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
βοΈ The earthquake registered magnitude 6.8, strong enough to trigger wave generation.
βοΈ The region is located within the Philippine Mobile Belt, a tectonically active area.
βοΈ The epicenter was located offshore near Camiguin Island.
3. The Tsunami Strikes
πΉ Waves reportedly reached heights of 2β3 meters in some coastal areas.
πΉ The tsunami hit with little warning, catching communities off guard.
