The central Philippine Fault Zone consisting of the Guinayangan, Masbate, and Central Leyte faults are the most seismically active regions transecting the islands of Bondoc to Leyte. The northern and southern extensions of the Philippine Fault Zone experience infrequent earthquakes and often described as locked segments which are capable of ...

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 ...
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. [2]
The Bohol fault system is a reverse fault system in Bohol province, Philippines. This fault system contains three segments: the newly found North Bohol Fault following the 2013 Bohol earthquake, [2] the South Offshore Fault, [3] and the East Bohol Fault. The North Bohol Fault is located in Inabanga and near Clarin.
The Sibuyan Sea Fault is a part of the Philippine Fault System, a major inter-related system of geological faults throughout the whole of the Philippine Archipelago. This fault system is primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt .
The PTZ also displays blind thrust faults and folds (essentially buried folds and faults). It has been suggested that these thrust faults originated along preexisting normal faults. These blind thrust faults present potential danger as they are likely candidates for the causes of high-magnitude earthquakes, and in effect large-scale tsunamis. [18]
Major physiographic elements of the Philippine Mobile Belt Puerto Princesa Subterranean River National Park marker describing the geologic history of the Philippines. 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.
