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 Metro Manila Subway, [7] formerly known as the Mega Manila Subway (MMS) is an under-construction underground rapid transit line in Metro Manila, Philippines.The 33-kilometer (21 mi) line, which will run north–south between Valenzuela, Quezon City, Pasig, Taguig, Parañaque and Pasay, consists of 17 stations between the East Valenzuela and Bicutan stations.
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.
The strips generally run north–south and the zones of convergence are usually demarcated by fault lines. The Philippine Mobile Belt is compressed on the west by the Eurasian plate and two arms of the Sunda plate , and on the east by the Philippine Sea plate .
In Metro Manila the estimated hazard has a mean PGA of 0.32 g for a PoE of 10% in 50 years. The main hazard comes from shallow fault sources, such as the Marikina Valley Fault System, but there is an important contribution to the overall hazard from the Manila subduction zone to the west and the potential for strong shaking from earthquakes ...
It results from the subduction of the Eurasian plate beneath the Philippine Mobile Belt along the Manila Trench since the early Miocene. [22] Volcanoes are younger in the south than in the north near Taiwan. Subduction started in Taiwan around 16 Ma, but there are younger volcanoes in Mindanao which are dated only to the Quaternary.

Off the west coast of Luzon, the Manila Trench accommodates eastward subduction. To its east is the East Luzon Trench, a convergent boundary that separates the Philippine Trench by a transform fault. The left-lateral strike-slip Philippine fault system runs through the islands. It is one of the longest strike-slip faults in the world.
In 2014, under the Roadmap for Transport Infrastructure Development for Metro Manila and Its Surrounding Areas (Region III & Region IV-A; also known as the Metro Manila Dream Plan), the JICA study proposes a 46.7-kilometer (29.0 mi) expressway from the Manila–Cavite Expressway to San Jose Del Monte in Bulacan to pass above the existing C-5.
