A powerful magnitude 7.7 earthquake struck eastern Indonesia on Saturday, August 15, 2026, killing at least 38 people, damaging buildings and forcing thousands of residents to leave affected areas.
The earthquake hit near Flores in East Nusa Tenggara province, with some of the worst damage reported across communities on the island. Rescue teams are continuing to search affected areas while authorities assess damage and work to reach locations cut off by landslides and communication problems.
Indonesia’s Meteorology, Climatology and Geophysical Agency, BMKG, recorded the earthquake at magnitude 7.7, with its centre about 30 kilometres northeast of Mbay in Nagekeo, East Nusa Tenggara. BMKG reported a depth of 15 kilometres.

Where Did the Magnitude 7.7 Earthquake Strike?
According to official BMKG information, the earthquake occurred at 8.41 degrees south latitude and 121.39 degrees east longitude, approximately 30 kilometres northeast of Mbay in Nagekeo.
The quake affected parts of Flores and surrounding areas in eastern Indonesia. AP reported damage in several areas, while landslides and damaged roads made access difficult in some locations.
Reuters reported that Nagekeo Regency was particularly difficult to access because of landslides and communication outages.
At Least 38 People Confirmed Dead
The latest reports say at least 38 people have died, while others have been injured or remain missing.
Reuters reported that 20 deaths were recorded in Maumere, the largest town in Sikka Regency on Flores Island. Rescue teams continued working across affected communities as authorities gathered more information about the scale of the disaster.
AP also reported significant damage from the earthquake, including building collapses, landslides and power outages.
Because the situation is developing, the confirmed death toll may be revised as rescue operations continue.
More Than 2,000 People Displaced
The earthquake forced more than 2,000 people to evacuate or leave affected communities, according to Reuters.
Infrastructure damage, power outages and disrupted communications have complicated emergency operations in some locations.
Authorities and rescue teams are working to reach communities where damaged roads and landslides have made travel difficult.
Tsunami Warning Issued After Indonesia Earthquake
The magnitude 7.7 earthquake initially triggered a tsunami warning.
Official BMKG monitoring detected tsunami waves at several locations after the earthquake.
Among the measurements reported by BMKG were:
| Monitoring Location | Recorded Wave |
|---|---|
| Maurole, Ende | 0.94 metres |
| Pelabuhan Kewapante, Sikka | 0.38 metres |
| Labuan Bajo | 0.36 metres |
| Flores Timur | 0.25 metres |
| Sikka | 0.19 metres |
| Dompu | 0.17 metres |
| Bakalang, Alor | 0.14 metres |
These are official observed measurements published by BMKG, rather than estimates.
The tsunami warning was later lifted after authorities continued monitoring sea levels.
Buildings and Infrastructure Damaged
The earthquake caused damage across several parts of the affected region.
Reports described damaged or collapsed buildings, landslides, power outages and transportation disruption. Some roads were blocked, making it harder for emergency teams to reach isolated communities.
Aftershocks also followed the main earthquake, adding to concerns for people in already affected areas.
Rescue Operations Continue
Emergency teams are continuing search, rescue and relief operations.
AP reported that helicopters and a vessel were supporting response efforts, while authorities continued assessing damage and trying to reach communities affected by transportation and communication disruptions.
The final scale of the damage may take time to establish because Flores contains mountainous areas where landslides can make road access difficult after a major earthquake.
Why Does Indonesia Experience Powerful Earthquakes?
Indonesia is one of the world’s most earthquake-prone countries because of its location along the Pacific Ring of Fire, a highly active seismic region where several tectonic plates interact.
As a result, Indonesia frequently experiences earthquakes and volcanic activity.
This does not mean every major earthquake causes a tsunami. Authorities assess factors including the earthquake’s location, depth and movement before determining the tsunami risk.
What Happens Next?
The immediate priority is reaching affected communities, assisting displaced residents and determining the full extent of damage.
Authorities are also monitoring aftershocks following the magnitude 7.7 earthquake.
The number of confirmed casualties may change as rescuers reach areas that have been difficult to access.
