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 you to apply online using the form below 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 role is part of a collaborative project with armasuisse Science and Technology and various partners from industry and the Swiss Armed Forces, contributing to the scientific foundation of monitoring and rapid alerting systems for underground infrastructure.

Project Background

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

The research will be conducted in close collaboration between BedrettoLab, operated by ETH, and the underground test facilities Hondrich, managed by armasuisse. The project is scheduled to span from 2026 to 2029 and will include 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., different types of seismometers as well as distributed acoustic sensing technology).
• Design and Installation of a Multi-Sensor Monitoring Network: Involvement in defining optimal sensor geometry, participating in field installations, calibrating velocity models using controlled test events, and ensuring quality control of data acquisition at the Hondrich underground test facilities.
• Algorithm Development: Integration of multi-sensor data streams into seismological software frameworks (e.g., SeisComP), conducting wave propagation modeling in complex 3D geometries, and developing optimized event detection algorithms and high-precision localization methods.
• Contributions to Cost-Optimized Alarm Systems: Engaging in cost-benefit optimization of reduced sensor layouts and collaborating closely with various stakeholders (engineering companies, Swiss Armed Forces, armasuisse, international collaborators) to ensure effective roll-out of the system.

Profile

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

Workplace

The candidate will be supervised by senior scientists at the Swiss Seismological Service, ETH Zurich, working within a multidisciplinary project consortium that includes public authorities and industry partners.

What We Offer

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