Two earthquakes rocked Banganga, Davao Oriental early Thursday morning, but no damage has so far been reported.
The Philippine Institute of Volcanology and Seismology (Phivolcs) said a 5.1 magnitude quake hit Davao Oriental at 5:39 a.m. with a depth of four kilometers and a location of 63 kilometers northeast in the municipality of Baganga.
Of tectonic origin, the tremor was caused by the sudden movement along faults and plate boundaries, Phivolcs said.
Intensity 1 was recorded in Bislig City, and Surigao del Sur, along with Nabunturan, Davao de Oro.
A tremor of magnitude 5 quake was recorded Thursday at 4:19 a.m. some 70 kilometers northeast of Baganga, Davao Oriental.
Initially, it was recorded with a magnitude of 5.3, but Phivolcs later downgraded it to magnitude 5.
It was felt at intensity 3 in Lingig, Surigao del Sur, and intensity 2 in Bislig City, Surigao del Sur.
Instrumental intensity 1 was also felt in Tandag City, Surigao del Sur and Cabadbaran City, Agusan del Norte.
