A 5.5 magnitude earthquake shook the Andes region of Peru, killing at least five people, authorities said Sunday. More than 20 people were injured and 300 have been displaced.

The U.S. Geological Survey reported the quake struck on Saturday at 9:24 p.m., with its epicenter located 2 kilometers (1.24 miles) west-southwest of the city of Sicaya in Huancayo province. It was 10 kilometers (6.21 miles) deep.

Peru’s National Civil Defense Institute said in a statement the total number of missing is still unknown. Several buildings collapsed or suffered structural damage, including the local church and convent.

Luis Vásquez, head of the local civil defense office, told journalists that the use of rustic adobe materials in construction in that Andean area “has contributed to the greater impact and damage."

Earthquakes are frequent in Peru, which is located in the so-called Pacific “Ring of Fire.”
