Background and Purpose

Bangkok Metropolitan Area is the center of economic and social of Thailand with population more than 10 million people. Many buildings and infrastructures have been built. Even though Bangkok is located at a remote distance from seismic sources, a recent seismic studies show that Bangkok is at risk by distant and long-period earthquake ground motion. This project is consist of three main purposes; 1) to grasp the shaking characteristics of the Bangkok deep sediment, 2) to construct the 3D model of the Bangkok basin, and 3) to develop a prototype of the long-period earthquake early warning system.

Project Achievements

The project was done by the cooperative research with Mahidol University, Chiang Mai University and Thai Meteorological Department. Shaking characteristics of the Bangkok deep basin was investigated. The 3D model of the Bangkok basin was constructed. Finally a prototype of prediction equations for long-period earthquake ground motion was proposed. These equations could be used as an early warning system for long-period ground motion if the magnitude and the location is obtained just after the earthquake.

Future Prospects

Researches and the relation among co-researchers in Mahidol University, Chiang Mai University and Thai Meteorological Department will be continued and promoted based on the two-year collaborative works. We are going to submit journal papers and extend the collaborative research to aim the implementation of the long-period earthquake early warning system developed in this study.
