碩士 / 國立中央大學 / 地球科學學系 / 103 / To better understand the submarine landslides off SW Taiwan, we have conducted multichannel seismic (MCS) reflection and chirp sonar surveys. We will use the collected data to analyze the submarine landslides in the Kaoping Slope and to understand the correlation between the submarine landslides and the mud diapirs.
The distribution of the bottom simulating reflectors (BSR) off SW Taiwan stops close to the major landslide areas where the gas hydrates start to dissociate. In addition, the study area consists of many mud diapirs. Submarine landslides generally occur near the summits of the mud diapirs or at their flanks. The upward motion of the mud diapirs may cause collapse of strata. Due to the mud diapirism, both sides of strata show a high angle tilt. Younger sediments show onlap structures, indicating that the region may be still active.
In the Kaoping Slope area, there are numerous creeping features. The shallow layer of creeping phenomenon indicates an unstable region, where submarine landslides may occur.
