Heavy rainfall saturates surface topsoil until mudslides collapse building foundations. Strong seismic shaking increases water pressure in loose, water-saturated silt and sand, causing the soil to lose shear strength and behave like a liquid. Underground volcanic magma heats groundwater, turning solid soil into boiling mud pools. Subsurface tectonic fault movement physically splits the ground open and creates deep canyons beneath houses.
