A new project will make it possible for scientists to better track a suite of phenomena in Alaska ranging from earthquakes to wildfires to sea ice. The five-year, $6.9 million project funded by the National Science Foundation will enhance measurements of Arctic change across western and northern Alaska. It’s led by the Alaska Earthquake Center, […]
Forty-one volcanoes that have erupted since the 1700s. Eleven percent of the world’s earthquakes. Glaciers of an ever-changing number that probably tops 100,000. Alaska has its share of superlatives, and here’s another one — Alaska has the largest maar on Earth. What’s a maar? It looks a lot like a lake, it’s circular and […]
Two remote California desert communities assessed damage after two major earthquakes hit the area at the end of last week, followed by thousands of smaller aftershocks. Ridgecrest and neighboring Trona were hit hard by the magnitude 7.1 quake that rocked the Mojave Desert towns Friday. A day earlier, a magnitude 6.4 temblor hit the […]
Mathematicians have devised a way of calculating the size of a tsunami and its destructive force well in advance of it making landfall by measuring fast-moving underwater sound waves, opening up the possibility of a real-time early warning system. The sound waves, known as acoustic gravity waves (AGWs), are naturally occurring and can be generated […]
