Metro Davao site response Atlas. Specific earthquake ground motion levels to help increase the seismic resiliency of residential and medium-to-high rise buildings in Metro Davao
The Metro Davao Site Response Atlas is a detailed compilation of specific earthquake ground motion level and site response hazard maps that would enhance seismic resiliency of residential and medium-to-high rise buildings located at Metro Davao.
This atlas includes:
- Active Faults Map of Davao Region from the Philippine Institute of Volcanology and Seismology,
- Geologic Map of Metro Davao from the Mines and Geosciences Bureau,
- Peak Ground Acceleration Map of Metro Davao,
- Vs30 Model Map of Metro Davao,
- Short Period Microzonation Map of Metro Davao,
- Long Period Microzonation Map of Metro Davao. These maps provide information to understand the ground motion characteristics of underlying rock and sediment deposits and ground motion response that may occur in Metro Davao in the event of an earthquake.
The Atlas is a compilation of maps showing seismic ground motion hazard assessment from various earthquake sources. Among the maps are Peak Ground Acceleration (PGA) and Spectral Acceleration (SA), which were modelled using Probabilistic Seismic Hazard Analysis (PSHA) through the collaborative efforts and expertise of engineers, seismologists, geologists and researchers from DOST – PHIVOLCS in consultation with various local stakeholders such as the Regional Development Council (RDC) XI, Association of Regional Executives of National Agencies (ARENA) XI, Department of Public Works and Highways (DPWH) XI, Philippine Institute of Civil Engineers (PICE) XI, Association of Structural Engineers of the Philippines - Regional Coordinating Council (ASEP-RCC), Association of Structural Engineers of Davao, Inc. (SEAD), the academe, the Provincial Government of Davao del Norte and Davao del Sur, the Local Government Units of Tagum City, Carmen, Panabo City, Island Garden City of Samal, Sta Cruz, Digos City and Davao City.
The MDEM Atlas can also be used as guide for earthquake impact assessment of national government agencies, Local Government Units (LGUs) in Metro Davao, engineering community, academe and the private sector.
