Q1. Why is the station located inside the Shibajianshan tunnel in Hsinchu?
A： A precedent is the European Center for Geodynamics and Seismology in Luxembourg, expanded inside an abandoned mine (http://www.ecgs.lu/). The Bo-ai main tunnel of Shibajianshan in Hsinchu offers structural integrity, a low water table, low vibration and easy access. After favourable site evaluations by gravity experts from Germany and Japan, MOI obtained the use of the tunnel from the Ministry of National Defense, signed a contract with ITRI in August 2004 and accepted the completed station in December 2006.
