Magnitude 6.1 earthquakes struck northeast of Bagamanoc, Catanduanes early Wednesday morning, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). The tremor, which occurred at 5:19 a.m., was tectonic in origin with a depth of 38 kilometers.
The earthquake was felt in various parts of the Bicol region, with residents of Irosin, Sorsogon reporting a mild tremor at Intensity I. Although the quake’s magnitude was significant, PHIVOLCS stated that no major damage was expected from the incident. However, they cautioned the public to remain vigilant as aftershocks may still occur in the coming hours or days.
Earthquake Details
The tectonic nature of the earthquake indicates that it was caused by the movement of the Earth’s crust, rather than volcanic activity. The epicenter was located northeast of Bagamanoc, a town in Catanduanes, an island province in the Bicol region. Catanduanes, known for their vulnerability to natural disasters such as typhoons, rarely experience earthquakes of this magnitude, making today’s event notable.
Residents in Irosin, Sorsogon reported feeling mild shaking. Intensity I quakes are typically imperceptible except under favorable conditions, meaning that the quake was barely felt, with little to no disruption. Despite its low impact, PHIVOLCS advised residents to stay alert as aftershocks could still happen, though they are not expected to be destructive.
Preparedness Reminders
Although no major damage was expected, authorities continue to remind the public to review safety protocols in the event of future quakes or aftershocks. PHIVOLCS encouraged the public to secure heavy objects in homes and workplaces, check the stability of structures, and familiarize themselves with evacuation plans.
Local disaster risk reduction units have been placed on standby, ready to respond if any aftershocks cause issues in the region. So far, there have been no reports of injuries or disruptions to infrastructure.
Continued Monitoring
PHIVOLCS continues to monitor the situation closely, providing updates as necessary. The agency has a network of seismic monitoring stations throughout the country, allowing them to track quakes and provide timely warnings to affected areas.
This earthquake serves as a reminder of the Philippines’ position along the Pacific Ring of Fire, where tectonic activity is common, making earthquake preparedness vital for all Filipinos.
