Abstract

The Analysis of total magnetic field anomaly data research of Rajabasa volcano area has been done to obtain the
information of the fault area direction. This research is done by the use of geomagnetic method by conducting the
measurement of magnetic field intensity on the surface of earth. The IGRF correction and daily variation are conducted
to obtain anomaly magnetic field from the rock due to under surface respond. Based on the map of total contour anomaly
magnetic field at level surface showed an interesting anomaly rock respond on the direction of south of measurement
area (manifestation of Simpur and Wartawan coast), on the direction of northwest area (crater of Sukamandi village), the
north area (Kecapi crater) and the midst area (mount and crater Rajabasa volcano). These responds are indication of the
existence of fault with the direction to the northwest-southeast as geothermal fluid flow area to the earth surface.
Key words: Rajabasa volcano, fault, magnetic field anomaly, geothermal
