Abstract: Noise Tomography is one of geophysical passive seismic method to utilize a coherent ambient noise who created naturally due to presence of the rotation of the earth (sea wave, gust wind, water movement that produces vibration) to detect discontinuity of wave (based on velocity measurement that correlated at multiple station) on inhomogeneity medium to determine the physical properties of rock from subsurface. In this research, we used 20 unit of Lennartz 3D-lite short period seismometer with Taurus Digitizer and record 24-72 hours on 22 days at TFQ1 Geothermal Field. Then, we process the data with several techniques to correlate recorded data on the station such as pairing technique, clustering technique and ring creation techniques on PertaGAMANT (Pertamina’s software). Result of 1D velocity model in this research can be used to determine a subsurface permeability of rock on geothermal field.
