Indonesia is zone of 4th active plates interaction over the world: Eurasia Plate, Indo-Australia Plate, Pacific Plate and Philiphine Plate. From it???s tectonic actifity, found some area which involved the earthquake disaster gristle area, one of them is Singaraja, Buleleng Regency, Bali. From north Bali there???s back arc fault along from Bali sea, north Lombok until Banda sea. The resulted earthquake is from shallow depth so if the earthquake have a high magnitude will cause a damage. The effective method is needed for minimize the risk caused by earthquake like microzonation using microtremor measuring. The recording microtremor is conducted by using HVSR (Horizontal to Vertical Spectral Ratio) method for analyze it???s impact a location considering the seismic wave response from soil layer or sediment concerning the existence of earthquake. The measured result is dominant frequency which used for calculate S waves velocity at 30 meter depth (Vs30) and amplification. Based on the overlay result from those values, we summarized that the area that have a high disaster gristle area is the south-western research area.ududKeywords: Microtremor, Microzonation, vs30
