Landslides often occur in areas that are considered geologically vulnerable. Steep slopes and heavy rain are two major contributing factors to landslides, but there are other factors at play. From rock types to seismic activity, there are geological complexities that may increase the probability of a landslide occurring, but new research also points to human activity and climate as contributing variables.
