Slow But Not Quite Silent
Department or Administrative Unit
Faults at subduction zones—regions where one tectonic plate dives beneath another—generate the world's largest earthquakes, which rapidly release strain over large areas of the plate interface. In recent years, a much slower form of strain release has been detected in many subduction zones throughout the world. It involves episodes of fault slip that resemble conventional earthquakes, except that faulting occurs slowly, often lasting weeks or months.
