Imaging the Geological Structures of Taiwan with the High-Density Magnetotelluric Surveys

In the study we plan to build the marine-Land magnetotelluric (MT) synchronized movable Arrays, as the USArray project in the United States and SinoProbe project in mainland China, for synchronized MT surveys in selected areas in both the Taiwan Strait and the western foothill of Taiwan within four years. Within limited budget scale, we plan to assemble and deploy MT synchronized array systems which are expected to have the power of flexible, modulized units that are easy to be repaired and exchanged in low costs. We have developed relative processing schemes and the software for dealing with the recorded raw data in our previous works. In our design of the land-based MT survey, we plan to conduct synchronized MT surveys in the western foothill area is the SW Taiwan, including the Choushuichi river, Chia-Yi, Taiwn, Kaoshuong and Pingtung regions. To better provide data from the missing marine area, we also plan to develop our MT systems for shallow marine explorations. It is our hope to resolve the detailed structure in the areas for better understanding the tectonic nature of this part of the Central to Southern Taiwan.
