Interactive Map for the West and East Valley Fault Line on Rizal, Metro Manila, Laguna, Cavite

The West and East Valley Fault System span from Angat, Bulacan all the way down to Carmona, Cavite and Calamba, Laguna and is the most feared event that could hit Metro Manila in case the fault system moves as it may cause larger than 7.0 magnitude earthquake. As of the meantime, disaster resiliency assessors have been saying that the country is not prepared for a calamity such as this. Schadow1 Expeditions has acquired the fault line data from PHIVOLCS and traced it on top of OpenStreetMap and Google Earth.

We have recently acquired the fault line data for the West and East Valley Fault System from PHIVOLCS and have decided to trace the data on top of OpenStreetMap Philippines and on Google Earth. This is to provide a graphical representation of the exact infrastructures that lies on top of the fault line so that everyone will be aware of the dangers and prepare for the future.

The last known activity along this fault line was the year 1658 and is estimated to be active every 300 years plus or minus 100 years. As of the time of this writing, it has been 356 years ago and is well within the potential period of its movement.

The photo above is a snapshot along the area of Muntinlupa and San Pedro, Laguna where the red line is a part of the West Valley Fault Line.

We have prepared a trace of the fault line over Google Earth and can be downloaded here (Mirror1|Mirror2). (05/19/2015 - Added additional fault line estimates traces as plotted from June 2014 PHIVOLCS VFS-GMMA Atlas)

The fault line starts at Montalban Landfill of Montalban Rizal and ends at San Lazaro Leisure Park and Casino at Carmona, Cavite. Although, recent studies of PHIVOLCS shows it still extends from Carmona to Silang and to Calamba, Laguna. We are still waiting for the precise data so we can add the fault line's extension at the interactive map. As of October 2, 2014, we have acquired the additional data and extended the fault line until Calamba, Laguna.

These are the following notable barangays, villages, and infrastructure that lie exactly on top or within a 500-meter radius from the fault line.

  1. May tinatayo nang high near Ever Commonwealth so immediate danger from the line sa Batasan Hills tama ba? Two projects underway in fact. Di ako sure sa target number of floors nila pero nakakalagpas na sampu. Wala bang building code violations dito?

    1. Sir sa park spring san pedro laguna po mern b faultline

    2. May fault line b sa park spring san pedro laguna

  2. Specifically where in batasan hills?

  3. What about filinvest calamba laguna project? Almost 4 or 5 barangay's ang nasakop nila i think.maraming villages sa loob ng calamba de ciudad.

    1. Have not included it on the list as its nearest feature to the West Valley Fault is about 5.48 kilometers away.

  4. Hi! I'd like to ask if you can confirm the accuracy of the interactive map? Though very helpful I find that it may be a little inaccurate? Basing on the google earth map provided with the overlay of the fault line map, it is a bit off to the right? Kindly confirm as it is sensitive information. Thank you! :)

    1. It is only as accurate as how PHIVOLCS plotted it on its overlay map. Possibly 5-10 meters accuracy as per optical recognition through trace.

  5. what about AVIDA Village in Canlubang how far is it from the faultline

  6. Hello there, I would like to know when did you update this article since it's said that you have acquired the add'l data last october 2, but the date's states that you have published this last july 11 2014. I would like to confirm since I'm going to use this as a reference for out term paper. Thanks

  7. Bagong silang north caloocan maaapektuhan din po ba or mkksama din dyan sa west valley fault line?

    1. Na-check mo na ba yung downloadable interactive map? Sa nakikita ko, 10.4km away ang bagong silang sa pinakamalapit na fault line. Maapektuhan? Kapag magkalindol, maaari. Pero direktang maaapektuhan, hindi.

  8. Saan ang saktong lugar sa carmona estates tatama??

  9. Im from carmona estates.. thats so scary.

  10. Your downloadable interactive map cant be open, it says:
    Error (429)
    This account's public links are generating too much traffic and have been temporarily disabled!

    1. Apologies as the server housing the interactive map was down due to excessive traffic. I have added mirrors so it can be downloaded elsewhere.

  11. Increase awareness is what we can do to save lives and minimize damage as we cannot stop mother nature. Updating the information here especially on areas that will be affected will help. I'm sharing this.

  12. How about certain subdivisions in Antipolo like Havila, Maia Alta and iba pang magkakalapit na subdivisions dito? Tatamaan po ba ng fault line?

    1. I think its too far n! Ateneo, barangka and sta. Elena ang nearest place s binanggit mo so napakalayo n s antipolo.

    2. What about po cainta rizal .ala pong direct place basta rizal lng. .apektado po ba. Tnx po sa reply

  13. Kahit anong preparedeness ang gawin natin kalikasan po ito wala tayo magagawa dito panalangin lamang po ang makakapagligtas at pananamplataya sa panginoon Hesu Kristo tayo mag balik loob s panginoon upanv sa gayon ay tayoy kanya kaawaan....AMEN lets start praying

    1. You cant just pray you idiot, and you have no right to tell people to just sit and do nothing but pray. Its better to be prepared.

    2. Walang magagawa dasal mo kung hindi ka rin handa. Ugok puro dasal nalang inaatupag ng pinoy kaya hindi umaasenso ayaw naman mag trabaho

    3. Wag mo namang sabihang ugok, still may maligro sa pagdarasal,kahit prepared ka kung hindi ka naman sumasampalataya wala rin!! Kung mabibigyan mo trabaho ang mga tulad nating mga Pinoy, siguro hindi mo masasabi na puro dasal na lang ang ginagawa nating mga pinoy kaya di umaasenso. Talagang
      kulang lang tayo sa mga job opportunities dito sa Pinas, kaya nga mga nag aabroad ang karamihan sa ating mga kababayan eh!

    4. kung puro dasal at walang gawa patay...mismo anh bibliya ang nag sabi nito...magdasal at mag wag.nag away...

  14. HI, listed among your list is Rizal, are we talking about the whole town here being on top of the fault line? Can you provide specific bgys or villages just like the others? Thanks!

    1. I believe the Rizal in the list is Barangay Rizal in Makati just south of Barangay Aguho in Pateros as there are more specific areas in the province of Rizal listed before it.

  15. Prayers always, nothing is impossible with God.

  16. Malapit ba sa colina homes nang camellia sa San Pedro Laguna ang mga fault line nang San Pedro? Kakabili Lang namen na bahay don..

  17. The blog mentioned that Alabang Hills Village lies in the fault line. This is incorrect -- the village close to the fault line is actually Alabang 400. Please refer to PHILVOLCS instead of this blog:

How devastating (for lack of a better/nicer word) will be it for us who live there? Thanks. God bless all of us.

  44. One can just use Google Earth to measure distances from the fault line to the location of choice, given that the fault line layer is uploaded. The assumption is if the epicenter is shallow enough, if you are nearer the fault line, the more damage you experience, but many things can still happen.

  45. If we look closely on the details of the Atlas it covers most of Mega Manila including down Laguna and Cavite areas. No wonder why there are so many "rent-to-own" "for as low as" promotions around. Land owners know these facts so they must dispose their lands as fast and profitable as possible. Let us not forget that the most devastating natural calamity is an earthquake, with regards to the most number of lives lost. There are no such thing as "100% earthquake proof" building or construction, although it may help to retrofit. This is a sad reality that people are into profit than safety. In my opinion and as i have compared other maps from Phivolcs and Safest areas would be New Manila, San Juan, Camanava-Obando, Meycuayan, Marilao. The dilemma is when we go east it's landslide and faultlines. If we go west it floods. Opinions differ, I opt to expeience flooding ( we can raise our houses and float in flood) than experience an earthquake and watch everything fall down apart. Hard earned money and lives at stake. Flood subsides, earthquake stops. Praying for the safety of everyone, Let's make better choices.

  46. Kasama po b ang bulacan ano2 pong part?

  47. Then, may ipapalabas pa na movie, yun San Andreas. Mas lalong mag cause ng pagpanic yan sa mga filipino, magiging blockbuster yang movie dahil maraming manonood dahil sensational na naman ang topic na earthquake ngayon.

  48. Rizal province po specially angono nearby laguna lake ano po effect.may tendency po ba na tumaas ang level nang tubig before and after the big 1, ..pls, inform us, thanxs

  49. salamat naman at hindi kasama ang mandaluyong sa vally fault!!! sa mga tatamaan sana po this time mag umpisa na po kayong mag handa at MAGDASAL nasa hindi ganon kalakas ang maging hagupit ng kalikasan...

  50. we never expected this fault line to extend this far. is there a safe distance from the fault line that we can consider safe? if ever my house lies along the fault line will my house be damaged? I never thought the fault line will reach even cavite area and maybe up to laguna. be safe everyone!

    1. According to PHIVOLCS, the safe distance from a faultline so a structure will not be "eaten" by the soil through liquefaction during an earthquake triggered by the same fault line is 5 meters. However the real issue during an earthquake is seismic waves that travels radially across the epicenter. For that information, you may view the separate article for the risk map here

  51. God Bless to all of us.. He knows everything :)

  52. What would be the possible movement of the fault? Side ways or up/down

  53. What type of quake motion are you concluding? Up/down or side ways. We are almost to conclude a lot purchase in Vista Real Classica 2. Will this area be in the 500 radius?

  54. Maapektuhan po ba buong pilipinas?maapektuan po ba yubg ibang lugar ??
