The Department of Science and Technology – Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) will launch and turnover the Spectral Acceleration Maps of the Philippines (SAM PH) Atlas to the Department of Public Works and Highways (DPWH) and to the Association of Structural Engineers of the Philippines (ASEP) through the InfoSentro sa PHIVOLCS on 23 March 2021 9:00 AM via Zoom.

The SAM PH Atlas supports the Build! Build! Build! Program of the Government as this can serve as a reference for engineers, building designers, and urban planners in the design of essential and critical structures and facilities such as hospitals, dams, power plants, roads, bridges, and railway systems to withstand intensity VIII earthquakes.

It can also be used for the assessment and retrofitting of existing structures to conform to the building standards. Along with the Model Atlases for the Philippines, Metro Manila, Metro Cebu, and Metro Davao published from 2018 to 2019, the SAM PH Atlas can provide science-based information for urban development, risk assessment, and site-specific insurance rates and coverages.

“We firmly hope that this latest atlas will be utilized by all stakeholders for decision-making in building safer structures and facilities, and for strengthening the resiliency of our communities,” said DOST Undersecretary and PHIVOLCS Officer-in-Charge Renato U. Solidum, Jr.

Aside from the national and regional scale spectral acceleration maps, the Atlas contains maps of historical earthquakes from 1619 to 2015, and active faults and trenches in the country.

These spectral acceleration maps may be adopted in the 8th Edition of the National Structural Code of the Philippines (NSCP) planned for release in 2022. A digital copy of the atlas will be made downloadable for free on the DOSTPHIVOLCS website (
