The Philippine propagates northwards in the segment of East Luzon Trench. [14] [24] [23] The age of the Philippine Trench is not well-defined; estimates range from 5 Ma or younger, [28] [1] to 8–9 Ma. [29] [22] However, researchers agree that the Philippine Trench is the youngest trench in the Philippine subduction system. [19] [30] [6] [1]

The Mindoro block is a microcontinental block located in the Philippine Mobile Belt and the east side of North Palawan Block.It has comprises a metamorphic basement (Mindoro Metamorphics of Teves, 1953) of unknown but probably pre-late cretaceous age, overlain locally by upper cretaceous basalts (Karig, 1983), and more regionally succeeded by a probable upper eocene sequence of basinal clastic ...
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.
The National Committee on Geological Sciences was created via Executive order no. 625 on October 8, 1980. This committee is under the Office of the President of the Philippines, which consists of 21 government agencies headed by the Mines and Geosciences Bureau (MGB) of the Department of Environment and Natural Resources (DENR).

A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
Philippines map of Köppen climate classification zones. The Philippines has a tropical maritime climate that is usually hot and humid. There are three seasons: tag-init or tag-araw, the hot dry season or summer from March to May; tag-ulan, the rainy season from June to November; and tag-lamig, the cool dry season from December to February.
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. This caused a change in geological processes creating a subduction zone, that is dropping the ocean floor deeper. [15]
