Taiwan Rapid Earthquake Information Release System

Abstract

INTRODUCTION Interest in rapid access to earthquake information has grown enormously in the past few years (Gee et al. , 1996; Teng et al. , 1997; Wu et al. , 1997). In addition to satisfying the public and media needs, rapid notification programs provide valuable information for rapid earthquake disaster response, thereby mitigating the loss. Recognizing the importance of rapid earthquake information for seismic hazard mitigation, efforts to design and implement systems to provide rapid earthquake information have expanded over the last 10 years (Heaton, 1985; Nakamura and Tucker, 1988; Buland and Person, 1992; Romanowicz et al. , 1993; Bakun et al. , 1994; Espinosa Aranda et al. , 1995; Lee et al. , 1996; Shin et al. , 1996; Teng et al. , 1997; Wu et al. , 1997). In 1989, a telemetered, digital, short-period seismograph network of 75 three-component field stations was installed in Taiwan (see Figure 1) using Teledyne Geotech 1-Hz short-period sensors (Teledyne S13). The signals...
