After the 2010 earthquake-tsunami dual disaster in Chile, scientists believe the risk of yet another quake has increased. The 8.8 magnitude quake occurred where the Nazca Plate (which is an oceanic lithospheric plate) subducts under the South American mainland at a rate of 6.8 centimeters a year. The 2010 quake did not fully release the built-up energy that has been increasing since 1835. When the pressures between the two plates build up enough, they will snap and cause another earthquake. Chile is highly prone to violent earthquakes especially since subducting plates can create extremely powerful quakes.
