A. Sunmonu, V. P. Dimri] —The Koyna-Warna region has been shaken by several earthquakes greater than magnitude 4 in the last 35 years. Four of them in 1967, 1973, 1980 and 1993, were potentially very destructive with magnitudes exceeding 5.0. The majority of seismic events recorded to date has been induced from Koyna-Warna reservoir areas. This paper discusses the fractal analysis of a fault map from LANDSAT images with the increasing seismic activity in the region. The region is divided into six blocks and the fractal dimension of each block is calculated using a box-counting technique. A plot of a three-dimensional map of the fractal dimension is prepared. It shows that the value of the fractal dimension is gently dipping from NE to SW. The fractal dimension is used to estimate the b-value in the frequency-magnitude relation of earthquakes in the region which is in agreement with earlier studies.
