Abstract

One of the areas in Indonesia that are at risk of being affected by disasters is East Kalimantan. East Kalimantan is designated as IKN (State Capital City) by the government of the Republic of Indonesia. East Kalimantan was chosen as the new IKN due to its geographical location in the middle of the Indonesian archipelago and the low level of disaster risk. However, it is necessary to make efforts to mitigate disaster and to know the subsurface structure as initial information for making IKN. Integration of various scientific fields is needed to recognize disaster risks. One of the fields of science that is used is Geophysics. Methods in geophysics that describe the shape and the geological subsurface based on variations in the earth‘s gravitational are known as the gravity method. The data used is TOPEX Satellite observation data, in the form of FAA (Free Air Anomaly), a Complete Bouguer Anomaly Map obtained through Bouguer correction, and terrain that has been through adjustment of the range of values ​​of the correction to produce a representative map. The inversion modeling based on the complete Bouguer anomaly used in this study consists of two sections. By orienting at the epicenter of the earthquake as a reference. With contrast density from −0.863 mgal to 0.932 mgal. This indicates that there is an anomaly beneath the surface.
