Mild earthquakes rocked the provinces of Ilocos Norte and Agusan del Norte before dawn yesterday, based on the latest records of the Philippine Institute of Volcanology and Seismology (Phivolcs).
The tremors were tectonic in origin and neither aftershocks nor damage to properties were expected from both seismic events.
Phivolcs said a magnitude-3.5 offshore quake struck Ilocos Norte at 12:56 a.m. on Friday with the epicenter located 37 kilometers northeast of Pagudpud.
It emanated from a depth of 22 kilometers and Instrumental Intensity II was recorded in Pasuquin.
