The Zambales Ophiolite Complex (also called Zambales Ophiolite) is a large, well-preserved exposure of oceanic crust located in the western portion of Luzon Island, Philippines. [1] It is considered one of the best-preserved and most studied ophiolites , offering valuable insights into the formation and evolution of oceanic crust and the ...
The Philippine archipelago is bounded by subduction zones which makes the region volcanically active. The most active volcano in the Philippines is the Mayon Volcano located in southeastern Luzon. [36] It is related to the subduction of Philippine Sea plate beneath the Philippine Mobile Belt. [4] Earthquakes (mag >6.0) in the Philippines (2019)

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 ]
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.
It trends northerly as it separates Buruanga peninsula from the Antique Range in Panay Island, and passes offshore northwards east of Tablas Island. The present geodynamic setting of the Philippines obliges the Tablas Lineament to operate as a right-lateral strike-slip fault. Its structure appears to connect with the Negros Trench southwards.
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.
Ilocos-Central Luzon Basin is a sedimentary basin and stratigraphic formation in the Ilocos Region and Central Luzon Region, Philippines. [1] It is one of the 16 major sedimentary basins in the country and stretches from the vicinity of the Manila metropolitan area in the south to Ilocos Norte in the north.
