Phivolcs Valley Fault System Atlas

**vinj** · June 5th, 2015 02:51 PM

Just to add, another main concern we see with the maps drawn up on the fault line is that it goes through Angat Dam, which supports maybe, what? 90% of our potable water requirements?

They made the Phivolcs atlas into separate pages. They should make it like Google maps where you can pan and zoom in and out. Come on guys, constant improvement.

Yung 5 meter recommendation is only to be safe from ground rupture hazard. There are other dangers such as ground shaking, liquefaction and landslides which can affect you even if you are not on top of the fault.

There is a popular mall in Muntinlupa which straddles the VFS. How they got the permit to build? One can also ask how they managed to cut down those pine trees up north without raising a fuss.

geo yatta, sino yan developer.

So tama pala ako based on my feelings. Kasi dati ko pa sinasbi yang katipunan going to libis hindi ko ramdam na quezon city.

Kung saan pa mamahalin mga lote yan pa yung mahlupet na dadaanan ng lindol. Pag sa west valley ba magbreak in half or magsink hole?

Pinky Webb: Para lang its clear the west valley fault runs through where to where

Mahar Lagmay: "it goes all the way from angat, then down to quezon city near lavista then down to pasig then greenmeadows area white plains and goes to taguig all the way to tagaytay.

Ok talaga sa lugar ko. No liquefaction at malayo sa west valley vault. The true quezon city is new manila erod, scout area, banawe, quezon avenue, tomas, timog, araneta ave, cubao, parts of aurora blvd, parts of commonwealth, yung sa circle na paikot na visayas, luzon, mindanao. Pero pag umabot na tandang sora hindi ko na mafeel qc.

Dapat talaga ihati na qc. Yung farview, novaliches dapat sa bulacan na ata ito eh. TApos yung libis katipunan ipasig marikina nyo na yan
