英文摘要	Tegucigalpa, the capital city of Honduras, has the highest number of landslides recorded in the country. The city has data and information from four landslide inventories and five landslide susceptibility studies, with different methodologies and results. In this research, the four existing landslide inventories were compared, and a new inventory was developed. The importance of four data layers (lithology, slope, distance to streams, and colluvium map) in explaining landslide occurrence was analyzed using the weight-of-evidence method, including the colluvium map developed in this research. A new landslide susceptibility map based on the colluvium map was produced, and its accuracy estimated using the success rate curve method. The accuracy of the landslide susceptibility map based on the colluvium was 88.64%, compared with the 79.79% and 69.80% of previous studies. This study emphasizes the relevance of colluvium mapping as an input for landslide susceptibility analysis in Tegucigalpa. © 2020, Springer Nature B.V.
