A magnitude-7.7 earthquake tore through Indonesia's Flores Island before dawn on Saturday, killing at least 47 people, injuring dozens more and setting off landslides that have buried roads and cut off remote villages across six districts, disaster officials said. Rescuers warned the toll was likely to rise as they struggled, more than a day later, to reach communities isolated by the damage.
The quake struck at about 5:58 a.m. local time, with its epicenter roughly 68 kilometers north-northwest of Ende, the largest town in East Nusa Tenggara province, at a shallow depth of about 10 kilometers, according to the US Geological Survey. More than 230 aftershocks have since rattled the island, the strongest measuring magnitude 6.2. A tsunami warning was issued within minutes and lifted about two and a half hours later, after monitoring stations detected no significant rise in sea level.
Indonesia's National Disaster Management Agency, known as BNPB, said 346 houses were damaged, 157 of them severely, along with 87 schools, 18 health clinics, six government offices and five houses of worship. More than half a million people are believed to have experienced very strong shaking, the USGS estimated, with moderate tremors felt as far away as Bali and Sumbawa.
Villages cut off as the toll climbs
The worst destruction has been reported in Nagekeo and Ende regencies, where landslides triggered by the shaking have blocked roads and severed phone lines to several mountain villages. Authorities said they had not yet been able to make contact with some settlements, raising fears the confirmed toll of 47 will grow once access is restored. Around 2,000 residents fled their homes for temporary shelters, many too frightened by the relentless aftershocks to return.

Geologists have also flagged secondary hazards, including ground cracks and liquefaction — a phenomenon in which saturated soil temporarily behaves like a liquid — after reports of water surfacing unexpectedly in the Waekokak-Mbay area. Indonesia's Geological Agency said it was investigating.
A coastline that has broken before
Flores sits along the Flores back-arc thrust fault, part of the seismically volatile Pacific Ring of Fire, and this weekend's rupture struck almost the same stretch of coastline devastated in December 1992, when a quake and the tsunami it triggered killed more than 2,500 people on the island. That history has shaped both the government's rapid tsunami alert and residents' evident dread as the ground kept shaking through Saturday.
BNPB chief Lt. Gen. Suharyanto said the agency had mobilized roughly 50,000 aid packages, totaling some 275 tonnes of supplies, dispatching them by Indonesian Air Force aircraft; about 10,500 had reached affected areas by Saturday evening. Three helicopters and a rescue vessel have been deployed to reach coastal areas that roads can no longer serve.
With aftershocks continuing and forecasters warning of more rain in the coming days, officials said the priority now is reaching cut-off villages before landslide-damaged slopes give way further. A fuller accounting of the dead and missing is not expected until rescue teams complete door-to-door searches across all six affected regencies.
