A moderately strong earthquake measuring 4.0-magnitude on the Richter scale has jolted parts of Batangas and Laguna afternoon of December 21, 2015, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.

The 4.0-magnitude earthquake was recorded at 12:42 p.m. and originated at 10 kilometers northeast of Tanauan City, Batangas.

It was felt at Intensity 4 or moderately strong in Tanauan City and Sto. Tomas in Batangas, and Los Baños in Laguna.

Phivolcs said an earthquake with this intensity is comparable to the "vibration of a passing heavy truck that is felt by people indoors and some people outdoors and may awaken light sleepers."

Intensity 3 was felt in Malvar, Batangas and San Pablo City in Laguna, which is relatively weak, "but some people may experience dizziness and nausea."

It was "slightly felt" at Intensity 2 in Lipa City and Talisay in Batangas; Calamba City in Laguna, and Muntinlupa City.

It was felt at Intensity 1 or scarcely perceptible in Batangas City and Tagaytay City.

The earthquake was tectonic in origin meaning the ground shaking was primarily due to the sudden movement in the earth's plates.

Phivolcs said there was no reported damage to property or loss of lives due to the earthquake. Likewise, aftershocks are not expected to occur.
