Every other day one earthquake occurs in a more or less expected location. It might be along a well-known and well-mapped fault or, conversely, along a fault that went unnoticed, possibly due to a very slow deformation rate. Thus, addressing risk only in the perspective of earthquake hazard assessment might be difficult and a complementary approach, the fault displacement hazard assessment is gaining weight. For this approach to be efficient, however, it needs a good understanding of the surface rupture patterns and ground deformation during earthquakes in relation with fault geometry. In this talk, I will be presented some recent results addressing earthquake surface rupture, localized versus diffuse deformation, and scaling of fault geometry, derived from a combination of field observation and space geodesy.
