Qualitative interpretation of Bouguer anomaly in the southern part of the Korean peninsula

Regional gravity anomaly maps of Korea have been used for geologic information on the nature of crust and isostasy. We made an attempt to interpret the Bouguer map based on the nature, quality, and characteristics of anomalies and integrate the data with the geologic and tectonic features. Seismicity is also considered for the correlation with the Bouguer map. It reveals that the gravity anomaly map helps delineate major tectonic boundaries. It is observed that the gravity high zones are associated with earthquake activity and lineaments in their proximity.
