LIMA — A 7.3 magnitude earthquake shook southern Peru on Sunday, killing at least two people and injuring 65, the South American country’s civil defense agency said.

Homes made of adobe collapsed in coastal areas most directly affected by the quake, local authorities said.

The earthquake struck in the Pacific, 31 kilometers (19 miles) from the seaside town of Acari in the region of Arequipa, according to the US Geological Survey.

"There are two fatalities in the region of Arequipa and so far 65 injured have been reported," said General Jorge Chavez, head of the National Civil Defense Institute.

Chavez said military planes were delivering humanitarian aid including tents to affected areas.

An emergency will be declared in most of the stricken areas so that reconstruction of homes and roads can begin immediately, said Mercedes Araoz, president of the Council of Ministers.

One person died in the Yauca district and another in the Bella Union district, both in the Arequipa region, where rescue workers were trying to help those affected, Peru’s Civil Defense said.

Peruvian President Pedro Pablo Kuczynski traveled to the region and flew over the quake zone. Speaking to reporters, he attributed the two deaths to adobe houses collapsing.

About 47 percent of homes in Peru, or 3.6 million, are made of clay, earth, stone or wood materials that are vulnerable in earthquakes, according to government statistics from 2014.

The Peruvian navy and the Pacific Tsunami Warning Centre in Hawaii ruled out the threat of a tsunami.

Adobe houses were leveled in the coastal town of Lomas and elsewhere in the surrounding area, Santiago Neyra, the mayor of the nearby town of Caraveli said.

Electricity was out in several municipalities and many roads were closed or passable in only one direction, the mayor said.

Structural damage was reported to a bridge in Arequipa, said the head of the region’s highway police, Major Alberto Rojas.

In the city of Arequipa, residents ran into the streets after the quake struck at 4:18am.

It was even felt in the capital Lima, hundreds of kilometres away.

"Here at the clinic the tremor felt super long," a patient in a Lima private hospital said.

The earthquake rocked Peru just before Pope Francis is slated to arrive Thursday for a three-day visit after touring Chile.

Peru lies on the so-called "Ring of Fire" -- an arc of fault lines that circles the Pacific Basin and is prone to frequent earthquakes and volcanic eruptions.

The South American country records about 200 earthquakes a year, most of them going unnoticed by the public.

The last major earthquake to shake Peru hit in August 2007, killing 595 people.

A 6.3-magnitude quake was felt in southern Peru on the border with Chile last October, leaving four people with slight injuries. — AFP
