[DTC-E6] WF7601: Synthetic Shaking Workflow
Version 1

Workflow Type: Common Workflow Language
Work-in-progress

Overview

This workflow produces synthetic shaking simulations for historical earthquake events.
It integrates SeisComP, FinDer, and the Swiss, Italian, and European ShakeMap implementation to process continuous seismic data, estimate rupture parameters, and generate evolutionary shake maps.

In its full configuration, WF7601 is also capable of:

  • Sending event alerts when specific trigger conditions are met.
  • Pushing generated ShakeMaps to an external web portal for dissemination.

Note: In this distribution, both the alerting and ShakeMap publishing features are disabled.

The main CWL definition is provided in WF7601.cwl.
Workflow metadata follows the workflow-ro-crate-1.0 profile.

Workflow Structure

The workflow consists of the following datasets (DT) and software services (SS):

  1. Data Ingestion & Preprocessing

    • DT7601: Continuous seismic data (waveforms) from seismic stations. Replaced by a playback module to mimic data stream using past earthquakes.
    • SS7602: SeisComP – for seismic data acquisition and processing.
  2. Finite Fault Estimation

    • SS7603: FinDer – finite fault earthquake early warning algorithm.
  3. ShakeMap Generation

    • SS7601: Swiss, Italian and European ShakeMap – generates synthetic ground motion maps.
  4. Output Storage

    • DT7606: Evolutionary shake maps calculated at multiple update intervals between 0-60 s.
