Earthquake off the coast of Chile – 8.3 magnitude, a powerful quake – on September 16, 2015.
The U.S. Geological Survey (USGS) has reported an 8.3-magnitude earthquake that struck in the Pacific Ocean, off the coast of Chile, on September 16, 2015. The quake occurred at 22:54 UTC (7:54 p.m. local time in Chile, or 5:45 p.m. Central Daylight Time) at a depth of 20.5 miles (33 km). At this writing, tsunami waves – at least one measuring 10 feet in height (about 3 meters) have struck the coast of Chile, and the Pacific Tsunami Warning Center had a tsunami warning still in effect for Hawaii, approximately two hours after the quake.
According to CNN, there were reports of damages to homes in Illapel. A strong aftershock could be felt in the country’s capital, CNN sister network CNN Chile reported.
Details of the quake from USGS follow:
Time

Nearby Cities
54km (34mi) W of Illapel, Chile
76km (47mi) WNW of Salamanca, Chile
109km (68mi) NNW of La Ligua, Chile
118km (73mi) SSW of Ovalle, Chile
233km (145mi) NNW of Santiago, Chile
Earthquakes are common along the coast of Chile. USGS explained:
The September 16, 2015 M 8.3 earthquake west of Illapel, Chile, occurred as the result of thrust faulting on the interface between the Nazca and South America plates in central Chile. At the latitude of this event, the Nazca plate is moving towards the east-northeast at a velocity of 74 mm/yr with respect to South America, and begins its subduction beneath the continent at the Peru-Chile Trench, 85 km to the west of the September 16 earthquake. The size, location, depth and mechanism of this event are all consistent with its occurrence on the megathrust interface in this region.
