Manila, Philippines: To avert threat to life and property in case of a strong earthquake, the Quezon City government in Philippines is considering the declaration of some areas along the West Valley Fault as non-residential zones, according to City Mayor Herbert Bautista.
The city government has identified 594 lots in 24 subdivisions located within the five-meter buffer zone of the West Valley Fault System, formerly known as the Marikina Valley Fault, and included them in the city’s electronic geographical mapping project.
“Concerned government agencies should have full coordination in efforts to lessen the impact of a possible movement of the fault once an earthquake hits the country,” Bautista said. The areas within the buffer zone could be declared as open parks or educational areas where science-related professionals could master their specializations, the mayor added.
The proposal came after Subdivision Administration Unit chief architect Pedro Rodriguez Jr. reported that the Information Technology Development Office had included the Valley Fault System into the proposed e-Geographical Information System. Rodriguez said the Philippine Institute of Volcanology and Seismology (Phivolcs) had informed the property owners of the 594 lots about the Valley Fault System and the buffer zone.
Bautista said the proposed educational zone would allow urban planners, geodetic engineers and other science-related professionals or students to study or master their own specialisations. Meanwhile, Rodriguez suggested that the buffer zone be included in the city’s Comprehensive Land Use Plan and that the Phivolcs issue a corresponding clearance prior to the city government’s issuance of a locational clearance to areas on or near the Valley Fault System. He also recommended the installation of physical markers at the actual locations of the fault line in coordination with the Phivolcs.
