The invention relates to a landslide early warning method and device, computer equipment and a storage medium. The method includes the steps of obtaining terrain phase information and earth surface deformation phase information of an urban slope; determining a potential landslide area according to the terrain phase information and earth surface deformation phase information; monitoring surface anddeep portion displacement information, stress and strain information and geological and hydrological conditions of the potential landslide area to obtain monitoring data; conducting early warning analysis on the monitoring data by an early warning model to obtain an early warning indicator of the potential landslide area, wherein the early warning indicator is used for indicating the safety degree of the potential landslide area. By means of the method, quick and effective early warning can be conducted on the potential landslide area.
