On May 18, 2015, PHIVOLCS (Philippine Institute for Volcanology and Seismology) has released an atlas showing the stretch of the West Valley Fault and East Valley fault line in Greater Manila Area .
The Valley Fault System Atlas was distributed to local government agencies and it is also available online. This is to help the local government to warn their constituents of the impending danger and train them for disaster preparedness in case a strong magnitude-7 earthquake would strike.
The Valley Fault System is divided into two namely: West Valley Fault and East Valley Fault. Both fault lines span from Rizal near Bulacan all the way down to Carmona, Cavite.
The East Valley Fault line is only 10 km in length and crosses along the municipalities of Rodriguez and San Mateo, Rizal.
Areas that stand close to the fault (represented in red line) in Rodriguez are Macabud, San Isidro, San Jose, San Rafael (Rosario) and Burgos.
In San Mateo: Guinayang, Malanday, Maly, Dulong Bayan 2, Sta. Ana, Ampid, Guitnang Bayan 1 and 2. The East Valley Fault Line ends in Maly-Maalang Road near Ichin Cooperative.
To be continued.
