Magnitude 5.3 Earthquake Hits Waters Off Cagayan Province
A magnitude 5.3 earthquake struck the waters off Cagayan province on the morning of Saturday, July 19, 2025, sources said. The event rattled communities northeast of Dalupiri Island in Calayan town.
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported the tremor occurred around 9:34 a.m., about 13 kilometers northeast of Dalupiri Island. Aftershocks are expected to follow, local leaders noted.
Details on the Earthquake’s Impact
Phivolcs recorded an Instrumental Intensity I (Scarcely Perceptible) level in nearby Claveria town. The quake originated at a depth of 10 kilometers and was tectonic, caused by movements in the Earth’s crust.
This preliminary data came from Phivolcs’ automatic monitoring system, which quickly detects seismic activities across the region.
Concurrent Weather Conditions
This seismic event coincided with Tropical Storm Crising, internationally known as Wipha, moving across extreme Northern Luzon. The storm was last tracked approximately 125 kilometers west-northwest of Calayan town, adding to the region’s challenges.
While the earthquake caused minor tremors in surrounding areas, no immediate damage or casualties were reported. Authorities continue to monitor both the storm and seismic activity to ensure public safety.
