A gravimetric study was performed at the Cerro Machin volcano (4° 29’ N, 75° 22’ W), Tolima Department, Colombia, to obtain a density distribution of volcanic edifice and its basement. This divided into three main sections. The first section consisted measurements on volcano, which were with Scintrex Autograv CG-5 gravimeter. In second section, complete Bouguer anomaly obtained by applying corr...

Geophysical research has been carried out using the gravity method on Adonara island in east Flores Regency, East Nusa Tenggara. This study aims to determine subsurface rock geological conditions of area free air anomaly data from GGMplus and ERTM2160. The is reduced by atmospheric correction, simple bouguer curvature correction produce a complete anomaly. After regional anomalies residual are ...

Depth analysis of the gravity anomaly source using Spectral Statistical Technique has been carried out in Godean area, Yogyakarta. This research was conducted to determine depth formation study area. used 56 acquisition points spread over 2 lines  along 12 km east-west direction. is from Complete Bouguer Anomaly profile. as a method determining by calculating slope graph Ln (PS) vs k. The resul...

We have investigated gravity anomalies around the Niigata plain, which is a sedimentary basin in central Japan bounded by mountains, to examine the continuity of subsurface fault structures of a large fault zone—the eastern boundary fault zone of the Niigata plain (EBFZNP). The features of the Bouguer anomaly and its first horizontal and vertical derivatives clearly illustrate the EBFZNP. The s...

Gravity data of Ceres returned by the National Aeronautics and Space Administration’s Dawn spacecraft is consistent with a lower density crust of variable thickness overlying a higher density mantle. Crustal thickness variations can affect the long-term, postimpact modification of impact craters on Ceres. Here we show that the unusual morphology of the 280 km diameter crater Kerwan may result f...

The new anomaly map images the high-density core of the CVC and the pronounced gravity low...

We estimated the dip distribution of Oita–Kumamoto Tectonic Line located in central Kyushu, Japan, by using the dip of the maximum eigenvector of the gravity gradient tensor. A series of earthquakes in Kumamoto and Oita beginning on 14 April 2016 occurred along this tectonic line, the largest of which was M = 7.3. Because a gravity gradiometry survey has not been conducted in the study area, we...
