A magnitude 6.7 earthquake struck central Peru on Thursday, shaking communities in the Andes but causing no immediate reports of casualties or significant damage, authorities said.

According to the United States Geological Survey, the earthquake occurred at a depth of about 99 kilometers, or 62 miles, with its epicenter approximately 31 kilometers northwest of Aniso.

Peru’s Geophysical Institute initially estimated the earthquake at magnitude 7.2 before the magnitude was revised.

Hernando Tavera, head of the Geophysical Institute of Peru, said the considerable depth of the earthquake helped limit its impact at the surface.

“The population went out to the streets out of concern, but there is no impact,” Tavera told local radio station RPP.

Authorities continued assessing affected areas following the tremor, but there were no immediate reports of deaths, injuries or major structural damage.

Peru is highly vulnerable to earthquakes because it lies along the Pacific Ring of Fire, a seismically active zone where tectonic plates meet and a large proportion of the world’s earthquakes and volcanic activity occur.

The South American nation is also the world’s second-largest copper producer, making major seismic events a potential concern for mining operations and infrastructure.
