WFS News: X-raying the Earth with waves from stormy weather ‘bombs’

Using a detection network based in Japan, scientists have uncovered a rare type of deep-earth tremor that they attribute to a distant North Atlantic storm called a “weather bomb.” The discovery marks the first time scientists have observed this particular tremor, known as an S wave microseism. And, as Peter Gerstoft and Peter D. Bromirski […]
