Natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in Iran. Spotting such a high risk areas can help reducing the amount of their probable risk. A 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the Caspian Sea. This geotechnical hazard map divides the study area to 15 hazard classes (five and three hazard classes for liquefaction and landslide respectively). Removing negative factors affects the landslide hazard map, using effect analysis and reevaluating the accuracy of hazard map, increased the map accuracy by 93.5%. Based on the compiled geotechnical hazard map, about 30% of the study area is prone to low sliding and high liquefaction hazards.
