The magnitude-7.1 quake hit at 4:18am (local time) on Sunday at a depth of around 10 km, the US Geological Survey said.
A powerful natural disaster struck off Peru's coast early today, prompting a U.S. agency to issue a tsunami threat message for parts of the country and neighbouring Chile.
A huge natural disaster off south-western Peru's Pacific coast has killed at least one person and injured at least 65, as buildings collapsed.
"There are two fatalities in the region of Arequipa and so far 65 injured have been reported", General Jorge Chavez, head of the National Civil Defense Institute, said.
Several municipalities were without electricity, and many adobe houses had collapsed, Osorio said.
No damage or casualties have been reported.
According to the Pacific Tsunami Warning Centre, tsunami waves are possible within 300 km of the epicentre along the coast of Peru.
Magnitudes between 7.6 and 7.8Earthquakes of this size may produce destructive tsunamis especially near the epicenter; at greater distances small sea level changes may be observed.
Earthquakes are fairly common in Peru, which is on the so-called "Ring of Fire" - an arc of fault lines that circles the Pacific Basin.
In August 2016, a 5.4 quake centered in southern Peru and killed nine people and left 40 injured.
The Peruvian coast was rocked by a 7.1 magnitude quake Sunday morning.
