2nd earthquake hits Indonesia following powerful magnitude 7.7 quake
Indonesia Faces Second Major Quake After Deadly 7.7 Magnitude Tremor
Tyunews.com – A powerful magnitude 7.7 earthquake rattled eastern Indonesia early on August 15, 2026, with a significant aftershock of magnitude 6.9 arriving just hours later. The U.S. Geological Survey confirmed both events occurred off the coast of the country's eastern region.
According to the National Disaster Management Agency (BNPB), the seismic activity has claimed at least 38 lives. Emergency responders, including personnel from the Indonesian National Armed Forces, have been working to evacuate affected populations and evaluate structural damage. Officials reported that several buildings collapsed during the tremors, while hundreds of residents fled to higher ground due to concerns about potential tsunamis.
Tsunami Warnings and Evacuations
Indonesia's Meteorology, Climatology and Geophysics Agency initially issued alerts urging people to avoid coastal areas and evacuate immediately. These warnings were subsequently lifted, though many residents had already taken precautionary measures. The disaster management agency noted that approximately 2,000 inhabitants of the Nagekeo Regency on Flores island "carried out self-evacuation as a precautionary measure after the earthquake and due to the early warning of a tsunami."
The earthquake's epicenter sat roughly 60 kilometers north-northwest of Ende at a depth of about 10 kilometers, according to USGS data. The tremor was strongly felt throughout the East Nusa Tenggara province, where it struck shortly before 5 a.m. local time.
Casualties and Ongoing Response
Beyond the fatalities, at least six individuals sustained injuries and two others remain unaccounted for, according to the Associated Press. Photographs circulating from the region revealed significant damage to structures in areas including Maumere and Ruteng.
Seismologists documented several strong aftershocks in the vicinity, including tremors measuring 6.1 and 5.9 in magnitude, both located north of Ende. This remains a developing situation, and authorities continue to monitor conditions closely.
