In order to receive the signal from the seismic airgun released by seismic ship of Fujian Earthquake Agency, ocean-bottom seismometers were deployed in southern Taiwan Strait since 2015. Based on the data, we can use refined sedimentary structure picture to analyze the Binhai fault zone. The next year, we found upwarping of the Binhai fault zone between Dongshan land bridge and Cenozoic depression. Same happened at the Dongshan fault between Cenozoic depression and Taiwan Banks. From 2017, 10 ocean-bottom seismometers began to receive signal from Ocean Researcher 2. With all the data, we established the sedimental speed model, along with the crustal velocity structure model of Taiwan Strait.
