1. Introduction
On February 8, 1990, the Bohol Sea, nestled between the islands of Mindanao, Bohol, and Negros, became the epicenter of a sudden and destructive undersea earthquake. The shock produced a tsunami that surged onto nearby coastal communities, causing loss of life and property in the central Philippines.
2. Seismic Activity in the Bohol Region
✔️ The earthquake registered magnitude 6.8, strong enough to trigger wave generation.
