The Quake and Immediate Impact
On August 15, 2026 a magnitude 7.7 earthquake struck off the north-northwest coast of Ende, Flores, at a shallow depth of about 10 km, according to the U.S. Geological Survey and Indonesia’s BMKG. The tremor was felt across Flores and neighboring provinces, triggering landslides that blocked sections of the 700-km Trans-Flores Highway and a brief tsunami warning that was lifted within hours. Rescue agencies reported collapsed homes, public facilities and hospital structures, leaving thousands without shelter.
Background & Seismic Setting
Flores lies on the “Ring of Fire,” where the Australian and Sunda plates converge. The region has suffered deadly events, notably a magnitude 7.5 quake and tsunami in 1992 and the 2018 Sulawesi quake. The 2026 event is the strongest on Flores since those disasters.

On-the-Ground Accounts
Residents described panic-driven evacuations to hills and makeshift tents. In Nangahale village, a mother pleaded for food, medicine and diapers for children. Hospital patients were moved outdoors, and a seminary rector recounted students fleeing a collapsing roof.
Official Statements & Responses
BNPB warned that landslides could isolate remote villages and urged self-evacuation along the northern coast. Cabinet Secretary Teddy Indra Wijaya confirmed deployment of more than 3,500 military and police personnel, three helicopters and a rescue vessel. The East Nusa Tenggara provincial government is considering an emergency declaration to unlock additional resources. Power and communications outages remain major obstacles to relief distribution.
