There are five active fault lines in the country namely the Western Philippine Fault, the Eastern Philippine Fault, the South of Mindanao Fault, Central Philippine Fault and the Marikina/Valley Fault System.

What is the biggest fault line in the Philippines?

The 1,200-km-long Philippine fault zone (PFZ) is a major tectonic feature that transects the whole Philippine archipelago from northwestern Luzon to southeastern Mindanao.

Where are the major faults in the Philippines?

The central Philippine Fault Zone consisting of the Guinayangan, Masbate, and Central Leyte faults are the most seismically active regions transecting the islands of Bondoc to Leyte.

What are 5 active faults in Central Visayas?

There are many active faults in the archipelago, but the closest active faults in the Bohol region are the Cebu lineaments, central Negros Fault, Panay Fault and the western Mindanao Fault.

What type of fault is the eastern Philippine Fault?

The Philippine fault is a major left-lateral strike-slip fault that runs through the Philippine archipelago (Fig. 1).

What is the longest fault line?

The Ring of Fire is the largest and most active fault line in the world, stretching from New Zealand, all around the east coast of Asia, over to Canada and the USA and all the way down to the southern tip of South America and causes more than 90 percent of the world’s earthquakes.

How many active faults are there in the Philippines?

There are about 30 active fault systems in the Philippines from where earthquakes may originate. Two of the most common faults are the Philippine Fault consisting of at least 20 segments distributed from Luzon to Mindanao and the Valley Fault System consisting of two segments transecting the GMMA area.

Where is Marikina fault line located?

Where is the Marikina Valley Fault? The Valley Fault System extends from Doña Remedios Trinidad, Bulacan in the north. It 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.

Where is the fault line in Manila?

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.

What type of fault is Southern Mindanao fault?

This 1250-km-long left-lateral strike-slip fault traverses the entire Philippine archipelago from northwestern Luzon Island in the north to eastern Mindanao in the south.

Is Lubang fault active?

Batangas is one of the seismically active areas in the Philippines. Another offshore earthquake generator is Lubang Fault, located between Mindoro Island and Batangas, which is also the locus of small to large-magnitude earthquakes.

Where is western Philippine Fault?

The West Valley Fault is 100 kilometers in length and traverses the cities of Metro Manila namely Taguig, Muntinlupa, Paranaque, Quezon City, Pasig, Makati, and Marikina as well as nearby provinces of Rizal, Laguna, Cavite, and Bulacan. These places will suffer greatly when this fault move.

What kind of faults are found in Central Philippine Fault Zone?

The central Philippine Fault Zone (PFZ) is comprised of the Guinyangan fault, Masbate fault, and CLF. This part of the PFZ is found to be the locus of great earthquakes, fault creep activity and most probably a slow-slip event.

What are the 3 major earthquake zones?

The Earth has three major earthquake zones. The first large area known as the Pacific Ring of Fire. The second major earthquake zone is along the mid-ocean ridges. The third major earthquake zone is the Eurasian-Melanesian mountain belt.

What are the 5 major fault lines in the world?

They are :
Juan De Fuca Plate.Pacific Plate.Nazca Plate.Scotia Plate.Cocos Plate.Caribbean Plate.Philippine Plate.Fiji Plate.

Where are the most active fault lines?

The San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and passes through much of the state. It will create the biggest earthquakes—as big as magnitude 8—that will disrupt the whole region.
