The 1645 Luzon earthquake was one of the most destructive earthquakes to hit the Philippines. It occurred on November 30 at about 08:00 PM local time on Luzon Island in the northern part of the country. The island was struck by a 7.5 M s tremor produced by the San Manuel and Gabaldon Faults (Nueva Ecija) in the central section of the island. [1]
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 ...
Strike-slip deformation within the Philippine Mobile Belt occurs as a result of oblique subduction of the Philippine Sea plate, where the Philippine Fault System accommodates much of it. [5] The fault is seismically active and ruptures periodically in large earthquakes. Among the largest are the 1990 Luzon and 1973 Ragay Gulf earthquakes.
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.
Along this trench the oceanic crust of the Sunda Plate beneath the Celebes Sea is being subducted beneath the Philippines Mobile Belt. It forms part of a linked set of trenches along the western side of the Philippines formed over east-dipping subduction zones, including the Manila Trench and the Negros Trench . [ 1 ]
