Project Abstract
 Quakeworx is an NSF-supported science gateway, led by SCEC researchers, that provides web-based access to advanced earthquake-research applications running on national high-performance computing (HPC) and cloud resources. This SCEC award supported targeted enhancements to the OneSciencePlace cyberinfrastructure underpinning Quakeworx, with the goal of integrating compute resources beyond the San Diego Supercomputer Center (SDSC) — specifically TACC Frontera, NCSA Delta, and IU JetStream2 — to support a broader range of SCEC science workflows including post-event UCERF3-ETAS forecasting, GPU-accelerated machine learning, and persistent cloud workspaces. Over the project period, the team built a staging gateway on OneSciencePlace with interactive (Jupyter, VNC) and batch app support, integrated single sign-on via Globus, deployed nine containerized SCEC science apps (Broadband Platform, HFQsim, Moose-FARMS, pyCSEP, QuakeNN, SeisSol, Tandem, UCERF3-ETAS, UCVM with CVM-H), and added job-provenance tracking together with an advanced UI builder for app creation. Community engagement included a January 2025 kick-off workshop training 65 selected participants from more than 150 applicants representing 16 countries, with subsequent open access reaching 1,300+ users, and a July 2025 Tandem Hackathon.
Intellectual Merit This project advances open, reproducible, FAIR-aligned cyberinfrastructure for the SCEC community by extending the OneSciencePlace platform to support the heterogeneous compute needs of modern earthquake research, leadership-class CPU systems, large GPU systems, and cloud VMs. Containerized science apps with Tapis-based job submission, provenance tracking, and reduced-order modeling workflows lower the technical barrier to running complex simulations and enable rapid-response computing scenarios such as post-event UCERF3-ETAS forecasting and CyberShake-style physics-based hazard analysis. The Tandem and SeisSol app integrations give SCEC researchers a low-friction route from idealized benchmarks to data-constrained scenario simulations on national HPC.
Broader Impacts Quakeworx makes advanced earthquake-simulation tools accessible to a broad community of researchers, students, and educators. The January 2025 kick-off workshop reached 65 hands-on participants from 16 countries selected from more than 150 applicants; training materials have since been accessed by over 1,300 users. The July 2025 Tandem Hackathon expanded the contributor base for the Tandem code through GPU-development tracks, benchmark contributions, and co-authorable publications. Quakeworx apps have been integrated into the Advanced Seismology course at UC San Diego, with new teaching materials for seismology curricula, and the team is planning use cases for secondary education through inquiry-based experiments on rupture directivity and shaking amplitudes.
Project Participants This award was initially led by Amit Chourasia (UCSD/SDSC), with Philip J. Maechling (SCEC/USC) as unfunded co-PI. Following Chourasia's transition out of SDSC during the project period, leadership of the SCEC reporting and remaining deliverables was assumed by Alice-Agnes Gabriel (UCSD/SIO), now UCSD PI of the broader Quakeworx project. The work described below was carried out by the SIO team, students John Rekoske, Jeena Yun and postdoc Bar Oryan, and the SDSC engineering team in close collaboration with SCEC software staff (F. Silva, A. Bhatthal) and SCEC science-app PIs across UCSD, USC, UIUC, and UCLA.
