A 4.0-magnitude earthquake struck parts of Leyte province on Wednesday morning, Oct. 20, said the Philippine Institute of Volcanology and Seismology (Phivolcs).
Phivolcs traced the epicenter of the earthquake at 8 kilometers (km) northeast of Albuera, Leyte at 6:12 a.m.
The earthquake was "moderately strong" at Intensity IV in Albuera and Ormoc City, Leyte.
It was "weak" at Intensity III in Baybay City, Burauen, La Paz, and Dulag, Leyte, while it was "slightly felt" at Intensity II in Pastrana, Julita, Tabontabon, Javier, and Abuyog, Leyte
Phivolcs' instruments also measured the tremor at Intensity IV in Ormoc City, Intensity III in Abuyog, City, Baybay, and Dulag, Leyte; Intensity II in Palo and Hilongos, Leyte; and Intensity I in Sogod, Southern Leyte.
A 3.7-magnitude quake followed at 6:15 a.m.
It was felt at Intensity III in Albuera, Leyte and Ormoc City and Intensity II in Burauen, La Paz, and Dulag, Leyte.
Phivolcs said the earthquakes were tectonic in origin, which means they were caused by the movement of an active fault near the area.
However, Phivolcs does not expect damage to property or aftershocks due to these earthquakes.
