A magnitude 4.0 earthquake hit the waters off Hinatuan in Surigao del Sur on Wednesday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its latest earthquake bulletin, Phivolcs said the epicenter of the offshore quake was traced 36 kilometers northeast of Hinatuan town at 10:25 a.m.
The tremor had a depth of 18 kilometers and was tectonic in origin which was caused by ground shaking primarily due to the sudden movement in the Earth's plates, Phivolcs added.
The state seismology bureau said Instrumental Intensity I was recorded in Bislig City also in Surigao del Sur during the quake.
Phivolcs said there were no immediate reports of damage or injury from the tremor, while aftershocks are also not expected.
