The seismic geohazard microzonation along Muzaffarabad Fault is based on hazard parameters such as active faults, active rupture zone, unstable steep slopes, brittle shear zone, active old and new landslides, ground shaking, earthquake deformation, seismic amplification, seismicity and flood.
Paradoxically, advances in technology can increase society's Vulnerability because of reliance on distant resources and just-in-time inventory delivery, with the result that the economic impact of a natural hazard event can be broader than its storm track or rupture zone.
