6.3 magnitude earthquake hits northern Chile

Oct. 10 (UPI) -- A strong 6.3 magnitude earthquake hit northern Chile early Tuesday, the United States Geological Survey said.

The quake had a depth of 51 miles and its epicenter in Tarapaca was 45 miles east of the port city of Arica, and 54 miles southeast of the Peruvian city of Tacna, the USGS said.

Analysts said preliminary data indicates the quake to be a typical subduction earthquake, meaning the seismic event was probably triggered by a portion of the Pacific plate sliding under the South American plate.

Tectonic activity is common on the western edge of South America.

Because of its depth, experts said the quake would have been felt in southern Peru and even in Argentina.

Residents say while the quake was strong, there were no widespread communications or power outages.

No tsunami warnings were issued and no injuries were reported. Damage is still being assessed.
