A 6.8-magnitude earthquake hit northern Peru on Wednesday, the U.S. Geological Survey reported.
Authorities did not immediately report any victims or significant damage.
The temblor struck at a depth of 90 miles, about 350 miles north-northeast of Lima and about 50 miles north of Pucallpa, at 12:46 p.m. local time (1:46 p.m. ET), the USGS said.
The epicenter is also about 130 miles west of Cruzeiro do Sul in western Brazil.
The quake shook buildings hundreds of miles away in the capital and temporarily interrupted phone service there, and postings on social network sites say Ecuador and Brazil felt the quake, according to El Comercio newspaper in Lima.
El Comercio reported that people in the cities of Moyobamba, Loreto, Ica and Trujillo also felt the quake.
The USGS considers anything above 6.0 magnitude a "strong" quake.Read CNN's full coverage of the earthquake in Peru
