Microtremor data and HVSR method in the kaligarang fault zone Semarang, Indonesia

Abstract

The data presented contains a collection of microtremor measurement data in the Kaligarang Fault zone, Indonesia. This study aims to present data regarding the structure and lithology of the rocks in the Kaligarang Fault zone. Data was obtained using a triaxial geophone VHL PS 2B and recorded with a data logger type GL 240 with a duration of 10 minutes. The data in this study are primary data taken using a single-station microtremor device with a total of 75 acquisition points in the Kaligarang Fault zone. This data can then be used in the analysis of the Horizontal to Vertical Spectral Ratio (HVSR) which will later produce the hv curve. The vp, vs, density and thickness profiles of each data were obtained from carrying out the inversion process using dinver.
