Powerful 7.7 Magnitude Earthquake Strikes Flores, Indonesia

Powerful 7.7 Magnitude Earthquake Strikes Flores, Indonesia: Tsunami Warning Issued, At Least Two Confirmed Dead

A major earthquake has rocked eastern Indonesia, sending shockwaves through communities on Flores Island and prompting urgent safety measures across multiple provinces.

On August 14, 2026, at 21:58:21 UTC (approximately 5:58 a.m. local time on August 15), a magnitude 7.7 earthquake struck 68 kilometers north-northwest of Ende in East Nusa Tenggara province. The U.S. Geological Survey confirmed the shallow quake occurred at a depth of 10 kilometers as the result of reverse faulting. Strong aftershocks followed, including magnitudes of 5.9, 5.6, and 6.1.

Immediate Impact and Response

Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) quickly issued a tsunami warning for parts of East Nusa Tenggara, West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi. Residents along affected coastlines were urged to move to higher ground and stay away from beaches and riverbanks. The warning was later lifted after monitoring showed no significant dangerous sea-level changes, though small waves of 19 to 30 centimeters were detected in some areas.

Damage reports emerged rapidly. Buildings and homes sustained structural harm, including a collapsed waiting room at the port terminal in Maumere. Hospitals evacuated patients outdoors, and churches reported roof collapses. The USGS estimated that approximately 1.5 million people experienced strong to severe shaking, with around 500,000 exposed to very strong or severe levels capable of moderate to serious damage.

Community Experiences and Ongoing Monitoring

Residents described intense shaking that sent people fleeing into the streets. One hospital worker in the area reported patients and staff rushing outside as walls cracked. Videos circulating online captured collapsing structures and panicked evacuations in places like Maumere and surrounding villages.
