7.7-magnitude quake kills two in eastern Indonesia; tsunami warning lifted

A powerful earthquake tore through eastern Indonesia before dawn on August 15, killing at least two people and sending hundreds of residents scrambling toward higher ground. The 7.7-magnitude quake struck off the northern coast of Flores Island, roughly 68 kilometers northwest of the town of Ende, at a shallow depth of between 10 and 15 kilometers—the kind of proximity to the surface that amplifies the shaking felt on land. Indonesia's geophysics agency recorded the initial jolt at 4:58 in the morning, and it was violent enough that people felt it strongly for about a minute across the region, from Nagekeo to Bima.

Within minutes, disaster officials were urging evacuation. Abdul Muhari, speaking for Indonesia's national disaster agency, told residents along Flores's northern and southern coasts to leave immediately—either by moving more than two kilometers inland or climbing to hills at least ten meters high. The warning carried weight: a 6.1-magnitude aftershock followed the initial quake, and authorities had issued a tsunami alert with waves potentially reaching between half a meter and three meters high. Residents in Maumere, the main town in the area about 2,400 kilometers from Jakarta, could see the sea receding, a telltale sign that a wave might be coming.

The evacuation was chaotic and immediate. Lukas Lotar, a 31-year-old hospital customer service worker, described the moment the ground began to move. "Suddenly it started to shake and I panicked," he said. "Patients also fled the hospital, the jolt was big. I saw some walls were cracked." Video footage verified by Reuters showed a building at the Maumere port collapsing into dust and rubble as people screamed and ran through the streets. Hundreds of residents in nearby Nagekeo regency were captured on Indonesian television moving away from the coast, some heading to higher ground, others simply running from their homes.

By 8:42 in the morning, Indonesia's meteorology agency lifted the tsunami warning. Australia's tsunami warning centre confirmed there was no threat to the Australian mainland or its territories. But the full scope of the damage remained unclear. Berton Suar Pelita Panjaitan, a spokesman for Indonesia's disaster agency, told reporters in Jakarta that two deaths had been confirmed—a man and a woman—but cautioned that the final casualty count and assessment of structural damage would come only after data were fully compiled. Hospital staff were still moving patients outside facilities as a precaution.

Indonesia sits along the Pacific Ring of Fire, an arc of intense seismic activity that makes earthquakes a recurring fact of life across the archipelago. The country's recent history is scarred by catastrophic tremors. In 2004, a 9.1-magnitude earthquake off Sumatra's coast triggered a tsunami that killed roughly 220,000 people across the region, with about 170,000 of those deaths in Indonesia itself—one of the deadliest natural disasters ever recorded. In 2018, a 7.5-magnitude quake and tsunami in Palu on Sulawesi killed more than 4,300 people. That same year, a powerful tremor shook Lombok, killing more than 550 across the island and neighboring Sumbawa. Against that backdrop, the August 15 quake off Flores, though serious and deadly, was being treated as a contained event—but one whose full human cost was still being tallied.
