PhD Researcher in Seismic Detection, Localization and Characterization of Explosion Events in Underground Ammunition Storage Facilities

PhD Position: Seismic Detection, Localization and Characterization of Explosion Events in Underground Ammunition Storage Facilities

100%, Zurich, fixed-term

The Swiss Seismological Service (SED) at ETH Zurich invites applications for a PhD position within a multi-year applied research project focused on the detection, localization, and interpretation of explosion events in underground ammunition storage facilities. This position is part of a collaborative initiative with armasuisse Science and Technology, industry partners, and the Swiss Armed Forces. The research aims to strengthen the scientific foundation for monitoring and rapid alerting systems for underground infrastructure.

Project Background

Seismic and fiber-optic sensing technologies present promising solutions for the real-time detection, localization, and characterization of explosions and related hazardous events in underground settings. The project aims to evaluate sensor technologies, design and optimize multi-sensor monitoring networks, and develop advanced detection and localization algorithms tailored to complex 3D underground geometries.

Research will be conducted in close collaboration between BedrettoLab, operated by ETH, and the underground test facilities at Hondrich, managed by armasuisse. The project spans from 2026 to 2029 and includes experimental campaigns, field installations, data collection, data processing, algorithm development, and system optimization.

Job Description

• Experimental Campaigns and Sensor Evaluation: Design and analysis of controlled test explosions in the BedrettoLab, evaluation of seismic sensors (e.g., various types of seismometers and distributed acoustic sensing technology).
• Design and Installation of a Multi-Sensor Monitoring Network: Define optimal sensor geometry, participate in field installations, calibrate velocity models using controlled test events, and ensure quality control of data acquisition.
• Algorithm Development: Integrate multi-sensor data streams into seismological software frameworks (e.g., SeisComP), perform wave propagation modeling in complex 3D geometries, and develop and optimize event detection algorithms, high-precision localization methods, event magnitude assessments, and source characterization techniques, contributing to real-time alarm system implementation.
• Contributions to Cost-Optimized Alarm System Implementation: Optimize reduced sensor layouts for cost-efficiency, develop user-friendly monitoring concepts for future underground facilities, and collaborate closely with stakeholders (engineering companies, Swiss Armed Forces, armasuisse, and international partners) for effective system rollout.

Profile

• MSc degree in Geophysics, Seismology, Earth Sciences, Physics, Engineering, or a related field.
• Strong quantitative, analytical, and programming skills (Python required; experience with seismic data processing is advantageous).
• Initial experience in seismic data analysis and/or wave propagation modeling is desirable.
• Willingness to participate in field campaigns in underground facilities.
• Genuine interest in field experiments and applied research.
• A practical mindset for efficient project implementation.
• Motivation to thrive in an interdisciplinary and practical environment.

We Offer

• A fully funded PhD position (up to 4 years).
• Employment in accordance with ETH Zurich regulations.
• Access to the Bedretto Underground Laboratory.
• A collaborative environment bridging research, field experiments, and real-world applications.
• Opportunities for publications and international conference participation.
• Excellent analytical and strong communication skills, ideally in both German and English.

Supervision and Environment

The candidate will receive supervision from senior scientists at the Swiss Seismological Service, ETH Zurich, and will work within a multidisciplinary project consortium, including public authorities and industry partners.
