The magnitude 6.7 quake was felt throughout Ecuador and in northern Peru . The U.S. Geological Survey said it was centered about 234 kilometers (151 miles) south-southeast of Guayaquil , Ecuador's largest city and its main port.
"It was felt strongly. It lasted 50 seconds," business student Vanessa Ochoa, 24, told The Associated Press from the Ecuadorean jungle city of Puyo .
"There are reports that the quake was felt throughout the country," Ecuador 's Geophysics Institute said. "So far there were no reports of damage."
Peruvian Civil Defense officials told Lima radio station Radioprogramas that the quake was felt strongly in cities in northern Peru but there were no reports of damage.
The quake came after a magnitude-7.7 temblor 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.
