PHIVOLCS' Marikina Fault Line Map for Taguig City and Makati City

 Previously, I posted about the portion of Marikina Fault Line that passes through Alabang, Muntinlupa. That post contained a map from the Philippine Institute for Volcanology and Seismology (PHIVOLCS) and a short list of places that were traversed by the fault line.

Now, let us see another area in Metro Manila that is affected by the Marikina Fault Line. This area is the city of Taguig and the southern portions of Makati City.

According to this PHIVOLCS fault line map, the Marikina Fault Line passes through the following areas in Taguig City:

1. Barangay North Signal Village
2. Area between Maria Reyna ng Apostoles Church and Heritage Park
3. Barangay Pinagkaisa
    - Sto. Niño Village
    - Wildcat Village
    - Palar Village

The Marikina Fault Line crossed the boundary of Taguig and continued to Makati City in these areas:

1. Barangay Rizal
3. Barangay Pembo
    - Area just east of Pembo Elementary School

The red lines on the PHIVOLCS fault line map above indicate the location of the Marikina Fault Line. To better understand the meaning of the red lines, please read this legend:

The map I posted here can be viewed and downloaded from the PHIVOLCS website. In addition to the PHIVOLCS fault line map, I also used Google Maps and Wikimapia data for this post.

It is scary to know that your house or workplace sits on or near the Marikina Fault Line. The fear is compounded by the fact that PHIVOLCS said that the Marikina Fault Line is ripe for movement. This means that a big earthquake will happen any time.

I hope that the city governments of Taguig and Makati take a serious preparations for the big earthquake. Residents, for their part, should also do some preparations like strengthening their homes or moving to another place that are far away from the Marikina Fault Line.

Do you wish to know if your house stands on or near the Marikina Fault Line? I suggest that you read the following posts:

Index Maps of Marikina Fault Line
Areas Affected by the Big Earthquake of the Marikina Fault Line

You should also read PHIVOLCS’ tips on how to be prepared for earthquakes.

I also recommend Nababaha.com’s map of Marikina Fault Line because it overlaid the fault line on Google Maps.

New Index of Marikina Fault Line Map

I noticed that there is a new update to the website of the Philippine Institute of Volcanology and Seismology (PHIVOLCS). This update brought both good news and bad news not only to me but to everyone who wanted to get plenty of information about the West Valley Fault, or more popularly known as the Marikina Fault Line.

The good news is that they replaced the old index for Marikina Fault Line maps (which you can check on this blog post) with a better looking one:

Index of Marikina Fault Line map (Source: PHIVOLCS website)

The new index map is colorful and gives a clearer overview of the areas affected by the Marikina Fault Line.

The new index map shows that the Marikina Fault Line passes through the Bulacan towns of Doña Remedios Trinidad, Norzagaray, and San Jose Del Monte City; Rizal town of Rodriguez (Montalban);  Metro Manila cities of Quezon, Marikina, Pasig, Makati, Taguig, and Muntinlupa; Laguna towns of San Pedro,  Biñan, Santa Rosa City, Cabuyao, and Calamba City; and the Cavite towns of General Mariano Alvarez, Carmona, and Silang.

The bad news is that the large scale Marikina Fault Line maps are gone. They can not be viewed on the PHIVOLCS website. I am not sure if the link to the maps was just broken or the PHIVOLCS people removed the maps intentionally.

We do not know if PHIVOLCS will return the maps or not.

It is good that PHIVOLCS improved the map index but that improvement is useless if the more important large scale Marikina Fault Line maps are hidden from the public view.

If PHIVOLCS really want people to be informed about earthquakes and the hazards that they brings then should upload the large scale Marikina Fault Line maps back to their website.
