Microtremor data and HVSR method of geothermal manifestation of Mt. Telomoyo, Central Java, Indonesia

Abstract

The data presented contains a collection of microtremor measurement data regarding the structures and fluid flow of the Mt. Telomoyo's geothermal manifestation, Indonesia. The data are primary data taken using 3 unit single-station microtremor devices with a total of 60 acquisition stations in The Umbul Temple, Dukuh Temple and Pakis Dadu hot spring manifestation area. Data was obtained using 3-component digital seismograph VHL PS-2B series and recorded with a data logger type GL 240 with a duration of 10 min. 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 compressional wave velocity vp, shear wave velocity vs, density, and thickness profiles of each data were obtained from carrying out the inversion process using Dinver.
