Based on the available geologic and geomorphologic data, 708 Taiwan Strong-Motion Instrumentation Program (TSMIP) free-field strong-motion station sites are classified using a scheme compatible with the 1997 Uniform Building Code (UBC) provisions. Results show that an extensive usage of geologic maps and geomorphologic data for site classification is satisfactory and is a quick and effective method for categorizing large numbers of strong-motion station sites. The response spectral shapes (RSS) method and the horizontal-to-vertical spectral ratio (HVSR) method both provide good supplements for checking purposes. Field checks are definitely necessary, especially for sites located near geologic boundaries or geomorphologic boundaries. Final...
