Short summary
Seismic hazard evaluation is required for establishing earthquake-resistant building codes. Our aim is to improve the quantification of seismic hazard in the Levant by including our knowledge on how faults may be interconnected. We build an earthquake forecast by redistributing the energy stored in the fault system over all possible earthquake ruptures. This interconnected fault model leads to seismic hazard maps where hazard is as high on secondary fault branches as on main branches.
