Volcanic Eruption Prediction: A Machine Learning Early Warning System Based on Seismic Time Series Features

Project Overview

eruption-forecast is an open-source Python framework maintained by martanto (GitHub link: https://github.com/martanto/eruption-forecast), with its core being a machine learning early warning system based on seismic time series features. It processes seismic tremor data, extracts statistical features (using the tsfresh tool), and trains an ensemble of multi-classifiers to achieve probabilistic early warning of volcanic eruptions. This method has been validated on New Zealand's Whakaari Volcano and supports transfer learning for application to other volcanoes with scarce data, positioning itself as a research tool.

Background and Challenges

Volcanic eruptions are highly destructive natural disasters. Traditional monitoring relies on manual analysis by seismologists, but volcanic systems are complex, precursor signals are weak and variable, and different volcanoes have large characteristic differences, making prediction difficult. In recent years, machine learning technology has brought new possibilities to volcanic monitoring: automatically extracting tiny patterns from seismic sequences to improve the accuracy and timeliness of early warnings.

Technical Architecture and Core Mechanisms

1. Data Preprocessing: Clean, denoise, and resample raw seismic data to ensure consistent quality;
2. Feature Extraction: Extract hundreds of features via tsfresh (time domain: mean/variance, etc.; frequency domain: Fourier transform components; complexity: Shannon entropy; trend features);
3. Ensemble Learning: Train multi-classifiers (random forest, gradient boosting, etc.) and generate results via voting to enhance robustness;
4. Probabilistic Output: Provide eruption probability and uncertainty quantification, reflecting the continuous change characteristics of volcanic activity.

Cross-Volcano Application of Transfer Learning

The project demonstrates the potential of transfer learning: models trained on Whakaari Volcano can be transferred to volcanoes with scarce data, enabling "one training, multiple deployments". This is of great significance for monitoring hundreds of active volcanoes worldwide that lack historical data, allowing resource-constrained volcanoes to also benefit from AI early warnings.

Practical Application Effects and Limitations

• Validation Effect: Successfully identified eruption precursors in monitoring of Whakaari and other volcanoes;
• Limitations:
  • Probabilistic prediction does not provide a deterministic guarantee, with risks of missed or false alarms;
  • Output needs to be interpreted by volcanologists and cannot be used alone as a basis for public safety decisions;
  • Positioned as a research tool, not an operational evacuation system.

Technical Implementation Details

• Modular Architecture: Includes modules for data processing, feature engineering, model training, prediction, evaluation, and visualization;
• Extensibility: Supports parameter adjustment via YAML configuration and can integrate Telegram for pushing early warning information.

Academic Contributions and Future Outlook

• Academic Foundation: Based on research such as Dempsey (2020) on automatic precursor identification for Whakaari and Ardid (2025) on transfer learning;
• Future Value: The framework integrates multiple technologies, laying the foundation for developing operational-level early warning systems, and is expected to contribute to global volcanic monitoring and protect residents' safety.
