Ecuador ? A powerful earthquake shook the border region of Ecuador and Peru late Thursday, but there were no immediate reports of injury or damage.

Local media said the magnitude 6.7 quake was felt strongly in the Ecuadorean cities of Guayaquil and Manta.

The U.S. Geological Survey said the temblor struck at 10:12 p.m. and was centered about 150 miles south of Guayaquil, the Andean nation’s largest city and main port.

The quake came after a magnitude-7.7 tremor shook northern Chile on Wednesday, killing two people, injuring more than 150 and leaving 15,000 homeless.

Strong aftershocks continued to rattle Chile on Thursday, with one tremor measuring magnitude 6.2 and another magnitude 6.8, according to the U.S. Geological Survey.

Chile’s, Peru’s and Ecuador’s Pacific coastlines all lie along the intersection of the Nazca and South American tectonic plates, one of the world’s most seismically active regions.
