A 6.2 magnitude earthquake hit off the coast of Mindanao in the southern Philippines on Monday, striking the same region where a catastrophic seismic event claimed dozens of lives just one week prior.
Data from the U.S. Geological Survey (USGS) indicated that the tremor occurred at 5:18 p.m. at a depth of 112 kilometers (69.5 miles).
Despite the substantial magnitude of the tectonic event, the national seismology agency did not issue a tsunami warning.
Kaiser Cadiz of the Davao Oriental provincial disaster office characterized the tremor as a “moderate” earthquake, stating that there were no immediate reports of structural destruction or casualties.
”Our priority now is to monitor the coast to determine if there are indications the water had receded (an indicator of an impending tsunami),” Cadiz said.
Cadiz further noted that surveillance teams had not detected any coastal irregularities.
The southern region continues to endure the aftermath of a devastating 7.8 magnitude earthquake that struck Mindanao on June 8. That powerful disaster flattened infrastructure, caused extensive landslides, and triggered regional tsunami warnings.
On Monday, national disaster authorities raised the official death toll from the June 8 disaster to 65, while at least 36 people remain unaccounted for.
The physical impact of the initial disaster was severe. The Department of Environment and Natural Resources reported that the seabed in a coastal locality was pushed upward by two meters, exposing coral reefs and extending the shoreline by up to 200 meters.
Positioned along the Pacific “Ring of Fire”—a seismically volatile zone spanning from Japan through Southeast Asia—the Philippines experiences near-daily earthquakes. The southern coast of Mindanao is particularly vulnerable due to its proximity to the Cotabato Trench, a major source of frequent seismic swarms.
This latest event adds to a challenging period for eastern Mindanao, which also experienced two major earthquakes of 7.4 and 6.7 magnitude, resulting in at least eight fatalities.
