Luzon, eastern Visayas earthquakes unrelated —PHIVOLCS

The Luzon earthquake on Monday and the one that hit Eastern Samar less than 24 hours after are unrelated, PHIVOLCS officials said on Tuesday.

"'Yung kahapon po local fault po ito dun sa may Zambales-Pampanga area," said Dr. Rhomel Grutas, PHIVOLCS Science Research Specialist.

"Ito po ngayon ay hindi related du'n kasi ito ay trench-related. Subduction zone po siya," he added, saying the Philippine Sea plate moved into the Philippine archipelago.

He added that the movement of the Philippine trench happened 68 kilometers underground.

Its effects were more widespread but had less impact. —NB, GMA News
