The Department of Science and Technology – Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) will inaugurate its 100th Strong Motion station in Tanay, Rizal tomorrow, February 23.
DOST-PHIVOLCS in a statement today ( Monday) said the project is part of expanding its Philippine Strong Motion Network (PSMNet) and now in partnership with Tanay Municipal Government headed by Mayor Rex Manuel Tanjuatco.
The statement said PSMNet is one of the key earthquake monitoring networks in the Philippines that is equipped with strong-motion accelerographs strategically located in densely populated areas and near active faults.
It stated that these instruments are capable of faithfully recording large ground motion during high-magnitude earthquake events.
The DOST-PHIVOLCS said the data from the PSMNet can be used to provide critical information about the earthquake rupture process and understand the generation and propagation of seismic waves near the source.
The PSMNet will also characterize the type of materials underneath the soil, provide information about site effect and response; and determine the ground motion effects to buildings and ground failure such as landslides and liquefaction.
The agency said the information can be used by the PHIVOLCS Data Center for the development of an effective earthquake early warning system.
This will be also used by the academe and research institutions in studying the physics of strong earthquakes, urban planners for zonation, analysts for hazard assessment, and structural engineers in building earthquake resilient structures.
These will also be crucial in providing policy recommendations in order to mitigate the potential impacts of an earthquake.
The project started in 1992 with only four strong-motion instruments within Metro Manila.
With support from the national government and in collaboration with the Japanese government and academe such as Tokyo Institute of Technology (TITECH), the DOST-PHIVOLCS has continuously expanded the network within and outside Metro Manila, to eventually have adequate coverage of the entire Philippines.
