Magnitude 7.8 quake hits southern Philippines; tsunami warnings issued for Philippines and Indonesia

Tsunami warnings have been issued after a powerful magnitude 7.8 earthquake struck off Mindanao in the southern Philippines on Monday. The German Research Centre for Geosciences (GFZ) reported the seismic event, initially estimating its magnitude at 8.2 before revising it. The quake's epicenter was located at a depth of 10 kilometers (6.2 miles). Both the geophysics agencies of the Philippines (Phivolcs) and neighboring Indonesia (BMKG) issued tsunami warnings following the tremor. Phivolcs reported the earthquake at a magnitude of 7.0, warning of potential damage and tsunami waves exceeding one meter, which could persist for several hours. Indonesia's BMKG provided a magnitude estimate of 7.7. There were no immediate reports of major damage in either country. However, in Alabel town, Sarangani province, Philippines, the police building sustained cracks immediately after the quake, which occurred during a flag-raising ceremony. Police chief Benjie Ancheta stated there were no immediate casualty reports, though some individuals fainted due to the strong tremor, describing it as the "strongest earthquake we've experienced." Witnesses in Manado, a northern city in Indonesia, also reported feeling a very strong tremor. The Philippines and Indonesia are situated within the seismically active "Pacific Ring of Fire," a belt known for its frequent earthquakes and volcanic activity, stretching from South America to the Russian Far East.
