  3. Taiwan’s Seismicity: One-hundred Years 台灣百年地震分布

  4. Historical Tsunamis

  5. Institute of Earth Sciences Academia Sinica 中央研究院 地球科學研究所 Director Associate Director (1) Administrative Office Advisory Committee (11) 諮詢委員會 (3 years) Geophysics/ Seismology 地球物理/地震 (17) Geochemistry/Geology 地球化學 / 地質學 (11) Engineer/ Technician (8) General Facility/Support 設施支援 (5)

  6. Brief History • 1971: Taskforce of Taiwan’s earthquake research, under the National Science Council • 1973: The Earthquake Division in the Institute of Physics, Academia Sinica • 1982: Institute of Earth Sciences, Academia Sinica • 2005: Taiwan Earthquake Center (TEC), Data Center

  7. Geophysical Field Network / Instruments • Seismic • broad-band, strong motion, OBS, geophone, rotational, downhole, SAFE-Taipei, Vietnam etc., temporary arrays (TAIGER, Tatun, 101-Building…) • GPS (“PBO in Taiwan”) • Strainmeter(Longitudinal Valley) • Tiltmeter(池上Fault, Longitudinal Valley) • Gravity • superconducting, absolute, relative, continuous vs. campaign • Infrasound • Heat flow • Groundwater level • Magnetics

  8. 台灣的地震儀網（中央氣象局 CWB 為主）： （左）短週期儀網；（中）強震儀網；（右）寬頻儀網。 S13/SP TSMIP BATS

  9. 地球所地震觀測網之分佈 Seismic Arrays in the Taipei Metropolitan Area (2002~) Strong Motion Network in the Mountain Area (2005~) Southern Taiwan Transect Seismic Array (2005~)

  10. Broadband Seismic Array in Taipei Basin BB free-field BB downhole 大屯 火山 林口 台地

  11. Strong-Motion Downhole Array in Taipei Basin : closed (4) : operation (8) 大屯 火山 林口 台地

  12. The Taipei 101 Tower seismic array

  13. Strong Motion Network in the Mountain Area (MTN)

  14. Southern Taiwan Transect Seismic Array(2005) NW STTA (25 Stations, 140 km) SE

  15. Recent International cooperation 喬治亞共合國 Tarim 菲律賓 台灣 西藏 所羅門群島 越南

  16. 寬頻地震網小型衛星遙測系統(VSAT) (Very Small Aperture Terminal，VSAT) VSAT小型衛星遙測系統: 小型天線終端地面電臺，同步軌道衛星，中型天線 地面中心站 VSAT可用以傳遞聲音、影像與數據資料。適合地域廣大的偏遠地區、高 山、離島的國家，以解決傳統地震站佈線與資料收集的不便性。 馬 尼 拉 海 溝 中心站 (地球所與中央大學) 衛星 安達曼群島 菲律賓火山暨 地震學研究所 野外站 中新一號衛星 Aligia2衛星

  17. Continuous GPS Arrays in Taiwan > 300 stations Installed and operated by CWB / IES / MOI
