This earthquake was characterized by a thrust-faulting focal mechanism, caused by the subduction of the Nazca plate beneath the South American Tectonic Plates. The end-regions of the rupture zone coincided with the Andean oroclines of Maipo (33° S) and Arauco (37° S).
What was the cause of the 2010 Chile earthquake?
The Chilean quake was spawned by a straightforward dip of the Nazca plate (ocean crust undergirding the Pacific Ocean off South America’s coast) as it slips eastward under the continent’s crust, according to the USGS. Faults that combine sideways with up-and-down motions are called oblique by seismologists.

When was the last earthquake in Haiti?
The last major earthquake to strike Haiti’s side of the island was in 1860. Yesterday’s initial earthquake, which struck at about 5 p.m. local time yesterday, spawned dozens of aftershocks, about 15 of which were magnitude 5 or greater.
How many people died in Haiti earthquake?
2010 Haiti earthquake, magnitude 7.0 earthquake that struck some 15 miles (25 km) southwest of the Haitian capital of Port-au-Prince on January 12, 2010. Haiti’s government estimated that more than 300,000 were killed, but other estimates were considerably smaller. Hundreds of thousands of survivors were displaced.
Can “megaquakes” really happen?
Megathrust earthquakes occur at subduction zones at destructive convergent plate boundaries, where one tectonic plate is forced underneath another, caused by slip along the thrust fault that forms the contact between them. These interplate earthquakes are the planet’s most powerful, with moment magnitudes that can exceed 9.0. Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes.
Why are earthquakes so devastating in Haiti?
Why can earthquakes in Haiti be so devastating? It’s a combination of factors that include a seismically active area, a high population density of 11 million people and buildings that are often designed to withstand hurricanes — not earthquakes.
