A magnitude 2.5 earthquake struck off the town of Calatagan in Batangas province on Thursday afternoon, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.
According to Phivolcs, the epicenter of the minor tectonic earthquake, which occurred at 4:51 p.m., was located 21 kilometers southwest of the town. It had a depth of 98 kilometers.
A tectonic earthquake is caused by sudden movements along faults and plate boundaries.
Phivolcs said the tremor is not expected to cause any damage or aftershocks. Another magnitude 2.5 tectonic tremor also hit Calatagan on Oct. 6.
Calatagan is located 71 kilometers from Batangas City and 131 kilometers from Metro Manila.

Batangas is among the most seismically active areas in the Philippines, primarily due to the Lubang Fault situated between Mindoro Island and Batangas.
The Philippines sits along the Pacific ‘Ring of Fire,’ where tectonic plates collide, causing frequent seismic and volcanic activity. /mr
