| Description: | In mid-1992, the Institute of Earth Sciences (IES), Academia Sinica, along with several domestic and foreign institutions, began to prepare a prospectus for establishing a broadband seismic network in the Taiwan region. The network, later named Broadband Array in Taiwan for Seismology (BATS), is designed with 15 permanent stations located in Taiwan region, covering an area of approximately 350 km by 400 km. There are additional 15 portable units that can be deployed for intensive observations as needed. The network entered test operation in late 1994 and has produced high-quality data in sufficient quantity since early 1996 (Kao et al., 1998a; Kao and Jian, 1999). The BATS instrumentation is designed to cover a variety of research demands. All permanent stations are equipped with state-of-the-art very-broadband (Streckeisen STS-1 or STS-2) and strong-motion (Terra Technology SSA-320) sensors and 24-bits digital recorders (Quanterra Q-680 or Q-4120). Data streams with high sampling rates (>=80 samples per s) are recorded in triggering mode, while others are recorded in continuous mode on both hard disks and magnetic tapes. All stations are capable of telecommunication for immediate retrieval of specific events. Preliminary data quality control is performed at IES. Afterwards, the data are contributed to the Data Management Center of the Incorporated Research Institutions for Seismology (DMC, IRIS) for distribution. One of BATS' original goals is to routinely estimate source parameters of earthquakes occurring in the region, particular those offshore events east of the island where coverage by the local network is poor. The stability and tectonic implications of our work have been demonstrated in a previous study (Kao et al., 1998a). The solutions are routinely posted in this web site and sent out through e-mail.
