Creation of a Hazard Map Considering Regional Characteristics by Microtremor

Abstract

We always attempted to grasp the hazard considering the ground vibration characteristics of the area by a relatively simple method using the H/V spectrum ratio of the microtremor single point observation. We compared the dominant period peak obtained from HVSR of microtremor always with the dominant period peak obtained from strong motion observation and confirmed a certain degree of correlation. Therefore, as a hazard evaluation of the ground, we examined the applicability of hazard multiplied by Tm and Rm of HVSR. It was confirmed that the hazard map created is consistent with the AVS 30.
