The Philippine Institute of Volcanology and Seismology (Phivolcs) on Saturday, July 6, recorded a 5.3-magnitude quake that struck Cagayan.
Based on Phivolcs’ data, the earthquake struck at 6:29 p.m., with an epicenter 117 kilometers (km) northwest of Calayan, Cagayan.
It noted that the quake, tectonic in origin, was due to the sudden movement of the earth’s crust and had a depth of focus of 174 km.
However, Phivolcs expected an “aftershock” but “no damages” due to this earthquake.
