The Silent Threat Beneath the Visayan Sea
The geological history of the Philippines is written in violent upheavals. Situated on the western rim of the Pacific Ring of Fire, the archipelago is a collision zone of tectonic plates, a land formed and frequently reformed by volcanic eruptions and seismic shifts. For centuries, the people of Cebu, the central province of the Visayas region, lived with a relative sense of seismic security compared to their neighbors. While the islands of Bohol, Leyte, Samar, and Mindanao frequently dominated the seismic records with catastrophic events, Northern Cebu was often viewed as a quieter zone, a place where the earth slept.
