N2  - Research has been carried out on the subsurface structure in the Mount Kelud area based on the gravity method. The data used is data from Topex/Poseidon satelite. The purpose of this study was to determine the subsurface structure and magma chamber of Kelud Volcano. The gravity method can be used to model the subsurface conditions of a mountain or other area on earth. Data analysis was carried out by calculating Bouguer anomaly correction, flat plane reduction and separation of regional and residual anomalies using the band pass filter method. Interpretation is carried out with A-B sections. In this study, the magma chamber was modeled in 2.5 dimensions. The modeling results show that Mount Kelud consists of three layers. The first layer has a density of 2.6 g/cc, the second layer has a density of 2.7 g/cc, and the third layer has a density of 2.8 g/cc. The magma chamber is allegedly the third layer with a density of 2.6 gr/cc. The location of the magma chamber is estimated to be at a depth of ± 900m to ± 1800m below sea level.
