Numerous pyroclastic cones and craters dot 60-km-wide Jolo Island at the SW end of the Philippines archipelago. Jolo lies in the Sulu archipelago, about 150 km SW of the tip of the Zamboanga Peninsula on SW Mindanao Island. The isolated location of Jolo and political unrest have inhibited geological studies of the volcanic island. Youthful-looking Tumatangus volcano forms the 811 m high point of the island. Bud Dajo (or Buddajo) is a young basaltic cinder cone that reaches 620 m elevation; nearby cones are Matanding, Guimba, and Sungal. Hot springs have been reported at craters on Cagayan Sulu, and solfataras at Siit Lake. A tsunami accompanied a possible submarine eruption in 1897. A reported eruption in 1641 actually reflected ashfall from the eruption of Parker volcano on Mindanao.

The dumbbell-shaped, E-W-trending Jolo island contains numerous pyroclastic cones and craters, some of which are visible in this Space Shuttle image with north to the upper left. The island is about 60 km wide in an E-W direction; its largest city, Jolo, lies on the northern coast (left-center). The isolated location of Jolo at the SW end of the Philippines archipelago as well as political unrest have inhibited geological studies of the volcano.

Forested Bud Dajo cinder cone is one of numerous pyroclastic cones and craters that dot 60-km-wide Jolo Island at the SW end of the Philippines archipelago. Bud Dajo (or Buddajo) is a young basaltic cinder cone that reaches 620 m elevation; nearby cones are Matanding, Guimba, and Sungal. Hot springs have been reported at craters on Cagayan Sulu, and solfataras at Siit Lake. A tsunami accompanied a possible submarine eruption in 1897.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
