a A view from STD3-11 showing contact between granite in mountain and conglomerate further east. A depression in between is interpreted as a basin-bounding fault. b A view from STD3-10A showing the relationship between old and young alluvial fan units. A topographic break may indicate a normal fault. c, d Major surface rupture with left-lateral displacement close to Balaroa at STD3-08B and STD3-9B, respectively. e Minor surface rupture at STD3-10B showing left-lateral displacement. f Subsided surface on the beach at STD3-14
