A man was killed and two women were injured Tuesday in the magnitude-5.6 earthquake that rocked Aceh province, located on the northern tip of Indonesia's Sumatra island, media reports said.

"The fatality was a man who died from a heart attack," the Jakarta Globe newspaper reported, citing National Disaster Response Agency officials in the city of Pidie.

The two women were seriously injured when their house in the Tangse district of Pidie collapsed.

The temblor caused extensive damage to 39 dwellings and less severe damage to 60 other structures, the National Disaster Response Agency said.

The earthquake's epicenter was at a depth of 10 kilometers (6.2 miles) and some 16 kilometers (9.9 miles) southwest of Aceh Besar regency, the Indonesian seismology service said.

Indonesia is located in the "Pacific Ring of Fire," a region of frequent earthquakes and volcanic activity.

The region is rocked by about 7,000 earthquakes annually, the majority of them moderate.

A powerful earthquake triggered a tsunami in December 2004 off Sumatra, killing more than 226,000 people in a dozen countries located on the Indian Ocean. EFE
