Jolo Group of Volcanoes

The Global Volcanism Program lists Jolo as one of the active volcanoes in the Philippines[1] while the Philippine Institute of Volcanology and Seismology (PHIVOLCS) collectively lists the group as Bud Dajo, one of the cinder cones on the island.

The highest point in the island is Mount Tumatangas[2] with an elevation of 811 metres (2,661 ft) asl.

On January 4, 1641, a volcanic eruption covered much of Mindanao in darkness and sent showers of ash as far as Cebu and Panay.

[3] From recent studies, the eruption was finally attributed to Mount Parker in South Cotabato.

Jolo Group is part of the Sulu Volcanic Arc, one of the two northeastern arms of the Sunda Plate which is in collision with the Philippine Mobile Belt.
