The West Valley Fault System stands as one of the significant geological features in the Philippines, with its presence looming over the landscape of Taguig City.

Spanning through various barangays, this fault system carries implications for residents and urban planners alike, necessitating a deeper understanding of its ramifications. This guide provides insights into the impact of "The Big One" on areas within Taguig City when it becomes active and how to prepare for it.

What is the West Valley Fault System?

The West Valley Fault System, also known as the Marikina Valley Fault System, is a major geological fault traversing through the Greater Metro Manila area. It is part of the larger Philippine Fault System, which extends across the archipelago.

This fault system is predominantly a strike-slip fault, where tectonic plates move horizontally past each other, posing significant seismic hazards to populated areas.

Affected Areas in Taguig City

In Taguig City, several barangays fall within the vicinity of the West Valley Fault System. These include:

  • Bagumbayan
  • Central Bicutan
  • Comembo
  • East Rembo
  • Lower Bicutan
  • Maharlika Village
  • North Signal Village
  • Pembo
  • Pinagsama
  • Rizal
  • South Daang Hari
  • South Signal Village
  • Tanyag
  • Upper Bicutan
  • Ususan

It's essential for residents of these areas to be aware of the fault system's presence and the potential risks associated with it.

Utilizing PHIVOLCS FaultFinder

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) provides a valuable tool called FaultFinder, which enables individuals to trace fault lines not only in Metro Manila but throughout the entire country. This tool empowers citizens and authorities to identify areas prone to seismic activity, facilitating informed decision-making in urban planning, disaster preparedness, and risk mitigation efforts.

By using the PHIVOLCS FaultFinder, residents and authorities can access crucial information about fault lines, aiding in the development of strategies to minimize the impact of potential earthquakes.

Through awareness, education, and the utilization of tools like PHIVOLCS FaultFinder, communities can better prepare and mitigate the risks associated with seismic hazards, ensuring the safety and resilience of residents in earthquake-prone areas.
