Flores earthquake prompts Indonesia to lift tsunami warning
BMKG recorded a shallow magnitude-7.7 quake northeast of Nagekeo and ended the warning after monitoring the first waves and aftershocks.
The brief
A magnitude-7.7 earthquake struck eastern Indonesia at 4:58 a.m. local time on 15 August, according to BMKG. The quake was 15 kilometers deep and about 30 kilometers northeast of Nagekeo in Flores. BMKG ended the tsunami warning at 7:30 a.m.; reports later said at least 47 people died, roads were blocked and 235 aftershocks followed.
Historical brief for 2026-08-15. Researched and published in September 2026. BMKG located the quake on the Flores Back-Arc Thrust and issued an early warning before ending it at 7:30 a.m. The agency's event record gave the shallow depth and coordinates, which explain why officials treated tsunami risk seriously. The Guardian reported at least 47 deaths, roads and communications blocked by landslides, a wave of about 1.5 meters and 235 aftershocks, including one measured at 6.1.
The first task was to move people from exposed coasts and account for casualties; the second was to avoid a false sense of finality once the warning ended. A warning can be lifted while rescue, aftershock and access risks continue. The record therefore joins technical precision with the human work of reaching villages cut off by the earthquake. Perspectives and divergence score are editorial analysis, not a measured survey of media coverage.
