Earthquakes. Earthquakes occur due to the collision, separation or sliding motion of plate boundaries. The point of collision is called the focus point.

Strong Motion Network in Taiwan Strong Motion Forum COSMOS Sep. 25, 2012, 5:15-7:15pm Room 1.08, Lisbon Congress Center Strong Motion Network in Taiwan Kuo-Liang, Wen Dept. of Earth Sciences National Central Univ., Taiwan

Taiwan Strong Motion Instrumentation Program (TSMIP) Started from 1990 Installed and maintained by CWB (http://www.cwb.gov.tw ) Strong Motion Station More than 809 110 real-time stations 57 building arrays 16-bit and 24-bit

CWB High-quality Downhole Earthquake Monitoring Network Down to the depth of 300 m or bedrock Surface and downhole strong motion seismograph, and downhole broadband seismograph Improve the quality of seismograms and the accuracy of earthquake locations

Geophysical Database Management System (GDMS) http://gdms.cwb.gov.tw GDMS provides CWB various seismic observation data available for principal research fellows of seismic study But, the register of GDMS is only for Taiwan user now Anonymous users can download the data of real-time stations only for recent felt earthquakes and the disastrous earthquakes webqry@cwb.gov.tw

Engineering Geological Database for TSMIP (EGDT, http://egdt. ncree This project was established by CWB and NCREE since 2000 to collect and provide the subsurface data of TSMIP stations Site investigations at 447 station sites were completed with depth of at least 35 m

The general information (the photo of the seismograph, the plan section and the cross section of the surrounding environment), the soil profile, the SPT-N value, the shear wave velocity, and the primary wave velocity of the stratum are all available on EGDT website All the data is open to refer, and the complete digital data can be provided by submitting a requirement Based on the database, the VS30, site classification, and other site-related researches have been done (Kuo et al., 2011 and 2012)
