A 5.7-magnitude earthquake of tectonic origin, 57 kilometers southeast of Mati, Davao Oriental, shook the province at around 7:58 a.m. Wednesday, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
Phivolcs Director Renato Solidum said the motion of Philippine Fault Zone or the Philippine Trench may have caused the tectonic origin of the earthquake.
The quake is not affiliated with the 7.2-magnitude earthquake that hit Bohol on October 15 but most likely to the East Mindanao Fault Line.
Intensity 5 was felt in Mati and Davao City in Davao Oriental and Toril in Davao Del Sur. Intensity 4 was felt in Caraga, Davao Oriental and Digos City, Don Marcelino, and Malita in Davao Del Sur.
According to the Phivolcs earthquake intensity scale, people indoors and outdoors usually feel the Intensity 5 earthquake through shaking of buildings while an Intensity 4 may cause hanging objects to swing.
Tagum City, Panabo City, Compostela Valley and Mantan-ao in Davao Del Sur felt intensity 3 along with Butuan City, Agusan Del Norte and Kidapawan City, Cotabato.
An Intensity 3 earthquake may cause people to feel dizzy at times with vibrations in the upper floors of a building.
San Francisco in Agusan del Sur, Cotabato City together with General Santos City, Koronadal City and Polomolok in South Cotabato and Alabel, Sarangani felt Intensity 2, which may be felt with objects swinging also.
The magnitude of the earthquake has not caused damages to property and life and will not cause tsunami because of its small range. Aftershocks may also follow after the earthquake, Phivolcs added.
