A magnitude 5.8 earthquake struck the Ilocos Norte region in northern Luzon, Philippines, on Tuesday, July 15, 2025, according to the German Research Centre for Geosciences (GFZ).
The tremor was recorded at a depth of 10 kilometers (6.2 miles), which qualifies as shallow and increases the likelihood of being felt strongly at the surface.
Other monitoring agencies, such as Turkey’s Anadolu Agency, cited a slightly deeper depth of 27 kilometers.
The epicenter was located 29 kilometers northwest of Pasuquin, a coastal municipality in Ilocos Norte. The quake was widely felt across multiple provinces in northern Luzon, including Ilocos Sur, Cagayan, Isabela, and Abra.
Residents reported brief but sharp shaking, with some temporarily evacuating buildings and offices as a precaution.
Despite the quake’s intensity, no major damage or injuries have been reported as of this writing.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) confirmed the event and noted that while aftershocks are expected, they are unlikely to be destructive.
Local disaster response units have been mobilized to assess the situation and ensure community safety.
The Philippines is part of the Pacific Ring of Fire, a seismically active region where earthquakes and volcanic eruptions occur frequently due to the movement of tectonic plates. Luzon, in particular, experiences periodic seismic activity, making preparedness a key priority for residents and local authorities.
Authorities have advised the public to remain alert, avoid spreading unverified information, and follow updates from official agencies such as PHIVOLCS and local disaster councils.
