It was established that the method could estimate the dip angle of a fault or structure boundary and that it could recognize the difference between a normal-fault type boundary and a reverse-fault type boundary. As an application with field data, we applied the method to the Bouguer gravity anomaly in and around the area from Iyo-Nada, across Beppu Bay to the Hohi volcanic zone.
