Statistics and Probabilities in fault based seismic hazard models: a primer
Monday 13th June 2022 14:00 CET (13:00 UK, 14:00 Italy/France)
Fault based seismicity models are currently practiced for probabilistic seismic hazard assessment (PSHA). Geologic, geomorphic and paleoseismic data represent important inputs to the most common fault based seismic hazard model, as they can characterize the magnitudes, locations, and occurrences over long time intervals (thousands of years). To develop these models, we routinely make use of statistical approaches (note physics based models are not the topic of this lecture). Many models and data sources are combined to create fault based PSHA and the overall approach can seem opaque to beginners or non-specialists. However, when examined, fault based models in particular, and PSHA in general, are rather intuitive and flexible enough to accommodate a variety of users’ needs. Probability calculations are a critical part of the entire workflow, so a basic knowledge of most common functions and statistical procedures is provided for interested participants.
