No latest activity reported for Jolo.

Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

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.
