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.
The Cotabato Trench is an oceanic trench in the Pacific Ocean, off the southwestern coast of Mindanao in the Philippines. 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 ...
The Manila Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Luzon and Mindoro in the Philippines. The trench reaches a depth of about 5,400 metres (17,700 ft), [8] in contrast with the average depth of the South China Sea of about 1,500 metres (4,900 ft). It is created by subduction, in which the Sunda Plate ...
Philippine Mobile Belt. 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 includes two subduction zones, the Manila Trench to the west and the Philippine Trench to the east, as ...
The Philippine Trench (also called the Philippine Deep, Mindanao Trench, and the Mindanao Deep) is a submarine trench to the east of the Philippines. The trench is located in the Philippine sea of the western North Pacific Ocean and continues NNW-SSE. [1] It has a length of approximately 1,320 kilometres (820 miles) and a width of about 30 km ...
Philippine Fault System. The Philippine Fault System is a major inter-related system of geological faults throughout the whole of the Philippine Archipelago, [1] primarily caused by tectonic forces compressing the Philippines into what geophysicists call the Philippine Mobile Belt. [2] Some notable Philippine faults include the Guinayangan ...
Largest. Mw 8.3 1918 Celebes Sea earthquake. Deadliest. M w 8.0 1976 Moro Gulf earthquake 5,000–8,000 killed. The Philippines lies within the zone of complex interaction between several tectonic plates, involving multiple subduction zones and one large zone of strike-slip, all of which are associated with major earthquakes.
In plate tectonics, the Nankai Trough marks a subduction zone that is caused by subduction of the Philippine Sea Plate beneath Japan, part of the Eurasian Plate (Kanda et al., 2004). This plate boundary would be an oceanic trench except for a high flux of sediments that fills the trench.
