The Department of Science and Technology – Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) will conduct a training and presentation workshop entitled, “Long-Period Ground Motion and Seismic Safety of High-rise Buildings in the Philippines.” It is scheduled to take place tomorrow, April 18, 2024 from 8:00 AM to 5:00 PM at the PHIVOLCS Auditorium, C. P. Garcia Avenue, Diliman, Quezon City. Expected participants are engineers, property managers, and local government units.

The workshop will feature a distinguished line-up of speakers from Tokyo Institute of Technology and other experts in the field to primarily discuss the long-period ground motion and high-rise building response in Japan and in the Philippines. The workshop will also serve as the launching of results for the DOST-GIA-funded project “Prediction of Long-Period Ground Motion in Megacities of the Philippines Critical to the Seismic Safety of High-Rise Buildings.”

The long-period ground motion can significantly affect high-rise structures during earthquakes. A first in the Philippines, the project attempts to predict longperiod ground motion from any seismic source. The ground motion prediction provides three-component synthetic simulations that can be compared to actual acceleration records of significant earthquakes. The consistency of the data will be used to predict ground motions and generate simulation maps, which can be used to evaluate the site response and building performance during strong earthquakes. This is necessary to accurately estimate the site response and risk of high-rise buildings, especially in megacities such as Metro Manila and Metro Cebu, to earthquake damages.
