M8.2 EARTHQUAKE GENERATES LOCAL TSUNAMI IN NORTHERN CHILE, 01 APRIL 2014

The 1 April 2014 magnitude 8.2 Mw Northern Chile earthquake (19.642 S, 70.817 W, depth 20 km) occurred at 2347 UTC and generated a tsunami that was observed all over the Pacific region and caused damage locally. According to  news reports, there were at least 7 dead due to the earthquake ground shaking and over 200 injured. There was tsunami port damage reported at the nearest city of Iquique, Chile, 79 km away from the epicenter and inundation along the coasts of Pisagua and Arica. In February 2010, a magnitude 8.8 Mw located near the central coast of Chile generated a tsunami that caused 156 fatalities.

According to the USGS, the 1 April 2014 earthquake off the Chilean coast occurred as a result of shallow depth thrust faulting slip on the primary plate boundary interface between the Nazca and South American plates. In the region of the earthquake, the Nazca plate subducts eastward beneath the South American plate at a rate of 65 mm/yr.
