[DTC-E3] WF7301: Ground Motion Models

Version 1

Overview

This repository contains the Common Workflow Language (CWL) and RO-Crate metadata definition for WF7301, the Ground Motion Data Processing and Hazard Product Generation workflow of DTC-E3, developed under the DT-GEO project.

The WF7301 workflow automates the collection, processing, and validation of ground motion data to produce updated hazard and risk products. It integrates observational datasets with computational tools for model calibration, anomaly detection, and intensity model testing.

The workflow supports both real-time and historical seismic data ingestion, providing consistent data products for subsequent digital twin simulations and validation efforts.

Workflow Structure

1. Workflow Inputs

   • DT7301 – Observed Ground Motion Data: Ground motion waveforms and intensity measurements from ORFEUS (ESM, RRSM, EIDA).
   • Simulation Dataset: Synthetic ground motion simulations generated from computational models.

2. Processing Steps

   • ST730101: Data ingestion and preprocessing using Stream2Segment.
   • ST730102: Ground motion intensity calculation and statistical correction.
   • ST730103: Model validation and ground motion prediction testing with eGSIM.
   • ST730104: Seismic anomaly detection using SDAAS (Simple ML tool for anomaly scoring).
   • ST730105: Integration of observed and simulated data for hazard and risk product updates.

3. Workflow Outputs

   • DT7303 – Hazard and Risk Products: Processed and validated datasets containing ground shaking intensities, hazard curves, and derived risk products.
