At least 105 people are dead after an earthquake rocked the Indonesian island of Lombok over the weekend, state media reported Tuesday.

Another 236 people have been injured in the quake, according to the government’s disaster management spokesman Sutopo Purwo Nugroho, who told the Antara News Agency that the casualty numbers could rise as the search continued for survivors.

More than 20,000 people have been displaced since the 6.9-magnitude quake struck Lombok, a popular tourist destination, on Sunday night.

The epicenter of the earthquake was in northern Lombok, a more residential and less developed part of the island. Most of the tourist resorts are located on the southern side of the island.

Most of those killed were struck by falling debris from collapsed buildings, according to Nugroho. Among the many buildings destroyed on Lombok were two homes which housed around 80 underprivileged children.

The roads in the jungle leading to northern Lombok were treacherous and badly damaged in the quake, which is likely to hamper aid efforts, said Endri Susanto, who runs a nongovernmental organization assisting with relief efforts.
