The U.S. Geological Survey said the quake, registered at 12:45 p.m. local time, occurred at a depth of 90.2 miles. Its epicenter was 50 miles north of Pucllpa, Peru, 130 miles west of Cruzeiro do Sul, Brazil, 195 miles northeast of Huanuco, Peru, and 352 miles north-northeast of Peru's capital, Lima.
Voice of America said there were no immediate reports of injuries or damage as a result of the temblor, which was centered in a jungle region near the Brazil border.
The network noted that in 2007 an 8-magnitude quake along Peru's central coast killed at least 540 people. The South American country is situated near two tectonic plates, making it susceptible to earthquakes.
