Magnitude 7.7 earthquake hits Indonesian waters, triggering tsunami alerts

An earthquake with a magnitude of 7.7 struck off the coast of Indonesia near Flores Island early Saturday morning, prompting tsunami warnings from the Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG). The U.S. Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC) reported the magnitude, with EMSC noting a depth of 20 kilometers while USGS indicated 10 kilometers.

The epicenter was located at 8.31 degrees South latitude and 121.35 degrees East longitude. The BMKG issued tsunami alerts for several provinces, including East Nusa Tenggara, West Nusa Tenggara, South Sulawesi, and Southeast Sulawesi. The earthquake was felt across a wide area, with reports of tremors reaching neighboring islands.

Following the initial powerful quake, several aftershocks with magnitudes ranging from 5.5 to 6.1 were recorded in the vicinity of the main tremor, all at a depth of 10 kilometers according to USGS. These subsequent seismic events heightened concerns about potential secondary impacts.

The article notes that Indonesia is situated in the Pacific "Ring of Fire," an area known for its high frequency of earthquakes and volcanic activity. This geological setting makes the region particularly vulnerable to seismic events and their associated hazards, such as tsunamis.
