DOST-Philvocs Releases Earthquake Site Atlas For Davao





The local government here will now be guided in designing buildings and residential homes in areas vulnerable to earthquake, after the Department of Science and Technology-Philippine Institute of Volcanology and Seismology (DOST-Phivolcs) put out the Metro Davao Site Response Atlas.

The Metro Davao Site Response Atlas includes four maps that provide information to understand the ground motion and site response during strong earthquakes.

Dr. Renato Solidum Jr., Undersecretary for Disaster Risk Reduction and Climate Change and the officer-in-charge of Phivolcs, said the four maps are produced by earthquake experts and can be used to increase the seismic resiliency of residential and medium-to-high-rise buildings.

In an interview at the sidelines of the launch of the Metro Davao Earthquake Site Response here, Solidum explained how earthquake travels from the fault, the shaking of the ground and the concept period or the time it takes for the ground or the building to move back to its original position after the shaking.

Solidum said the maps can be used for the land use plan of local government units, as well for government infrastructure projects and the private-sector implemented construction works.

“So yung maps ang magbibigay ng (so the maps will provide) guidance for the specific design of the buildings,” he added.

Solidum said Davao City is eyeing to pass a resolution encouraging people to use the maps.

DOST-Phivolcs officials have briefed local disaster focal persons and representatives of national agencies about the maps during the Specific Earthquake Project Workshop, highlighting the importance of regulating building designs to prevent loss of lives and damage to properties.

The participants also identified ground conditions on site using the atlas, and estimate natural vibration of buildings to determine existing structures that are vulnerable to intense ground shaking.

According to Phivolcs, this critical information will guide earthquake risk reduction efforts, and comprehensive land use planning and development. (PNA)
