Fig. 6.Close-up view to the lava dome of Merapi from radar imagery. A pronounced fracture is splitting the dome into two halves. E, F. Composite raster map images created in the RGB
bands for R = pre-explosive and G = post-explosive imagery (B—blank) depicts changes and lengths of newly formed fractures. The main fracture is defined by two sub-fractures with a
slightly different azimuth, each about 100 m long. The rose diagrams show the strike angles of the lineaments (white arrows in E and F) within the crater. Note the change in the southern
dome are
