Exceedance (Noun)
Meaning
(geology) the probability that an earthquake will generate a level of ground motion that exceeds a specified reference level during a given exposure time; "the concept of exceedance can be applied to any type of environmental risk modeling".
Classification
Nouns denoting attributes of people and objects.
Examples
- The exceedance probability is calculated based on the historical seismic activity in the region and the building's design specifications.
- The study aimed to quantify the exceedance of a certain level of ground shaking that could lead to significant damage to infrastructure.
- To assess the seismic hazard, engineers use the concept of exceedance to estimate the likelihood of exceeding a specified peak ground acceleration.
- Exceedance curves are commonly used in earthquake risk modeling to visualize the probability of exceeding different levels of ground motion.
- The model predicts the exceedance probability of a certain level of liquefaction during an earthquake, which can inform the design of foundation systems.
