The province of Basilan has an aggregate historical jurisdiction of 135,892 hectares, with mainland Basilan encompassing an area of 124,892 hectares. The main island of Basilan is joined by the Pilas Group' of islands (now Hajji Muhtamad Municipality) west of the island, and the Bubuan and Tapiantana Group of islands (now Tabuan Lasa Municipality) in the south. These are listed among the Philippine islands with a moderate risk of getting hit by tsunamis. Geography
Basilan in Mindanao, Philippines (Regions IX, X, XII and ARMM) Basilan is geographically located between latitude 6°15' and 7°00' longitude 121°15' and 122°30'. Basilan is one of a system of 7,107 islands that make up the Philippine archipelago. Regionally, Basilan is the biggest and northernmost island of the Sulu Archipelago between the Philippine island of Mindanao and Borneo which includes about 400 islands. The island chain is one of two partial land bridges to Borneo and is an important migration route for birds. Basilan Strait, about 17 nautical miles (31 km) at its narrowest point, separates Basilan Island from the mainland of Mindanao and the port city of Zamboanga. The island is washed by the Basilan Strait from the North, the Sulu Sea from the Northwest and West, the Moro Gulf from the Northeast, and the Celebes Sea from the South, Southeast and East. Natural resources
The island of Omosmarata in Tuburan (now Mohammad Ajul) is listed among only fifteen (15) sites in the Philippines with commercially viable ocean thermal energy potential. The Philippines' ocean thermal resource area is 1000 square kilometers, based on the archipelagic nature of the country. Based on a study, the potential capacity for this resource is estimated to be 265 million megawatts. Likewise, the Basilan Strait is listed among only eight (8) sites in the Philippines with commercially viable ocean tidal energy potential (along with Bohol/Talibon Strait, Basiao Channel, Surigao Strait, Gaboc Channel, Hinatuan Passage, San Bernardino Strait and San Juanico Strait). Only the Provinces of Basilan, Samar and Surigao have both high ocean thermal and ocean tidal energy potential for future development, a veritable gold mine in energy if properly harnessed. Basilan likewise has fairly significant (yet underdeveloped) mineral deposits, specifically, iron ore ("basih"-lan), gold, manganese, copper, coal and rich agricultural lands. Alienable and disposable lands cover 862.249 km2, forest lands occupy 406.526 km2, 294.194 km2 are underused, 574.85 km2 are under forest cultivation, while 689.479 km2 are under agricultural cultivation. The Sulu Sea and Celebes Sea provides Basilan aquatic resources such as tuna, mackerel and sardines. Most of these are processed in canning factories located in nearby Zamboanga City, General Santos City (The Philippines' Tuna Capital), and Navotas. Climate
