Geological scratches on the other hand have a name called Slickenlines. They work as very good indicators of slip on a fault plane. Geologists have used these lines for decades to identify the movement of the rock block along a fault. We, a group of researchers at Jadavpur University and IIEST in India trying to associate these lines with domains of seismic slips during an earthquake event. Our idea demonstrates the fault plane as a heterogeneous slip zones. These zones are distributed on the rupture plane either as isolated patches or connected patches of slips. Depending upon this heterogeneous distribution of slip, the plane develops heterogeneity in terms of their roughness. Our study quantifies this degree of roughness in both 1D and 2D space in terms of Fractional Dimension or Fractal Dimension (D) using image processing techniques in MATLAB.
