciers.
“Beautifully long arguments” between an American scientist and a Russian researcher helped clarify several fundamental assumptions about permafrost thaw.
More accurate aftershock zones reveal that the rupture areas of megathrust Aleutian–Alaska earthquakes are larger than we thought and partly overlap, in contradiction with the seismic gap hypothesis.
Cloud-to-ground lightning is found to be the most important controller of wildfire occurrence in the Artic tundra of Alaska from 2001 to 2019.
Increasing incidents of wildfires in the Arctic are not only thawing permafrost but changing the entire underlying structure of the region.
Miners in Alaska rerouted a river to search for gold. One hundred years later, the new channel is teaching scientists how rivers shape Earth.
Observations of cross-polar cap neutral winds near 240 km altitude stalling over short distances in the midnight sector near Poker Flat, Alaska, challenge the standard view of high-latitude dynamics.
