Core Event
On the early morning of August 15, 2026, a magnitude 7.7 earthquake struck off the coast of Flores Island in Indonesia’s East Nusa Tenggara province. The United States Geological Survey placed the epicentre about 68 km north-northwest of Ende at a depth of roughly 10 km. The tremor was felt across the island and in neighboring West Nusa Tenggara and South Sulawesi. A tsunami warning was issued and later lifted after waves of less than one metre were recorded. Landslides blocked sections of the Trans-Flores Highway, and collapsed buildings left thousands displaced.
Background & Context
Indonesia sits on the Pacific “Ring of Fire,” a tectonic belt that generates frequent earthquakes and volcanic eruptions. Flores has experienced several of the nation’s deadliest disasters, including a 1992 quake-tsunami that killed about 2,500 people and the 2004 magnitude 9.1 Sumatra quake that generated a tsunami killing roughly 230,000 across a dozen countries.
Data & Statistics
- Casualties: Reported deaths range from 38 to 53. The National Disaster Management Agency (BNPB) cited 36 serious injuries and 77 minor injuries on August 15, 2026.
- Housing damage: More than 900 homes were destroyed and about 450 damaged.
- Public infrastructure: 167 public facilities—including schools, health centres and churches—were reported damaged.
- Displacement: Approximately 5,000 people were evacuated to temporary shelters.
- Aftershocks: At least 341 aftershocks were recorded; 46 were felt by residents.
Official Statements & Responses
Deputy Health Minister Benjamin Paulus Octavianus said the quake caused 36 serious and 77 minor injuries. Cabinet Secretary Teddy Indra Wijaya announced the deployment of more than 3,500 military and police personnel and noted an emergency declaration was being considered. Lieutenant General Suharyanto, head of BNPB, said restoring electricity, communications and delivering aid to isolated villages were top priorities. The agency reported that 50,000 aid packages weighing 275 tonnes had been dispatched.
On-the-Ground Reports
Residents described panic and fear of aftershocks. Umri, a resident of Nangahale village, pleaded for food, drink, medicines and diapers for children. Simon Subandi, deputy regent of Sikka, noted that “almost all of Sikka’s residents didn’t dare stay indoors, so they slept on a porch or a tent outside.” In Talibura village, 51-year-old Nona recalled, “The quake was massive; the shock was so strong.”
Conflicting Reports & Gaps
- Death toll: Sources list 38, 47, 51 and 53 fatalities.
- Aftershock count: Reported figures range from 235 to 995, with only 46 felt by the public.
- Missing persons: No definitive count has been released; agencies say most missing are likely trapped under rubble.

Why It Matters
The quake underscores the vulnerability of Indonesia’s densely populated, mountainous islands to shallow, high-magnitude events. Disruption of the Trans-Flores Highway hampers relief logistics and threatens the tourism economy centered on Komodo National Park. The scale of displacement and infrastructure loss highlights gaps in emergency housing, power restoration and communication networks.
What’s Next
Authorities expect aftershocks to continue for several weeks, and the emergency declaration being processed will allow additional funding for reconstruction. Ongoing air-lift and sea-borne aid deliveries aim to restore electricity, reopen blocked roads and provide food, water and medical supplies to the roughly 5,000 evacuees still in temporary shelters.
