No Damage, But 19 Aftershocks: Quezon Quake Shakes Up Afternoon, Not Tied To West Valley Fault

A surprise jolt shook parts of Quezon and nearby provinces just past noon today, when a magnitude 4.6 earthquake hit at 12:17 PM. While it definitely startled residents, the good news? No damage has been reported so far—and nope, it’s not connected to the infamous West Valley Fault.
According to PHIVOLCS, the quake actually started out as a magnitude 5.1 event but was later downgraded to 4.6. It struck at a shallow depth of 11 kilometers and was traced to a local fault in the Sierra Madre mountain range.
Since the main quake, 19 aftershocks have followed—nine of which were officially plotted. Only one of those was strong enough to be felt by the public, and the rest ranged between magnitudes 1.4 and 3.6. So far, nothing alarming.
Precautionary measures quickly kicked in. Our Lady of Fatima University (OLFU) suspended classes in Valenzuela and Quezon City, and Calamba City announced a work suspension for safety. Meanwhile, dam operators in Central Luzon kept a close eye on Angat, Ipo, Bustos, and Pantabangan Dams, but reported everything’s still stable. Over in Caliraya, no impact was seen on the dam there either.
Even public transportation in Metro Manila took a short pause before resuming operations. Some schools, like PUP Sta. Mesa and other OLFU branches, briefly closed their doors before reopening once things settled.
At the national level, the NDRRMC held virtual huddles with their regional teams in NCR, Calabarzon, Central Luzon, and Mimaropa to coordinate any needed responses. So far, local disaster councils in Aurora, Quezon, and surrounding areas have seen no major concerns but continue to do rounds for any signs of damage.
OCD Calabarzon, in particular, is on alert and actively posting updates and safety reminders across social media. They’re reminding everyone to review earthquake safety tips, especially the trusty “Duck, Cover, and Hold” routine.
Defense Secretary Gilberto Teodoro Jr., who also heads the NDRRMC, reminded all agencies to be ready for anything. He stressed the importance of clear communication between national and regional teams within 30 minutes of a quake—and made sure that alarm systems and backup protocols are being checked and enforced.
Bottom line: the situation is under control, and no injuries or damages have been reported. Still, authorities are urging the public to stay calm, alert, and keep tuned in to official updates—just in case.
Because when it comes to earthquakes in the Philippines, it’s always better to be prepared than surprised.
