[DTC-E4] WF7401: Dynamic Source Inversion Workflow

Version 1

Overview

This repository contains the Common Workflow Language (CWL) and RO-Crate metadata definition for WF7401, the Dynamic Source Inversion workflow of DTC-E4, developed under the DT-GEO project.

The WF7401 workflow performs dynamic source inversion of earthquakes using seismic and geodetic data. It prepares input data, executes high-performance computing (HPC) inversions, and extracts rupture models to characterize the physical parameters of earthquake sources.

The workflow leverages the FD3D_TSN inversion code, combining a quasi-dynamic boundary element solver and a Bayesian inversion framework with Parallel Tempering Monte Carlo to estimate model parameters and uncertainties.

Workflow Structure

1. Workflow Inputs

   • DT7401 – Dynamic Source Inversion Input: Input dataset including fault geometry, velocity models, and seismic and geodetic data from arrays of seismic and GPS stations.

2. Processing Steps

   • ST740101: Input data preparation and format standardization.
   • ST740102: Configuration of the FD3D_TSN inversion model.
   • ST740103: Execution of HPC-based inversion for rupture dynamics.
   • ST740104: Post-processing and extraction of rupture parameters (prestress, friction, misfits).
   • ST740105: Generation of final model products and metadata export.

3. Workflow Outputs

   • DT7402 – Dynamic Source Inversion Output: Model input parameters, rupture characteristics, and misfit statistics in text and binary formats.
