TAIGER 五項工作 1. 天然地震:陸地寬頻網 Land broadband instruments to enhance the existing broadband networks for recording both local earthquakes and teleseisms (Ongoing) 2. 天然地震:海底寬頻網 Marine broadband deployment around the island to increase the aperture of the available broadband networks (2007/10) 3. 人工震源:Land explosions for low-fold wide angle and CMP profile reflections across the island along three transects (2008/02)
How TAIGER (Ct’d) 4. 海陸聯炸:Marine MCS and reversed sea-land wide-angle profiling using airgun signals along six transects (2008/4) 5. 大地電磁:Magnetotellurics along several transects (Ongoing )
