Ngipik Landfill located in Gresik, East Java has a several active fault. Due to the condition, this area has high possibility of earthquake prone area. There is no bottom layer construction to prevent and control the leachate’s spread. This study aim to analyze the earthquake hazard map for the region based on the values of ground shear strain. The data was conducted by microtremor measurement and Plaxis modeling. The result of this study shows the shear strain value range between 3.5 x 10-3 to 12.5 x 10-3. The highest value is around the east and west-north area and indicated the high risk of damage under ground motion. The output of the research must consider as preliminary site mitigation of Ngipik Landfill.
