The earthquake’s epicenter was at an approximate depth of 115 km, according to USGS, and could be felt as far afield as Lima, Peru; Caracas, Venezuela; and Quito, Ecuador.
There are reports of injuries and damages to homes and roadways, Peru’s President Martin Vizcarra said in a statement on state TV.
The most affected areas were the cities of Yurimaguas and Tarapoto in the Peruvian Amazon, Vizcarra said.
“We already have reports of injuries, of affected homes, collapsed highways and a bridge that connects Yurimaguas with Tarapoto has also collapsed,” Vizcarra said.
The country’s civil protection agency is sending teams to the affected areas, he added.
Two of the injured are from the city of Yurimaguas, and the other injuries were from other provinces in the Amazon region, the ministry said.
“We are evaluating the affected areas. I ask all of our citizens to remain calm.”
The earthquake was the strongest in Peru in 12 years, Vizcarra said.
The country’s interior ministry tweeted photos of damaged houses in the northern Amazonas region, adding that police were on site to protect affected areas.
Ecuador’s President Lenín Moreno also tweeted: “I am awaiting of the information about the strong earthquake recorded this morning.”
