Chile struck by more earthquakes

SANTIAGO, Chile, March 16 (UPI) -- Another pair of earthquakes rattled coastal Chile overnight, the U.S. Geological Survey reported.

A 6.7-magnitude quake struck Monday before midnight and a 5.5-magnitude tremor rumbled just after midnight, CNN reported Tuesday.

USGS indicated both quakes were about 35 to 45 miles north of Concepcion, which was heavily damaged by a huge 8.8-magnitude earthquake Feb. 27.

Vicente Nunez, Chile's National Emergencies Office director, called for calm, saying there was no threat from a tsunami. He said he had no initial reports of injuries or major damage.

Since Sunday, aftershocks have rocked Chile, with at least seven of 5-magnitude or above recorded.
