MANILA, Philippines (UPDATE) - A strong magnitude 6 earthquake struck off Zambales province in northern Philippines on Wednesday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

Phivolcs Director Renato Solidum told ANC no damage was reported from the earthquake since it happened offshore.

The earthquake, which was tectonic in origin, occurred 94 kilometers (kms) southwest of Palauig, Zambales at 8:26 a.m. It struck at a depth of 16 kms.

Intensity II was felt in Quezon City; Manila; Mandaluyong City; Ortigas, Pasig; Makati City; Obando, Bulacan; and Baguio City.

Solidum said the following aftershocks were recorded:

8:41 a.m. – magnitude 3.1 (94 kms northwest of Palauig)
9:07 a.m. – magnitude 2.9 (103 kms northwest of Palauig)
9:27 a.m. – magnitude 3.8 (90 kms northwest of Palauig)

More aftershocks are expected given the earthquake’s high magnitude, Solidum said.

A separate report from the US Geological Survey (USGS) also measured the magnitude of the earthquake at 6.0.

The agency said the earthquake took place 230 kms west northwest of Manila.
