Core Event
On the early morning of August 15, 2026, a magnitude 7.7 earthquake struck off the north-west coast of Flores Island in East Nusa Tenggara province. The United States Geological Survey recorded a shallow focus at a depth of 10 km (6 mi) and an epicenter 68 km (42 mi) north-northwest of Ende. Shaking was felt across Flores, West Nusa Tenggara and parts of South Sulawesi, lasting about a minute in many locations.
Background & Context
Indonesia sits on the Pacific “Ring of Fire,” a tectonic belt that generates frequent large earthquakes. The region previously suffered the 1992 magnitude 7.5 quake on Flores, the 2018 magnitude 7.5 quake that generated a deadly tsunami, and the 2004 magnitude 9.1 Sumatra event.
Data & Statistics
- Fatalities: Reported death tolls range from 2 (BBC, NZ Herald) to 47 (PBS, CBS, CBC, NY Times).
- Injuries: Reported injuries vary from 13 to 50.
- Aftershocks: At least 235 aftershocks logged; the largest was magnitude 6.2.
- Housing damage: 157 houses flattened, nearly 200 more damaged.
- Displacement: About 2,000 people evacuated to temporary shelters.
- Tsunami: Waves up to 1.61 m (5.3 ft) recorded in Manggarai regencies; the warning was lifted after roughly three hours.
Official Statements & Responses
Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) issued an initial tsunami warning for East Nusa Tenggara, West Nusa Tenggara, South Sulawesi and Southeast Sulawesi, urging residents inland or to higher ground. The warning was later lifted when sea-level monitoring showed no significant rise.
BNPB chief Suharyanto briefed that at least 38 people had died, 13 were injured, and 2,000 had self-evacuated. He announced the deployment of three helicopters and a rescue vessel for logistics and possible evacuations.
East Nusa Tenggara Police Chief Rudi Darmoko reported severe building collapse and power outages that hampered information flow, noting ongoing communication disruptions as rescue teams continued damage assessments.
On-the-Ground Reports
Residents described panic and mass movement to higher ground.

- Death toll: Sources report 2, 5, 20, 38, 40, and 47 deaths.
- Injury counts: Ranges from 13 to 50.

What’s Next
BNPB and BMKG warned that aftershocks could continue for weeks, urging residents to avoid damaged structures. International assistance has been offered, with the European Commission pledging Copernicus satellite support for search-and-rescue operations. The U.S. Embassy in Jakarta issued an emergency alert advising American travelers to seek secure shelter and avoid coastal areas. Ongoing assessments will determine final casualty figures and the extent of infrastructure restoration.
