Abstract

This research of microtremor was conducted to determined seismic vulnerability index at Kepahiang district. The purpose of this research was to know seismic vulnerability in Kepahiang district based on dominant frequency, dominant period and amplification. The measurement of microtremor was did at 45 points that spreading at Kepahiang district. Data of the microtremor was analyzed by HVSR (Horizontal to Vertical Spectra Ratio) method. From this method will obtained the important parameters were dominant frequency and amplification.The result show that highest seismic vulnerability index of 49,75 is at point 38. Based on classification of seismic vulnerability index, there was 3 zones such as low, middle and high zone. There are 19 points of the measurement in the low seismic vulnerability zone, with seismic vulnerability index range up 0,79 to 2,80. Temporary the point of middle zone was 13 points with seismic vulnerability index of 3,26 to 5,13. For high zone, there was 15 points that seismic vulnerability index range up 6,39 to 49,75.
