[DTC-E1] WF7103: Computational Hazard

Version 1

Overview

This repository contains the Common Workflow Language (CWL) and RO-Crate metadata definition for WF7103, the Computational Hazard workflow of DTC-E1, developed under the DT-GEO project.

The WF7103 workflow performs probabilistic seismic hazard computations by combining seismogenic source models with computational hazard software. It integrates outputs from the Seismogenic Source Models Workflow (WF7102) and base datasets such as the 2020 European Seismic Hazard Model (ESHM20) to produce hazard maps and related outputs that quantify ground-shaking probabilities across regions.

Workflow Structure

The workflow follows a modular structure, using standardized datasets (DT) and computational steps (ST) to run regional-scale seismic hazard simulations.

1. Workflow Inputs

   • DT7104 – Seismogenic Source Model of the 2020 European Seismic Hazard Model (ESHM20).
   • DT7108 – Updated Seismogenic Source Model generated by WF7102.

2. Processing Steps

   • ST710301: Prepare input model configurations and hazard parameters.
   • ST710302: Run seismic hazard simulations using the OpenQuake engine.
   • ST710303: Post-process hazard outputs (e.g., ground motion fields, hazard curves).
   • ST710304: Validate and archive the results for subsequent risk modeling (WF7104).

3. Workflow Output

   • DT7109 – Seismic Hazard Results containing probabilistic ground-shaking maps, hazard curves, and summary statistics.
