According to the survey's updated figures, the quake occurred at 2321 GMT on Sunday and was centred about 42 kilometres east-northeast of Tambo town and had a depth of 101 kilometres.

The quake sent people rushing into the streets in Ayacucho city which has a population of 150,000. In Cusco in southeastern Peru, cellphone and power outages were reported.

The quake came just hours after a powerful 6.0 earthquake injured nearly 200 people and damaged buildings in the San Francisco Bay area in California.
