Distribution of Mud Volcanoes and related seafloor features Off Southwestern Taiwan
Presenter：Hsueh-Fen Wang Adviser： Shu-Kun Hsu
Abstract
Mud volcanoes and related seafloor features have been identified along chirp sonar and seismic reflection profile data of southwestern Taiwan. Widely distributed BSRs and these related seafloor features extending from the accretionary wedge to the passive China continental margin. Active fluid activities are evident from various features observed on seismic reflection and chirp sonar profiles, such as mud volcanoes, gas plumes and Gassy Sediments in the shallow sedimentary layers. Submarine mud volcanoes could be grouped into four main clusters in the accretionary wedge province: offshore Kaohsiung, adjacent to the Kaoping Submarine Canyon, near the head of the Fangliao Submarine Canyon and along the Yung-An Lineament.
