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 tectonics of the Philippines is the control of geology over the Philippine archipelago. The Philippine region is seismically active and has been progressively constructed by plates converging towards each other in multiple directions. [1] The region is also known as the Philippine Mobile Belt due to its complex tectonic setting.
Philippine Mobile Belt. In the geology of the Philippines, the Philippine Mobile Belt is a complex portion of the tectonic boundary between the Eurasian plate and the Philippine Sea plate, comprising most of the country of the Philippines. It includes two subduction zones, the Manila Trench to the west and the Philippine Trench to the east, as ...
The Marikina Valley fault system, also known as the Valley fault system (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. [2] It extends from Doña Remedios Trinidad, Bulacan in the north, running through the provinces of Rizal, the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna, before ending in ...
Sagami Trough. The Sagami Trough (相模トラフ, Sagami Torafu) also Sagami Trench, Sagami Megathrust, or Sagami Subduction Zone is a 340-kilometre (210 mi)long trough, which is the surface expression of the convergent plate boundary where the Philippine Sea plate is being subducted under the Okhotsk microplate. It stretches from the Boso ...
The Macolod Corridor is a northeast-trending zone of active volcanism situated at the junction of different tectonic elements in southwestern Luzon, Philippines. It is approximately 40 km wide and perpendicularly bisects the Luzon Volcanic Arc. The corridor is bounded by two major faults, the Philippine Fault to the west and the Sibuyan-Verde ...
The Sibuyan Sea Fault is located offshore north of Masbate. It is relayed with the Verde Passage Fault, both left-lateral faults, by an aborted spreading center. This fault is almost entirely offshore or is covered by Quaternary or Recent volcanic rocks. [1] It leaves the known Philippine fault northeast of Masbate Island, passes along the ...
The Philippine Sea plate or the Philippine plate is a tectonic plate comprising oceanic lithosphere that lies beneath the Philippine Sea, to the east of the Philippines. Most segments of the Philippines, including northern Luzon , are part of the Philippine Mobile Belt , which is geologically and tectonically separate from the Philippine Sea plate.
