Abstract
The landslide disaster occurred during the rainy season in Kebomas District, Gresik Regency, which has
topography in the form of hills left over from lime mining in 1960-1990. A field survey conducted from
December 2021 to March 2022 stated that landslides occurred during the rainy season in Kebomas District and
caused damage to surrounding settlements. Land slope, rainfall, rock type, soil type, and land use are factors
that influence the occurrence of landslides. The aim of this research is to map the level of landslide vulnerability
in Kebomas District using the Geographic Information System. The research results show that there are three
levels of landslide vulnerability in Kebomas District, namely, low, medium and high. The low vulnerability class
is found in all villages in Kebomas District, most of which are in six villages or sub-districts in the south, west
and north, namely; Dahanrejo, Kedanyang, Pambangan, Kembangan, Randuagung, and Segoromadu. The
moderate vulnerability class is found in all villages in Kebomas District, most of which are in six villages in the
southeast, northwest and north, namely; Randuagung, Pambangan, Dahanrejo, Kembangan, Sidomoro, and
