It is proposed that the Philippine Trench and PFZ represent a 'shear partitioning' mechanism, where the oblique physical motions of subduction at the convergent zone resulted in the development of the major strike-slip fault. In the Philippine Sea, the oblique motion of the subducting Philippine Sea plate resulted in the formation of the ...
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 North Bohol Fault or Inabanga fault is a reverse fault located at Anonang, Inabanga which was found on 15 October 2013 during the Bohol earthquake. According to the Philippine Institute of Volcanology and Seismology, a new fault occurs only once in a century. The North Bohol fault, shaped as a hanging wall and also known as the "Great Wall ...
The Philippine archipelago is also cut along its length by a left-lateral strike-slip fault known as the Philippine Fault. [5] [1] Active subduction disturbs the Earth's crust, leading to volcanic activity, earthquakes, and tsunamis, making the Philippines one of the most geologically hazard-prone regions on Earth. [4] [6]
The Macolod Corridor is an important geological feature for several reasons. First, it is a zone of active volcanism, which poses a significant hazard to the surrounding population. Second, the corridor is located at the junction of several tectonic elements, which makes it an ideal place to study the tectonic processes that affect the Philippines.
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 Sibuyan Sea Fault is located ...
The Philippine trench is hypothesized to be younger than 8–9 million years old. The central part of the Philippine fault formed during the Plio-Pleistocene times [15] is considered to be an active depression of the Earth's crust. [16] The trench formed from a collision between the Palawan and Zamboanga plates.
The Manila Trench near western Luzon and Mindoro, the Philippine Trench in the east, and the Philippine Mobile Belt. The Manila Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Luzon and Mindoro in the Philippines.
