Rare ‘boomerang’ earthquake observed along Atlantic Ocean fault line – Science Daily

Scientists have tracked a ‘boomerang’ earthquake in the ocean for the first time, providing clues about how they could cause devastation on land.Earthquakes occur when rocks suddenly break on a fault — a boundary between two blocks or plates. During large earthquakes, the breaking of rock can spread down the fault line. Now, an international team of researchers have recorded a ‘boomerang’ earthquake, where the rupture initially spreads away from initial break but then turns and runs back the ot…
