Geothermal studies to identify the flow of hot water in Natar, Lampung using gradiometer

Abstract

Natar hot spring is one of the unique hot springs in Lampung. These springs are far from volcanoes but have geothermal manifestations. The purpose of this study is to explain the distribution and flow of Natar hot water under the manifestation of hot springs. The method used in this research is the magnetic method using a combination of the magnetometer and gradiometer. The number of measurement points is around 102 points, with a distance between points about 25 m. Data processing is with use 3D magnetic model. The results obtained are the hot water flows from the high anomaly area to the low anomaly area. High anomaly caused by rock no content hot water because hot water moves to a low anomaly area.
