摘要：This research aims to explore detailed spatial distributioncharacteristics, identify key factors weight, and establish anaccurate susceptibility regionalization model of coseismic landslidesby the Mw 6.6 Iburi, Japan, earthquake sequence of 6September 2018. Based on the remote sensing interpretation database,5,977 individual coseismic landslides were delineated, whichoccupies an area of about 15.26 km2. The relationship betweeneight key factors and spatial distribution of coseismic landslideswere precisely analyzed by the landslide area density (LAD) andlandslide point density (LPD) curves. In order to obtain the weightof eight key factors more accurately, this paper compares thesimilarities and differences of the two curves in the earthquakeswith similar magnitude, which was included the Lushan andJiuzhaigou earthquake in China. According to the weight of eightkey factors, the improved weight of evidence method was used toproduce the susceptibility regionalization map of coseismic landslidesin the Iburi earthquake. The results show that the improvedweight of evidence method has better precision and can provide ascientific coseismic landslides susceptibility regionalization mapfor disaster prevention and mitigation in the Iburi earthquake.
