- Through a large-scale case study, we introduce a technique to define rainfall threshold for slope failure in weathered tephra deposits. Excessive rainfall increases soil pore water pressure and reduces effective stress. Landslide occurrence in weathered tephra deposits is largely related to excessive rainfall events. Knowing the threshold where rainfall events would impose risk to slope failure in weathered tephra deposits, authorities could introduce mitigating measures (e.g. early warning systems) to inform proximate residences to evacuate the area, saving lives. Also, by knowing the threshold and average annual rainfall of an area, landslide prone areas could be avoided for future developments.
