We applied these survey techniques to the area around Hsinchu, Taiwan, where is one of most important industrial area in Taiwan, to provide a basic information for earthquake disaster mitigation. For this, the gravity and microtoremor surveys have been carried out in the target area. Observations of gravity at 393 sites was done and the structure with some different scales are found from the Bouguer anomaly. The trend of the Bouguer anomaly is independent of the topography and some localized structures are observed. Furthermore, shallow structures were estimated from microtoremor data of array observation at some sites. As a result, the depth to bedrock is steeply variated from north-western to south-eastern area. The shape of the surface of bedrock represents the good agreement with the known geological information such as faults, anti- and syncline, and so on.
