context_page_description: The Marikina Valley Fault System, also known as the Valley Fault System, is a dominantly dextral strike-slip fault system in Luzon, Philippines. It extends from Doña Remedios Trinidad, Bulacan in the north and runs through the provinces of Rizal, and the Metro Manila cities of Quezon, Marikina, Pasig, Makati, Taguig and Muntinlupa, and the provinces of Cavite and Laguna that ends in Canlubang.
context_section_description: The fault contains two major segments, known as West Valley Fault (WVF) and East Valley Fault (EVF).
  West Valley Fault
  The west segment, known as the West Valley Fault (WVF) is one of the two major fault segments of the Valley Fault System which runs through Metro Manila to the cities of Marikina, Quezon City, Pasig, Makati, Taguig and Muntinlupa and moves in a dominantly dextral strike-slip motion. The West Valley Fault segment traverses from Doña Remedios Trinidad to Calamba with a length of 129.47 kilometres (80.45 mi).
  The West Fault is capable of producing large scale earthquakes on its active phases with a magnitude of 7 or higher.
  East Valley Fault
  The eastern segment, known as East Valley Fault (EVF) moves in an oblique dextral motion. It extends to about 17.24 kilometres (10.71 mi) from Rodriguez to San Mateo in the province of Rizal.
