7.7 magnitude earthquake hits Indonesia

A powerful magnitude 7.7 earthquake struck off the coast of eastern Indonesia early Saturday morning, killing at least 20 people and triggering widespread panic across Flores island. The shallow undersea tremor, recorded at a depth of 10 kilometers by the U.S. Geological Survey, hit at approximately 5:58 a.m. local time with an epicenter located 68 kilometers north-northwest of Ende in East Nusa Tenggara province. Residents described chaotic scenes as the violent shaking struck, with one local university lecturer comparing the motion to being on a trampoline as household items tumbled and families rushed outdoors into the early morning light.

Indonesia's Meteorology, Climatology, and Geophysics Agency promptly issued a tsunami warning for several provinces, including East and West Nusa Tenggara as well as South and Southeast Sulawesi. Coastal residents in areas like Nagekeo raced toward higher ground after witnessing the sea retreat, a classic natural warning sign of an approaching tsunami. Although authorities eventually lifted the tsunami alert, danger persisted as dozens of aftershocks rattled the region, measuring up to magnitude 6.1. The ongoing tremors complicated recovery work, forcing rescue personnel and frightened civilians to remain outdoors, with hospital patients treated under emergency tents and residents cooking on makeshift stoves in the open air.

Structural damage across the largely rural island was significant. Officials and witnesses reported cracked walls, collapsed roofs at institutions such as St. Peter Major Seminary in Sikka, and a partially collapsed waiting room at the port terminal in Maumere. Rescue official Fathur Rahman confirmed that search efforts quickly pivoted toward locating individuals trapped under rubble, though landslides triggered by the seismic activity cut off vital access roads and slowed down emergency response teams. At least two people were reported trapped alive, while others suffered injuries, including a priest who broke his leg jumping from a second-floor building during the initial violent jolt.

The disaster serves as a grim reminder of the region's extreme seismic vulnerability. Situated within the Pacific "Ring of Fire," Indonesia experiences frequent tectonic activity driven by shifting fault lines and volcanic arcs. While Saturday's earthquake occurred on a weekend morning when schools and universities were largely empty—averting a far higher casualty toll—authorities continue to urge citizens to stay away from compromised structures as aftershocks threaten to bring down weakened buildings.
