There are of course many journals that deal with landslide susceptibility studies. But I guess a good starting point would be to look at the list of references you have and select a journal that published the authors you are citing.
Of course many choices are possible, which also depend on the level of novelty of your studies. Among them, for sure Landslides is one good journal that focuses on all aspects of landslides. No other journals are so focused on landslides, as far as I know. Within the more general context of engineering geology, you may also consider the official journal of the IAEG, the Bulletin of Engineering Geology and the Environment. It seems to me a good choice too.
