[DTC-E4] WF7402: Kinematic Inversion Workflow

Version 1

Overview

This repository contains the Common Workflow Language (CWL) and RO-Crate metadata definition for WF7402, the Kinematic Inversion workflow of DTC-E4, developed under the DT-GEO project.

The WF7402 workflow performs automatic kinematic source inversion using seismic and geodetic data to produce slip models and kinematically-informed dynamic rupture simulations. It integrates multiple data sources and inversion tools to reconstruct the spatial and temporal evolution of fault slip during an earthquake event.

This workflow supports rapid, automated inversion following real or simulated earthquakes, contributing to the DT-GEO digital twin framework for dynamic earthquake modeling and validation.

Workflow Structure

1. Workflow Inputs

   • DT7403 – Seismograms, GPS offsets, Fault geometry, and Velocity model: Input dataset including fault geometry, velocity models, and seismic and geodetic observations from arrays of seismic and GPS stations.

2. Processing Steps

   • ST740201: Input data ingestion and preparation.
   • ST740202: Fault geometry and velocity model setup.
   • ST740203: Execution of the kinematic inversion using the SLIPNEAR inversion code.
   • ST740204: Model validation and generation of slip distribution results.
   • ST740205: Post-processing and export of kinematically-informed dynamic rupture models.

3. Workflow Outputs

   • DT7404 – Kinematic Slip Model: Slip distribution and model predictions from the inversion process.
   • DT7405 – Kinematically-informed Dynamic Rupture Model: Dynamic rupture simulations derived from the kinematic results.
