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 […]

You probably know that friction in the earth’s crust causes earthquakes, but did you know that a little extra sunshine might increase your chances of experiencing an earthquake if you live where glaciers are present?
