An earthquake measuring 5.4-magnitude has occurred off the coast of Davao Oriental early Saturday morning, Nov. 20, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Phivolcs detected the earthquake at around 4:13 a.m.
Its epicenter was traced 118 kilometers (km) southeast of Tarragona, Davao Oriental at a depth of 39 km.
Phivolcs said there was no reported intensity but aftershocks may occur due to this earthquake.
Before the 5.4-magnitude earthquake, Phivolcs also recorded a 5.2-magnitude tremor off the coast of Davao Oriental at around 4:08 a.m.
The epicenter of the 5.2-magnitude quake was traced 83 km southeast of Tarragona, Davao Oriental at a shallow depth of only 1 km.
There was also no reported intensity from this particular earthquake.
Phivolcs said the earthquakes were tectonic in origin, which means they were caused by the movement of an active fault near the area.
