The largest earthquakes on Earth occur at the interface between the two plates, called the megathrust. Recent examples include the magnitude 8.8 earthquake in Chile in February 2010 and the magnitude 9.1 earthquake offshore Sumatra in December 2004; the latter triggered a devastating tsunami.
Earthquakes usually happens along a fault plate, the border between plates: Global plate tectonic map (click to enlarge the map). Earthquakes often trigger landslides, tidal waves and tsunamis. Powerful aftershocks frequently occur, causing further damage and increasing psychological stress.ntensity scales, like the Modified Mercalli scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce.
