Magnitude 6.8 Earthquake Strikes Eastern Mindanao, Triggered by Previous Major Seismic Event
A magnitude 6.8 earthquake struck offshore eastern Mindanao in the southern Philippines, resulting from renewed movement along a subducting fracture zone. The tremor, which occurred at 6:23 a.m. local time, was centered 48 kilometers east-northeast of Lingig, Surigao del Sur, at a depth of 25 kilometers. This event follows a magnitude 7.4 earthquake that hit the region eight months earlier, indicating a possible connection between the two seismic occurrences.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the earthquake did not cause significant damage or casualties, although it was followed by six aftershocks ranging in magnitude from 4.8 to 6.2. These aftershocks occurred at shallower depths, further unsettling the region.
