2026 SCEC Dynamic Rupture Workshop
The SCEC Dynamic Rupture Group is convening a Zoom workshop on October 14, 2026. The theme is the ShakeOut2.0 large aftershock scenario, along with new findings from dynamic rupture simulations of earthquake source behavior. The workshop will introduce a new benchmark exercise for community verification of dynamic rupture codes.

Dynamic rupture simulations are useful tools to help us better understand how earthquakes work and how they generate ground motions. Nowadays dynamic earthquake rupture codes are used by dozens of researchers around the world to increase our knowledge about earthquakes which occurred in the past, and to create scenarios of earthquakes of the future. Dynamic rupture simulations are the sister computations of their more commonly used counterparts, kinematic rupture simulations, but dynamic rupture simulations are more complex and need more assumptions about rock properties and the physics of faulting.

The ShakeOut Scenario 2.0 is a collaborative effort to develop updated earthquake scenarios using current scientific understanding and engineering capabilities. As part of this effort, our group is simulating a large aftershock on the Hollywood-Raymond faults in the Los Angeles Basin. During our workshops in the early-2020’s, we examined the four key ingredients for dynamic rupture simulations. At the 2026 workshop, we will introduce the ShakeOut Scenario 2.0 aftershock benchmark, a high-impact earthquake scenario that will be used to test our codes and assess whether their results are repeatable. Using shared model inputs, independently developed codes will test whether they produce consistent earthquake-source and near-field ground-motion results. The workshop will explain the benchmark’s scientific basis and participation process, share related research, and identify next steps for the community verification effort.

We welcome dynamic rupture modelers and others interested in earthquake rupture simulations. Participants at all career stages—from graduate students and postdoctoral scholars to early-career and established researchers—are encouraged to attend. We also welcome colleagues from the United States and around the world to foster broad exchange and collaboration.
