Phivolcs sees geohazard, flooding risks in Bulacan Airport

The project site of the proposed New Manila International Airport in Bulacan has geohazard risks, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

The multi-billion airport is sitting on soft ground and its location is prone to frequent flooding, according to Phivolcs Usec. Renato Solidum.

“Just to be very specific on the facts is that it is far away from the fault. But since it’s underlain by sand with a shallow water table, it’s prone to strong ground shaking and liquefaction,” he said.

Solidum said they conducted an assessment to ensure the safety of the community as well as to protect investments. He recommended making buildings and infrastructure resilient to hazards.

“Dapat iyong building mo ay maayos ang disenyo na maging stable siya habang lumilindol at hindi siya tumagilid. Or pwede mo ring patibayan ang lupa. Bawasan mo iyong tubig, palitan mo iyong lupa, (The building should have a proper design for it to be stable during earthquakes. The ground can also be strengthen by reducing its water content or replacing the soil),” he added.

Meanwhile, San Miguel Holdings Corporation (SMC) said they have been taking into account the risks in designing the P740 billion domestic and international airport in Bulacan. The SMC also assured they have studied the project, including its feasibility, and all possible risks.

“The airport’s design fully takes this into account and we have actually started implementing sustainable measures to address flooding in Bulacan that has existed for several decades and has been made worse by clogged waterways and drainages,” according to SMC.

The corporation also tapped three major global airport construction firms to ensure the airport is resilient, sustainable, and will provide the best benefits for all Filipinos. AAC (with reports from Vincent Arboleda)
