MANILA (2nd UPDATE)—A 5.5-magnitude earthquake jolted Quezon province early Thursday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said, but there were no immediate reports of damage.
The tectonic tremor occurred at 4:52 a.m. at a depth of 7 kilometers northeast of Jomalig town.
It was felt in parts of Metro Manila, Camarines Norte, Pampanga, and nearby provinces, according to Phivolcs.
Intensity 4, which may feel like a passing of heavy truck and cause hanging objects to swing considerably, was reported in Guinayangan, Quezon.
Marikina City, Navotas City and Quezon City experienced intensity 2 or "slight felt" shaking while Muntinlupa City had intensity 1 or "scarcely perceptible" shaking.
Instrumental intensities or the strength of tremors measured by the intensity meter were recorded in the following areas:
- Intensity 4 - Guinayangan, Quezon; Jose Panganiban, Camarines Norte
- Intensity 3 - Pili, Camarines Sur; Mauban, Lopez and Mulanay, Quezon
- Intensity 2 - Marikina City; Malolos City; Gumaca and Dolores, Quezon; Baler, Aurora
- Intensity 1 - Iriga City; Malabon City; San Juan City; Quezon City; Pasig City; Guagua, Pampanga; Talisay, Batangas; Palayan City
Phivolcs said the quake would spawn aftershocks.
'NO TRIGGERING EFFECT'
Phivolcs director Renato Solidum said the shallow earthquake could cause minor infrastructure damage if its epicenter is located on land.
He also quelled fears the tremor may generate a tsunami.
"Hindi sapat ang enerhiya o magnitude ng lindol na mag-trigger ng paggalaw ng tubig," Solidum told "Umagang Kay Ganda."
(The earthquake's magnitude is not enough to trigger waves.)
The state seismology chief also denied that the latest quake is connected to the string of tremors in Mindanao last month.
"Wala po silang kaugnayan. Nagkataon lang na nagkakaroon ng mga paglindol sa iba't ibang dako sa Pilipinas. Hindi magkadugtong itong mga faults na gumalaw so wala po silang triggering effect," Solidum said.
(They are not related. It just so happened there are quakes hitting parts of the Philippines. The faults are not interconnected so there's no triggering effect.)
