Identification of Shallow Fault with Seismic Refraction Modelling in Gondang Area, Bojonegoro

Abstract There are various considerations in determining whether a field is said to have geothermal potential or not. One of them the appearance shallow faults area. This fault can function as permeable layer that used fluid flow path system. Due emergence manifestations around Mount Pandan Gondang area, Bojonegoro, seismic refraction measurements also needed support and validate area with hope visible through interpretation wave propagation velocity. measurement produces an anomaly thought be on track passes main fault, namely tracks 1, 2, 5, not far from manifestation Banyukuning hot spring. reinforced by direct observation surface conditions result faults.
