Magnitude 6 quake strikes off Davao Oriental
MANILA, Philippines (3rd UPDATE)– A magnitude 6 earthquake struck off Mati, Davao Oriental Friday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Phivolcs said the earthquake occurred at 9:14 a.m.
Its epicenter was located 162 kilometers southeast of Mati.
Phivolcs initially reported that the earthquake had a magnitude of 5.9 and had occurred 145 kilometers southeast of Mati.
It issued the revised report at 1:59 p.m.
The following intensities were felt:
- Intensity IV (moderately strong) - General Santos City; Don Marcelino, Davao del Sur
- Intensity III (weak) - Davao City; Mati and Manay, Davao Oriental; Digos City and Malita, Davao del Sur
- Intensity II (slightly felt) - Tagum City; Carmen, Davao del Norte; Sta. Cruz, Davao del Sur ; Koronadal, South Cotabato
The earthquake was tectonic in origin. It had a depth of 46 kilometers.
Phivolcs said aftershocks are expected from the earthquake.
However, Phivolcs Director Renato Solidum said the tremors and the aftershocks that the earthquake will produce would not be destructive.
“The groundshaking intensity is not destructive. The quake is in the sea so some of these aftershocks might not be felt by the people,” Solidum told ANC.
The United States Geological Survey, meanwhile, reported that the earthquake struck with a magnitude of 5.5.
Solidum explained that the disparity in the magnitude measurement between the two agencies is due to the the difference in the formula they use.
