RUTENG, Indonesia — Rescue teams in eastern Indonesia recovered six more bodies Sunday, a day after a magnitude 7.7 earthquake, raising the death toll to 53, authorities said, as many of the thousands of displaced people spent the night outdoors in fear of aftershocks.

Rescuers dug through debris looking for anyone buried beneath landslides triggered by the quake across six regencies on Flores, a predominantly Catholic island in the Muslim-majority country. They focused on three regencies that remained inaccessible: hardest-hit Manggarai, East Manggarai and Nagekeo.

“We have cleared most landslides and reopened roads to previously isolated villages, although communication disruptions and power outages continue to hamper search efforts,” said Fathur Rahman, head of the search-and-rescue office in Maumere, the capital of Sikka regency.

More than 900 homes were destroyed and 450 more damaged in East Nusa Tenggara province, forcing about 5,000 people into temporary shelters. At least 241 homes were damaged in the Flores region alone, said Abdul Muhari, the National Disaster Management Agency’s chief for disaster prevention.

The quake occurred at a depth of 10 kilometers (6 miles) shortly before 6 a.m. Saturday, the U.S. Geological Survey said. Residents fled in panic as tsunami warnings were issued and later lifted.

Authorities have since recorded at least 995 aftershocks, but only 46 were felt by residents, Muhari said, adding that 135 people were injured.

Many residents at Labuan Bajo, the gateway to Komodo National Park, one of Indonesia’s best-known tourist destinations, spent the night outside because of the aftershocks.

“The shaking was terrifying, so intense that my house nearly collapsed,” said farmer Anastasia Imad, speaking from a makeshift green tent beside her damaged home. “We feared the aftershocks would bring it down on us while we slept.”

Landslides blocked sections of the Trans-Flores Highway, a roughly 700-kilometer (435-mile) road linking communities across the mountainous island.

Meanwhile, relief workers distributed rice, ready-to-eat meals, drinking water, blankets and medicine, while emergency shelters were set up for displaced residents. Authorities said restoring electricity and communications, as well as delivering aid to remote villages isolated by landslides, were among the biggest challenges.

Indonesia, an archipelago of more than 17,000 islands, is prone to earthquakes and volcanic eruptions because of its location on the Pacific “Ring of Fire,” a horseshoe-shaped arc of seismic faults and volcanoes.

Flores has experienced some of the country’s deadliest disasters. A powerful earthquake and tsunami in 1992 killed about 2,500 people on the island.

In 2018, a magnitude 7.5 earthquake triggered a tsunami on the island of Sulawesi that killed more than 4,400 people. In 2004, a magnitude 9.1 quake off Sumatra unleashed a tsunami that killed about 230,000 people in a dozen countries.
