Probabilistic Seismic Hazard Assessment (PSHA)

Probabilistic Seismic Hazard Assessment (PSHA) is a method used to estimate the likelihood of different levels of earthquake shaking at a location over a specific period. It considers all possible earthquake sources, their sizes, how often they occur, and how seismic waves travel through the earth. By analyzing these factors, PSHA provides a probabilistic understanding of earthquake risks, helping engineers and planners design structures and develop policies that are resilient against seismic hazards, ultimately reducing potential damage and enhancing safety in earthquake-prone areas.
