Phivolcs said the earthquake that occurred at around 8:43 a.m. has originated 3 kilometers (km) northwest of Tayum, Abra.

It was initially measured as a magnitude 7.3 quake but Phivolcs later revised it to magnitude 7.0.

Phivolcs said the earthquake was felt at Intensity VII (destructive) in Bucloc and Manabo in Abra.

Meanwhile, it was felt at Intensity VI, as a “very strong” shaking, in Vigan City, Sinait, Bantay, and San Esteban in Ilocos Sur; Laoac in Pangasinan; and Baguio City.

It was also “strong” at Intensity V in Magsingal and San Juan in Ilocos Sur; Alaminos City and Labrador in Pangasinan; Bambang, Nueva Vizcaya; Mexico, Pampanga; Concepcion and Tarlac City in Tarlac province; Manila City; and Malabon City.

It advised the public to stay vigilant as aftershocks may occur due to this earthquake.
