Where is the Marikina fault line?

There are currently many talks about big earthquakes in the Philippines, especially after a 7.0 quake hit Haiti and killed hundreds of thousands of people.

A primary concern to most is the Philippine Fault Zone or the Marikina Valley Fault Line, which supposedly traverses through major parts of Metro Manila, including Marikina, Quezon City, Pasig and Taguig.

Where exactly does the Marikina Fault Line pass through?

The maps below from the Philippine Institute of Volcanology and Seismology (Phivolcs) and show us.

What is the Valley Fault System?

The Valley Fault System, also known as the Marikina Valley Fault System, is a group of dextral strike-slip fault which extends from San Mateo, Rizal to Taguig City on the south; running through the cities of Makati, Marikina, Paranaque, Pasig and Taguig. The fault possesses a threat of a large scale earthquake with a magnitude of 7 or higher within the Metro Manila area with death toll predicted to be as high as 35,000 and injuries of around 120,000, with more than three million people needed to be evacuated.

The fault contains two segments, known as West Valley Fault and East Valley Fault both located in the city of Marikina.

The west segment, known as the Western Marikina Fault was one of the two fault segments of the Valley Fault System which runs through the cities of Marikina, Pasig and Muntinlupa and moves in a dominantly dextral strike-slip motion. The West Fault is capable of producing large scale earthquakes on its active phases with a magnitude of 7 or higher.

The eastern segment, known as Eastern Marikina Fault moves in an oblique dextral motion.

    anyone who wants to know the names of subdivisions, barangays, and communities that are in the direct path of the marikina valley faultline; more than that, to zero in also on the NAMES OF STREETS and pinpoint exactly where the east and west valley faults run underneath the clueless residents of a heavily-populated metro and its suburbs, you can finally find the info here:

    as there is truth to the saying POWER IN INFORMATION, you can share this life-saving revelation by texting the internet address:

    …to your friends, loved ones, and acquaintances and challenging them to discover the truth themselves.

    it may be someday many people’s lives will be saved if we all just care and selflessly share what we strongly feel to be important and real.

    @ Media and Phivolcs kung puwede po sana maglagay kayo ng imahe dito ng faultline map na puwedeng imagnify ng mas malaki para makita ng detalyado ang mga lugar o streets na dinadaanan ng fault line, kase po masyadong maliit ang nailagay nyo dito, salamat po

    mga kababayan palaganapin po natin ang impormasyong nalalaman natin ngayun sa kahit anong pamamaraan. sa malaot madali maaaring mangyari ang pinangangambahan nating paggalaw ng fault line, iligtas po natin ang mga kababayan nating walang kaalam alam sa maaring mangyari. importante ang buhay. ang pagkain at kung anu ano pa. eh saka na natin problemahin. wag po nating panghinayangan ang maari nating maiiwanang materyal na bagay, buhay po muna natin ang ating unahin, hindi tayo pababayaan ng gobyerno at higit sa lahat eh ang ating Lumalang. mabuti na po yung lagi tayong handa. kung sa bagay po hindi namin masisi ang bawat isa kung mag aalala po tayo sa ating kahaharapin sa relocation sites. mas okey na po iyon kesa sa makita natin ang mahal sa buhay na namatay dahil sa katigasan ng ulo.
