dc.description.abstract | Studies have indicated that the power of seismic waves, rather than the acceleration and velocity, strongly correlates with the level of structural damage and the shutdown of high-tech equipment during high-precision process. However, current earthquake early warning (EEW) systems in Taiwan issue a warning only for a seismic wave with high acceleration or velocity but not for that with high power. To extend the application of the EEW system to high-tech fields, conventional and novel hybrid prediction models were developed in this study to predict the ground motion power and to issue EEWs for high-power ground motions. A conventional prediction model that relies on earthquake source parameters was first developed to determine ground motion characteristics, and a hybrid prediction model that relies not only on earthquake source parameters but also on the on-site ground motion parameter of P-waves was developed to improve the prediction accuracy. The two-step maximum likelihood method was used to derive model coefficients for considering the mixed effect of the ground motion records. The source, path, and site effects on the short-period power and the long-period power of ground motions were illustrated by the proposed models. A method for determining a broadcast scenario of EEW systems for high-power ground motions with a target success rate and damage threshold was also developed. These novel prediction models can be used to develop a customized EEW system to provide an early warning for high-power seismic waves in Taiwan. | en_US |
