Scientists at Oregon State University have determined why foreshocks are such common indicators of large and deadly earthquakes.
Scientists involved in groundbreaking new research at Oregon State University have determined that major earthquakes are often preceded by “silent slips” and have finally discovered why foreshocks are common indicators of large and deadly earthquakes.
According to Oregon Live, major earthquakes normally follow “shallow mantle creep” and “seismic swarms,” and researchers are much clearer in their understanding now of the “silent slip,” which is what happens when different sections of the Earth’s crust can be observed shifting along the fault line. However, when this occurs, no seismic activity is ever detected, which has been confusing to researchers in the past.
