About Bohol

Bohol is about 700 kilometers directly south of Manila and is about 70 kilometers southeast of Mactan Island. The province must have been developed from the magmatic tectonic mechanism which resulted from the underthrusting of the southwest Philippine plate east of Samar and Surigao. The Alicia Schist, the oldest known rock formation in the island, is inferred to be a part of the Bohol crystal rocks before plate interactions. All the succeeding igneous extrusive and intrusive rocks to accumulate were marine and terrestrial deposits in the Bohol basin. As of the year 2000, Bohol had a population of about 1.137 million growing at an average annual rate of 2.79%. Tagbilaran City is the most densely populated area at more than 2 thousand persons per square kilometer of land.
