Short summary

We studied how rainfall attributes and topography affected the hydrologic processes that triggered different types of landslides in unwelded pyroclastic flow deposits in southern Kyushu, Japan. Storms with higher intensities and drier conditions preceding the storm typically triggered landslides by rapid pore pressure response, while during small storms with lower intensity, landslides were influenced by the combined increase in soil weight and loss of suction.
