2024 SCEC Dynamic Rupture Workshop

Benchmark for Getting to the Surface of the Problem

Date: November 4, 2024 (09:00 am – 04:00 pm Pacific Time)
Location: Online via Zoom
Workshop Organizers: Ruth Harris (USGS), Michael Barall (USGS)
SCEC Award: 24162

Overview

The 2024 SCEC Dynamic Rupture workshop will be convened in Zoom on November 4, 2024. This year our group has tackled the benchmark cases of simulating spontaneous (dynamic) earthquake rupture on a shallowly dipping fault near Earth’s surface. In benchmark exercise TPV36 the rupture reaches Earth’s surface, and in TPV37 the rupture stops before reaching Earth’s surface. At the workshop we will hear about new codes joining our group, and we will learn about the results of all of the modelers’ simulations for TPV36 and TPV37. We will also learn from the leaders of other related groups about what their science teams are working on. This workshop is, as always, about new discoveries for our dynamic-rupture community, so we will have a few slightly-longer invited talks, and an opportunity for any dynamic rupture scientist to present a quick overview of their new work in a 100-second lightning talk.

We welcome modelers interested in dynamic earthquake rupture simulations to attend our Zoom workshop. We especially encourage participation from students, postdocs, and early career scientists. Our participants are distributed across the U.S. and many countries worldwide, and the Zoom format allows more people to participate regardless of where they live.

SCEC-USGS Dynamic Rupture Verification Group

This SCEC-USGS group is an international collaboration that focuses on verifying computer codes used to simulate earthquakes as spontaneous dynamic ruptures. While the ultimate goal is model validation, we are currently using benchmarks to test for consistency of results under the same assumptions.

SCEC Activities Code of Conduct

The Statewide California Earthquake Center (SCEC) fosters a diverse and inclusive community where everyone feels safe, productive, and welcome. We expect all participants in SCEC-supported events to uphold this commitment by adhering to the SCEC Activities Code of Conduct.

SCEC Meetings and Workshops

The SCEC Annual Meeting brings together 400-500 participants worldwide to share breakthroughs, assess progress, and chart a collaborative path for earthquake science. All of the Center activities are presented, analyzed, and woven into a set of priorities for SCEC to pursue in the future.
