The surface ruptures during earthquakes are invaluable information on the subterranean slip and rupture process. Recent progress in image analyses and laser scanning techniques innovated high-resolution three-dimentional mapping of the ruptures. We firstly examine the high-precision mapping of recent and past surface ruptures and discuss about the way to develop the technique. Secondly, the relationship of the earthquake source processes, strong motion generation, and geologic structure with observed surface deformation is an important unsolved issue. We still do not know much about correlation of slip at depth with slip at surface and about generation of seismic waves above seismogenic zone. Fault displacement hazard assessment is a new challenging technique that follows far behind the bivratory seismic hazard assessment of strong ground motions. Ongoing development of the fault displacement hazard assessment will be discussed together with the surface rupture database of past earthquakes.
