6.7 magnitude earthquake hit Aceh and North Sumatra early in the morning on Tuesday, killing two people, injuring several others and destroying dozens of houses in Subulussalam, Aceh and surrounding regions.

One of the two people killed was a 10-year old boy, identified as Riyanda Syahputra. The epicenter of the quake, which occurred at 12:55 a.m. local time, was in Singkil, South Aceh.

Subulussalam Mayor Meurah Sakti said his city was the worst hit area as it was closest to the center of the earthquake. According to data from the municipal administration, at least 20 houses, 11 school buildings, five mosques and three community health centers were damaged by the earthquake.

“We are continuing to conduct an inventory on the data regarding the damage caused,” Meurah Sakti told The Jakarta Post via telephone on Tuesday.

Subulussalam social service agency head Mahdi said that Sultan Daulat was the worst-hit district in the municipality, in which dozens of houses were either severely damaged or had suffered subsidence.

Sabaruddin from Singkil said that people in the region are still traumatized following the earthquake. Those living in coastal areas, he said, preferred to stay away from the coast over fear of aftershocks that might have the potential to cause a tsunami.

Singkil Police chief Adj. Sr. Comr. Helmi Kwarta said people were indeed traumatized and their activities at one point ceased because of a total blackout.

“But many have returned home now as the electricity is restored and activities are returning to normal again,” he said.

Meanwhile, in North Sumatra, the earthquake hit Pakpak Bharat regency, damaging a Catholic church, a mosque, the regent’s office and the vice regent’s official residence. In Humbang Hasundutan regency the earthquake damaged a church and a subdistrict hall.

The Medan office of the Meteorology, Climatology and Geophysics Agency reported that the 6.7 magnitude earthquake could be felt across Aceh province, North Sumatra and West Sumatra.

The agency’s head of data and information, Hendra Suwarta, said the 78 kilometer-deep earthquake did not have the potential to trigger a tsunami.

The earthquake, according to Hendra, was caused by the activity of the Sumatra fault, due to a clash between the Indo-Australia and Euro-Asia plates.

However, he reminded people that to remain cautious because, so far, no aftershocks have been detected following the earthquake.
