The Philippine fault system is a major inter-related system of geological faults throughout the whole of the Philippine Archipelago, [1] primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt. [2] Some notable Philippine faults include the Guinayangan, Masbate and Leyte faults.
The subduction zones that surround most of the archipelago are the source of many of the larger earthquakes that strike the Philippines. This includes both faulting along the plate interfaces and within the subducting slabs. For the Philippine Trench, examples of those on the plate interface are the 1988 M w 7.3 and the 2023 M7.6 events.
There are 100 volcanoes in the Philippines listed by the Smithsonian Institution's Global Volcanism Program (GVP) at present, [6] of which 20 are categorized as "historical" and 59 as "Holocene". [6] The GVP lists volcanoes with historical, Holocene eruptions, or possibly older if strong signs of volcanism are still evident through thermal ...

Tectonic overview of the Philippines. Orange shading represents the Palawan Microcontinental Block; grey shading represents the Philippine Mobile Belt. The direction of triangles represents the direction of subduction. The subduction tectonics of the Philippines is the control of geology over the Philippine archipelago.
Taal Volcano (IPA:; Tagalog: Bulkang Taal) is a large caldera filled by Taal Lake in the Philippines. [1] Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake.

Importantly, the geological and geomorphological history of the slope including, for example, the prominent strike-slip movement of about 2.5 cm per year, has ultimately lead to failures all along the scarp, including the one that buried Guinsaugon.
