The magnitude‐7.9 earthquake that shook Alaska on 3 November not only is one of the largest quakes ever recorded on U.S. soil. It is also the first recorded quake beneath a glacier, according to Peter Haeussler, a geologist with the U.S. Geological Survey, who has been helping to lead surveys of the quake after‐effects. “It is amazing how clear the details of the fault traces show up,” he said. “Some cracks are easily large enough to fit a bus in, where the fault pulled ice blocks away from each other.”
