A magnitude 6.3 earthquake rocked Batangas province around 10:19 a.m. on Thursday, June 15, said the Philippine Institute of Volcanology and Seismology (Phivolcs).

Phivolcs traced the epicenter of the 6.3-magnitude quake at 15 kilometers southwest of Calatagan, Batangas. 

It was initially measured as a 6.2-magnitude earthquake


Phivolcs said the tremor was felt at Intensity IV (moderately strong) in Manila City; Mandaluyong City; Quezon City; Valenzuela City; Malolos City in Bulacan; Batangas City, Ibaan, Lemery, Nasugbu, and Talisay in Batangas; Dasmariñas City and Tagaytay City in Cavite; and Tanay in Rizal.

Meanwhile, it was felt at Intensity III (weak) in Pateros, Metro Manila; Las Piñas City; Makati City; Marikina City; Parañaque City; Pasig City; Obando in Bulacan; Laurel in Batangas; Bacoor City and Imus City in Cavite; San Pablo and San Pedro in Laguna; and San Mateo in Rizal.

Phivolcs’ instruments also recorded the quake at Intensity IV Abucay, Bataan, San Ildefonso in Bulacan, Magallanes in Cavite, San Jose in Occidental Mindoro, Calapan City and Puerto Galera in Oriental Mindoro, and San Antonio, Olongapo City, and Cabangan in Zambales.

Phivolcs pointed out the quake was due to the movement in the Manila Trench—a major earthquake generator located offshore west of Luzon island, which is roughly parallel to the Philippine archipelago and is running from Taiwan to Occidental Mindoro.

It said the earthquake may have caused damage to houses, buildings, and other infrastructure, and warned the public to be cautious as aftershocks may occur.

However, no tsunami warning has been issued by Phivolcs.
