The Department of Science and Technology - Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) will be conducting the “Virtual Launch and Turnover Ceremony of the Specific Earthquake Project Site Response Atlases” on October 22, 2021 via Zoom.

Atlases for six (6) sites, namely (1) Pangasinan, (2) Tarlac, (3) Metro Iloilo-Guimaras, (4) Cauayan City, (5) Butuan City, and (6) Mati City, were developed under the project “Specific Earthquake Ground Motion Levels to Help Increase the Seismic Resiliency of Government Infrastructures, Residential, and Medium-to-High Rise Buildings in Pangasinan, Tarlac, Metro Iloilo-Guimaras, Cauayan City, Butuan City, and Mati City” funded by DOST-Philippine Council for Industry, Energy, and Emerging Technology Research and Development (PCIEERD).  These atlases are compilations of maps depicting site response and resulting earthquake ground motion that would help increase the seismic resiliency of infrastructures in the study areas by providing ground motion data for seismic load design considerations. These include Peak Ground Acceleration Maps, Vs30 Model Maps, Short-Period Microzonation Maps, and Long-Period Microzonation Maps. These maps provide information to collectively understand the dynamic characteristics of the underlying soil and rock layers affecting the ground motion in the event of an earthquake.

The online event will have lectures to guide users on how to interpret and apply the data presented in the maps, and panel discussions to highlight the importance of regulating building designs based on the observed ground motion for earthquake risk reduction. The participants are from the Local Government Units of the project sites, particularly from the Engineering Offices, Planning and Development Offices, and Disaster Risk Reduction and Management Offices, who are target end-users of the atlas for urban planning and building design regulation. Representatives from the Department of Public Works and Highways (DPWH), Association of Structural Engineers of the Philippines (ASEP), Philippine Institute of Civil Engineers (PICE), Mines and Geoscience Bureau (MGB), academe, private sectors, and media partners are invited to this event.

Digital copies of the Site Response Atlases may be downloaded from the DOST-PHIVOLCS website: after the turnover.
