Taiwan Earthquake Research Center Geophysical Instrument Service Program2020

In order to serve variable 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 mainly 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 effort will focus on: (1) Construct a three-component cable-free seismic system, and enhance the detection capability of seismic surveys in terrain relief areas or dense forest areas. Also cooperate with temporary seismic observation networks to collect seismic record; (2) increase one resistivity image profiling (RIP) system to investigate detailed near-surface geologic structures or for real-time landslide monitoring; (3) increase magnetic surveying instruments, increase the density of magnetic observation stations, and study with earthquake precursors; (4) increase 2 OBS instruments to prepare for more seismic sea-land studies, especially in Taiwan Strait; (5) develops and implements training courses for users to promote the operation of geophysical instruments; and (6) provides technical support and manpower for major research projects.
