Abstract

Abstract

High-resolution bathymetry and subbottom profile data have been acquired in the northern Luzon Trough, a landslide extended on an area of 500 km², more than 20 m thick has been found in the middle trough. According to the analysis of landslide source and its sedimentary environment, the landslide is divided into two parts: an end area and a front area. From the relationship between the landslide area and the surrounding stratum and the history of the volcano eruption, it is suggested that the submarine landslide is triggered by the earthquake. Most submarine landslides occur in the depth range of 2 000 m, while the average depth of the study area is more than 3 000 m, thus the discovery of the submarine landslide is significant in deepening the research of the deepwater landslide.
