研究期間：10108~10207;In order to serve different earthquake studies, a seismologic instrument service center has been set up by Taiwan Earthquake Research Center. The center manages different kinds of earthquake instruments to support different high-density, short-term, and long-term observations of earthquakes and imaging details of earth structures. The seismologic instrument service center has been very successful in the past years. Due to different research methods and purposes, Taiwan Earthquake Research Center further organizes the “geophysical instrument service center” to manage the instruments other than seismology’s. The geophysical instruments include: seismic reflection/refraction, gravity and magnetic, geo-electric, geothermal, marine geophysics and well logging. The geophysical instrument center will provide experts for testing, installation, archive data and other services. In this year, the major efforts will focus on: (1) set up a ground penetrating radar (GPR) system to investigate detailed near surface geologic structures; (2) increase 3 OBS instruments, except resupplying the OBS lost last year in the Taiwan-Strait, also to prepare for more ocean seismic studies; (3) build a vibroseis source for reflection seismics, to promote the high-resolution seismic structure study; (4) increase 72-channel reflection seismic system to join the operation with the new vibroseis source; (5) develops and implements a training course for users to enhance the operation of seismology instrumentation; and (6) provides technical support and manpower for major reseach projects.
