Earthquake Engineering
Aleatory variability refers to the inherent randomness or uncertainty in a system, often associated with natural phenomena like earthquakes. This variability stems from the unpredictable nature of seismic events, leading to different ground motion outcomes even under similar conditions. Understanding this concept is crucial when assessing seismic hazards and predicting ground motion, as it directly influences hazard curves and uniform hazard spectra, which represent the probabilistic aspects of earthquake risks.
