MANILA, Philippines – A magnitude 4.8 earthquake rattled parts of Luzon, including Metro Manila, Thursday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its bulletin, Phivolcs said the quake occurred at 6:46 a.m. with its epicenter located some 15 kilometers southeast of Iba, Zambales.
The tremor, which was tectonic in origin, had a shallow depth of 23 kilometers.
Phivolcs said the quake was felt at Intensity 4 in the towns of Iba and San Felipe in Zambales and Intensity 3 in Masinloc, Botolan, and Olongapo City in Zambales; Clark in Pampanga; and Tarlac City in Tarlac.
It was also felt at Intensity 2 in Santa Cruz, Zambales and Dinalupihan in Bataan, while the cities of Makati and Quezon in Metro Manila felt the tremor at Intensity 1.
Phivolcs’ seismometers recorded Intensity 3 in Iba, Zambales and Clark, Pampanga and Intensity 1 in Dagupan City, Pangasinan.
Science research assistant Benz Rodriguez of the Phivolcs’ Earthquake Monitoring Division said there were no reported casualties and damages from the temblor and aftershocks were not expected.
Rodriguez said movements related to the Manila Trench possibly triggered the tremor.
The Manila Trench is a deep underwater trench in the west of the country that runs from Northern Luzon to Mindoro.
