OCCIDENTAL MINDORO / RankWire.AI / – A Magnitude 5.4 earthquake shook near Occidental Mindoro in the Philippines on Friday morning. The tremors extended across parts of Luzon and Metro Manila. The Philippine Institute of Volcanology and Seismology, or PHIVOLCS, recorded the event at 10:38 a.m. local time. Its epicenter was approximately 13 kilometers southwest of Mamburao, the provincial capital. The quake had a depth of roughly 14 kilometers and resulted from tectonic activity.
Initially, officials listed the quake as magnitude 5.8. However, further analysis lowered the reading to 5.4. PHIVOLCS warned that aftershocks might follow the main tremor. Based on the initial assessment, they did not expect significant damage. Many residents across Mindoro felt noticeable shaking during late morning, with weaker tremors reaching neighboring provinces. The earthquake also impacted parts of the capital region, more than 100 kilometers from the closest point to the epicenter.
Mamburao experienced Intensity 5 shaking, along with several communities in Oriental Mindoro. Calapan City, Naujan, Puerto Galera, San Teodoro, and Victoria all reported the same intensity. Taal in Batangas and towns in Occidental Mindoro such as Abra de Ilog and Sablayan experienced Intensity 4. Instruments registered Intensity 5 in Mamburao and Puerto Galera. Most of the strongest readings were concentrated across Mindoro, where the community ground movement was most pronounced.
Shaking reaches into Metro Manila
The tremor was felt in Metro Manila and farther north in several provinces. Instruments recorded Intensity 3 in Quezon City, Batangas City, Calapan City, and Victoria. General Trias in Cavite and San Pedro in Laguna also experienced Intensity 3. Some residents in Manila moved outdoors as a precaution during the shaking. After the tremor ended, normal activities resumed. Authorities continued inspecting affected areas for damages.
Communities around Luzon registered lower seismic readings. Parañaque City experienced Intensity 2, along with Santa Cruz in Laguna and Guinayangan in Quezon. Seismic measurements varied by location, reflecting differing ground motions. Officials reported no major structural damage during the initial evaluation. Monitoring persisted after the main earthquake. Local authorities and seismic stations watched for additional tremors near Occidental Mindoro.
Official magnitude update confirms 5.4 reading
The revised measurement confirmed the earthquake at magnitude 5.4 after experts reviewed the initial seismic data. The depth remained around 14 kilometers. The epicenter was southwest of Mamburao. Communities in Occidental and Oriental Mindoro experienced the strongest shaking. Weaker tremors extended to Batangas, Cavite, Laguna, Quezon, and Metro Manila. The distribution of intensity readings showed residents across much of Luzon felt the quake on Friday morning.
The Philippines is prone to frequent earthquakes. Several active tectonic boundaries surround and cross the archipelago. National monitoring stations track seismic activity and update measurements as new data arrives. Friday’s quake, centered near Occidental Mindoro, caused widespread shaking. Initial assessments found no significant damage. Authorities continued to monitor for aftershocks following the event. The official magnitude remains 5.4, replacing the preliminary, stronger reading issued right after the quake.
