Pinatubo as Aetas at Barangay Inararo in Porac town, Pampanga province, reported seeing steam explosions near the volcano. According Phivolcs, the epicenter of Monday’s quake was in Castillejos town in Zambales. Science and Technology Secretary Fortunato de la Peña said the Zambales quake was not caused by a volcanic activity. De la Peña, who briefed President Rodrigo Duterte here on Monday, said there was a low probability that another quake with a higher magnitude would occur from the same source. The tsunami threat for Zambales and Pampanga would come from the movement of the Manila Trench, located west of [these] provinces,” De la Peña said.
