Alaska is a globally significant reservoir and distribution point for viruses carried by birds.
The Alaska Volcano Observatory reports that a swarm of small earthquakes occurred somewhere deep below the iconic crater beginning on April 11 — but it’s too early to tell if that signals an eruption could be on the way.
Geologists say the conditions that can lead to landslide-generated tsunamis are only getting more pronounced in Alaska.
The quake has triggered a tsunami warning for a swath of coastal Alaska from Sand Point to Kodiak to Homer to Cordova, and prompted sirens to sound in communities as evacuations began.
USGS biologist Sarah Schoen said the project started about five years ago when a major heat wave, known as “the blob,” hit the ocean. Around the same time, there was a die-off of an estimated million common murres — a northern seabird — from Alaska down to California.
State program officials say it will take a lot of money and many more years to do the kind of landslide assessment work the state needs.
The new data has allowed researchers to drop their worst-case estimates for Whittier from a 30-foot wave to a 7-foot wave.
As storms that were once thought of as extreme become more common, storms that are thought of as impossible — or at least extremely unlikely — start to become real concerns.
The U.S. Congress has appropriated more than $3.6 million to monitor transboundary watersheds and for diplomatic efforts in cross-border negotiations with Canada.
Landslides in Southeast Alaska often happen with rainfall soaking soils over time, followed by a sudden, torrential downpour that shifts the balance between friction and gravity.
