Summary of the doctoral project:

The core scientific problem this project seeks to address is the need to evolve the current paradigm of how OBS data are acquired during academic seismic surveys and how they are routinely processed. A key limitation of these surveys (from the perspective of modern processing techniques such as full-waveform inversion – FWI) is the sparse receiver deployments, which result in insufficient illumination of the target, as well as a lack of multi-azimuthal coverage from typical 2D profiles. This situation persists despite the availability of well-established imaging algorithms supported by advanced computing power, which are capable of generating high-fidelity regional geological models but cannot be fully exploited without optimized OBS data. While this suboptimal data acquisition is partly due to budgetary and time constraints in academic surveys, we may also argue that the prevailing practice of sparse 2D OBS deployments has led to the widespread use of computationally inexpensive traveltime inversion, which allows to quickly generate a range of smooth velocity models that fit the traveltimes with similar kinematic errors. This approach does not drive progress toward better-optimized data acquisition. Instead, academic surveys should be designed to meet the demands of modern processing techniques and, where necessary, improve the conventional approaches.

From a seismic survey perspective, “optimal OBS acquisition” refers to a set of key parameters – such as survey geometry, source/receiver configurations, etc. – that will allow for the best possible reconstruction of the target. Therefore, it must be tailored to the method, target, and available resources. But is it possible to determine these acquisition parameters based on limited a priori knowledge of the subsurface? How should the geometry of the acquisition change when considering ray-based traveltime tomography (TT) versus wave-based FWI? In what scenarios might a sparser 3D OBS deployment be preferable to a densely sampled 2D profile? What shot/receiver configuration would be most effective?

Conversely, we can consider optimizing OBS acquisition at the data processing stage. Here, the objective is to fine-tune the processing approach so that it makes the best use of the existing dataset to reconstruct the target within the available computational resources. Therefore, is it possible to design a data-selection or data-weighting approach that achieves optimal or uniform subsurface sampling for a given processing method? How would this optimal sampling differ between ray-based and wave-based techniques? Moreover, could the dataset be “sparsified” to optimize subsurface sampling while minimizing the computational load of large-scale regional models? How much could compressive sensing and advanced regularization techniques help reduce the data volume that needs to be processed?

Answering these questions and finding associated solutions are the primary scientific goals of this project. We live in an era where enormous amounts of data are collected on nearly every aspect of life, including geophysical investigations of our planet. As the volume of data grows, it is critical that we learn to optimize both the collection and utilization of data to maximize its value for the advanced processing tools at our disposal. Only by doing so can we find a balance between the potential of advanced processing techniques and academic OBS data acquisition strategies that fully exploit this potential.

Project 3

Assessment of the reliability of earthquake preparation process indicators in a controlled seismicity model environment: from physical controls to pattern recognition

Supervisor: prof. dr hab. inż. Beata Orlecka-Sikora,orlecka@igf.edu.pl , Department of Seismology

 

REQUIREMENTS:

  • Master’s degree in geophysics, applied mathematics, physics, or a related field; demonstrated skills in numerical modelling, statistical analysis and programming (e.g., Python, R, or MATLAB, C/C++). 

TASKS DESCRIPTION:

  • Critical review of seismicity model classes with respect to their ability to reproduce progressive shear zone localization (e.g., ETAS and alternatives); implementation and calibration of selected models (e.g., statistical, rate-and-state based, and potentially custom hybrid models) in a numerical environment. 
  • Systematic generation of synthetic seismic catalogues under diverse model parameter scenarios; evaluation of earthquake preparation process (EPP) indicator behaviour, in particular SSD and dc, on synthetic catalogues and identification of conditions under which SSD–dc trajectories are consistent with real observations. 
  • Statistical testing (Monte Carlo simulations, resampling methods) to assess the significance and reproducibility of observed EPP patterns and to separate signal from random variability. 
  • Validation of EPP indicators on selected real seismicity cases under diverse seismotectonic conditions, with particular attention to the role of normal stress and pore pressure as factors modulating SSD–dc trajectories. 
  • Design of a synthetic space for machine learning: selection and characterisation of synthetic catalogues with respect to the representativeness of seismotectonic conditions and coverage of the EPP parameter space, in collaboration with the team developing AI models within the TrackPreQuake project. 
  • Collaboration with the project team on method development, interpretation of results, and preparation of scientific publications. 

Summary of the doctoral project::

The doctoral thesis focuses on the assessment of earthquake preparation process (EPP) indicators — seismic strain dynamics (SSD), a measure of the mean rate of inelastic deformation, and the seismic regularity coefficient (dc), a measure of the standard deviation of the spatial inelastic strain rate — using synthetic seismicity catalogues as a controlled testing environment. The research begins with testing the classical epidemic-type aftershock sequence model (ETAS) and demonstrating its limitations in reproducing progressive shear zone localization expressed in the SSD–dc space. The candidate will systematically extend the simulation environment with alternative seismicity models, including rate-and-state based models and potentially custom hybrid models, evaluating their ability to faithfully reproduce the characteristic SSD–dc trajectory observed prior to significant seismic events. Particular attention will be paid to seismotectonic conditions — the role of normal stress and pore pressure — as factors modulating the shape of this trajectory, which will be verified on selected real cases of anthropogenic seismicity. Validated seismicity models will be used to construct a synthetic space for machine learning models developed within the TrackPreQuake project. The work constitutes a significant contribution to the development of reliable, AI-based tools for the identification of strain localization patterns and seismic hazard assessment.
