Global quake evidence found by scientists 3800 yrs

A new research finds evidence that the greatest earthquake ever recorded by humans occurred 3,800 years ago in northern Chile.

Tsunamis impacted nations as far away as New Zealand, and experts at the University of Southampton said that boulder-sized automobiles were dragged inland by the waves.

Longer ruptures, they reasoned, imply a larger earthquake since earthquakes are caused by the rubbing together of two tectonic plates.

An earthquake that hit Chile's coast in May 1960, with a rupture zone of 621 miles, was the biggest known quake prior to the current research, the US Geological Survey said.

Although we have discovered evidence of a 1,000-kilometer-long crack off the coast of the Atacama Desert, it is immense

A tsunami generated by an earthquake with a magnitude of 9.5 or more in northern Chile could only have moved those boulders
