MANILA (UPDATE) – A magnitude 6.0 earthquake struck off Davao Oriental province on Thursday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
The tectonic tremor struck at around 11:53 a.m. Its epicenter was located 31 kilometers southeast of Tarragona town, Phivolcs said.
The earthquake was felt at Intensity 4 in Mati City and Intensity 3 in Davao and Cagayan de Oro cities, the office said.
Phivolcs said Intensity 4 is "generally felt by most people indoors and outdoors. Many sleeping people are awakened. Some are frightened, some run outdoors."
Intensity 3, meanwhile, causes vibrations that may be felt like the passing of a light truck and can make hanging objects swing moderately, said Phivolcs.
There has been no reports of damage in Mati City so far, said disaster officer Charlemagne Bagasol.
Phivolcs originally reported the magnitude of Thursday's quake at 5.5, but later upgraded it to 6.0.
The tremor is not strong enough to cause tsunamis, but may trigger aftershocks, Phivolcs science research assistant Tom Simborio said in a phone interview with ABS-CBN News online.
