Date: Wednesday, November 12, 2025 1:00 PM - 2:00 PM - “A Non-Ergodic Ground Motion Model for the Groningen, Netherlands: Merging Physics-Based Simulations and Empirical Observations”. We present a new non-ergodic ground motion model (GMM) for the Groningen natural gas field in the Netherlands, aimed at improving the region's seismic hazard characterization. Non-ergodic GMMs offer the ability to reduce aleatory variability, which often controls the seismic hazard, especially at longer return periods. Further details provided at the seminar.
