Abstract

Determination of East Kalimantan, particularly Sepaku Sub-District, Panajam Paser Utara Regency, and Kutai Karta Negara Regency as the New Capital City of Indonesia requires an in-depth and comprehensive study of various aspects, including the natural disaster of the earthquake. Based on earthquake records for the last 11 years, East Kalimantan is the province with the highest level of seismicity in Kalimantan Island, and nationally it occupies 26th rank. The existence of the local Meratus fault needs to be watched for because it lies beneath the land and is relatively active. It has the potential to damage areas with high seismicity levels. The potential for earthquake damage can be minimized by constructing earthquake-resistant infrastructure. The construction of earthquake-resistant infrastructure can be started by studying soil dynamics properties in the area, like natural frequency and peak ground acceleration. This research was conducted by applying the Horizontal-to-Vertical Spectral Ratio (HVSR) method to analyze both properties to calculate the vulnerability index through a microzonation study. The HVSR method is comparing the ratio of the spectrum of the horizontal component of the microtremor signal with its vertical part. The HVSR method utilizes the natural harmonic vibrations of the soil caused by natural activities. The result of the research on the study area shows an index of seismic vulnerability ranges from 0.2 to 2.1.
