A magnitude 7.7 earthquake struck the Flores island region of eastern Indonesia in the early hours of Saturday, August 15, according to the United States Geological Survey (USGS). Indonesia's meteorological agency BMKG issued a tsunami warning two minutes and 16 seconds after the earthquake, according to Antara News.
The earthquake falls within the Pacific Ring of Fire, the same belt of volcanoes and fault lines that runs along the western coast of the Americas and includes Mexico's Pacific coastline. Indonesia, an archipelago of more than 17,000 islands, is prone to earthquakes and volcanic activity due to its position on the Ring of Fire, according to NBC News. The warning issued in just over two minutes, alongside evacuations to higher ground in the port city of Maumere, provides a real-time benchmark for the early warning systems that other seismically active countries, including Mexico, operate along their coasts. The earthquake came days after a magnitude 7.4 event off western Colombia, adding to a pattern of recent seismic activity across the Pacific basin, according to NBC News.
On Saturday, the head of the National Disaster Management Agency (BNPB) reported 38 deaths, two seriously injured, and 11 with minor injuries, along with approximately 2,000 people evacuated to safety, according to NBC News. Earlier, rescue workers at the port of Maumere had found 20 dead, six injured, and two people trapped under rubble, according to Fathur Rahman, head of the city's rescue agency. The initial alert covered parts of the provinces of East and West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi, according to NBC News; authorities urged residents to move away from beaches and rivers. The earthquake struck at a depth of 15 kilometers, according to Antara News, and was followed by aftershocks as rescue teams searched for survivors, Al Jazeera reported; several hospitals in the area moved their equipment outdoors as a precautionary measure, according to NBC News.
Australia's Tsunami Warning Centre indicated the earthquake posed no threat to its territory, while the search for survivors continued amid aftershocks in hard-to-reach areas, according to NBC News and Al Jazeera. For seismically exposed coastlines across the region, including Mexico's, the two-minute window between earthquake and warning defines the time available to evacuate.
