Abstract

Dimensionality and regional strike in Nyalindung segment, Cimandiri fault zone, Wes Java, Indonesia is determined using phase tensor analysis from audio frequency magnetotelluric (AMT) data. The AMT data acquisition has been carried out along 26 km profile with 24 AMT observation points. The result presents that the skew angle is -3° ≤ β ≤ 3°. The skew angle can be applied to determine the dimensionality of the study area. Besides, the rose diagrams of the phase tensor analysis show that geoelectrical strike of the study area dominated to be northeast-southwest direction with N80° E. It indicates the regional structure of the study area could be assumed as two dimensional and the calculated regional strike agree well with the previous studies.
