The Philippine Institute of Volcanology and Seismology (PHIVOLCS) Puerto Princesa Seismic Station said Monday that the Intensity 1 earthquake felt in the city and other parts of Palawan was “mild” and did not cause any harm.
Seismic station officer-in-charge Engr. Robert Esplida said Monday that the earthquake was recorded by their intensity meter at 5:07 a.m. The epicenter of the earthquake was located west of Lubang, Occidental Mindoro, with a magnitude of 6.4, and was felt not only in some barangays in Puerto Princesa, but also in Taytay, Roxas, Busuanga, El Nido, and Coron.
“Nag-register ng intensity one dito sa Puerto Princesa. Instrumento ‘yong naka-record noon at hindi naramdaman ng tao dito sa Puerto Princesa,” he said.
He mentioned that while the tremor was not experienced physically by locals in Puerto Princesa, it could be recorded through instruments due to its sensitivity to movements.
“Wala pa kaming ini-expect na damage sa earthquake na ito kasi doon sa malapit sa episentro nito sa Lubang ay may contacts kami don. So far wala pa naman recorded na damaged na properties. Ang aftershock lang nito ay tuloy-tuloy sa ganitong kalakas na lindol, basta more than 6.0, expected ang maraming aftershocks na mari-record,” he added.
“Yes, mild lamang ito. Wala naman dapat ipangamba ‘yong mga taga Palawan at Puerto Princesa, medyo malayo naman ang epicenter – nasa Mindoro ito. Iyon nga lang, naramdaman lang sa Palawan kasi medyo may kalakasan ‘yong earthquake,” he said.
The intensity meter of PHIVOLCS is continuously recording aftershocks from the earthquake at its epicenter in Lubang, he said.
Esplida further explained that the earthquake was of a tectonic type. It is produced by sudden movement along faults and plate boundaries.
“Ito ay tectonic in origin. May mga segment tayo, fault na gumalaw sa ilalim na ‘yon ang pinaka-source noong paggalaw ng lindol natin kaninang madaling-araw. Iyong plotting ng PhiVolcs ay tumatama sa Manila trench,” he said.
“Ang mga trenches na ‘yan, may active fault sa ilalim ng dagat. Ang epicenter ng earthquake kaninang 5:05 exactly ng umaga, tectonic in origin, pumapatak sa Manila trench ‘yong plotting ng epicenter, doon gumalaw,” he added.
