Green Foundation Postdoctoral Appointments in Geophysics at Scripps Oceanography
|
|
The Institute of Geophysics and Planetary Physics (IGPP) at Scripps Institution of Oceanography, University of California San Diego, has openings starting in 2026 for up to two postdoctoral Green Scholars and one Miles Postdoctoral Fellow.
|
Green Scholar positions are 50% supported by funding from the Green Foundation for Earth Sciences, matched with extramural funds for specific research projects. Miles Fellow positions are 100% supported by the Green Foundation for Earth Sciences.
|
Before submitting an application, applicants should contact potential IGPP mentors to find out if they have a suitable project. Green scholars are encouraged to broaden their experience through interaction with other researchers at IGPP; individual research goals may be pursued if project progress can be maintained. Information on recent IGPP research is available at https://igpp.ucsd.edu/about.
|
The positions are for one year, renewable for a second year subject to satisfactory performance and availability of funds. Starting salary is $75,000/yr plus benefits, along with $3,000/yr of discretionary research funds.
|
Please address questions to greenfound@ucsd.edu.

PhD Opportunity in Earthquake Seismology at the AI/ML Frontier
|
Earthquake Seismology Group at the University of California, Riverside, led by Prof. Abhijit Ghosh, invites applications for a funded PhD position. The successful candidate will conduct fundamental research in earthquake physics and processes via advanced AI/ML and computational methodologies.
|
Research will operate at the intersection of seismology and computational science, utilizing state-of-the-art AI/ML models as powerful analytical tools. This integration aims to reveal new understandings of fault mechanics, seismic source processes, and ultimately, advance hazard mitigation, addressing complex geophysical problems inaccessible by traditional methods. Access to robust computational infrastructure, including State-of-the-Art High-Performance Computing (HPC) Clusters will be provided.
|
We seek applicants with a strong analytical and quantitative background, preferably encompassing one or more relevant fields including Seismology, Geosciences, Geophysics, Mathematics, Physics, or Computer Science/Engineering. Prior experience in earthquake seismology and/or AI/ML is beneficial, but not required.
|
|
For more information, please contact Abhijit Ghosh at aghosh@ucr.edu.
|
For full consideration for all university fellowships, complete your application by Nov 30, 2025.

Call for Paper "State-of-the-Art Information Science in Earthquake Research: Developments and Applications" in Earth, Planets and Space (EPS)
|
We are happy to announce the launch of Collection in Earth, Planets and Space (EPS) titled "State-of-the-Art Information Science in Earthquake Research: Developments and Applications."
|
This Collection (something like Special Issue) focuses especially on developments and applications of state-of-the-art information science, including AI, machine learning, and statistics, beneficial to earthquake research. Potential targets are, for example,
|
- AI techniques for detection of seismic signals in continuous seismic or GNSS waveforms with determining their features,
- AI techniques that can be replaced with massive simulations and modeling in earthquake science,
- usage of generative AIs in earthquake research,
- cutting-edge Bayesian statistical methods, such as data assimilation, in earthquake research,
- developments and applications of modern methods in statistical seismology, and
- other related topics related to integration of information and earthquake sciences.
Lead Guest Editor is Hiromichi Nagao (ERI, Univ. Tokyo).
Guest Editors are Toshitaka Baba (Tokushima Univ.), Ying Chen (National Univ. Singapore), Masayuki Kano (DPRI, Kyoto Univ.), Hisahiko Kubo (NIED), Zachary Ross (Caltech), Takahiko Uchide (GSJ/AIST), and Jiancang Zhuang (ISM). Please feel free to contact us.
|
We look forward to your manuscript submission to this Collection in EPS.

PhD Scholarships in Ground Motion Simulation, Validation, and Applications
|
Two PhD scholarships are available for multiple topics associated with earthquake-induced ground-motion and site response prediction utilizing simulation-based methods. The overarching aim in all specific project instances is to advance understanding of ground-motion phenomena and predictive ability through hybrid broadband simulations. In some instances, this is directly through the use of simulations for seismic hazard analysis, and in other instances through the use of simulations to constrain empirical ground-motion models for parameter combinations that observational data are deficient. The projects are based at the University of Canterbury in Christchurch, New Zealand, but PhD students will also interact with national and international collaborators.
|
- Toward fully non-ergodic considerations in ground-motion simulation: Simulations have inherent event-, region- and site-specific representations that do not make the ergodic assumption conventionally employed in many empirical ground-motion models, the most obvious being a 3D velocity/crustal model. However, many parameters and sub-models within such simulations currently use coefficients that are constant over a broad geographical region, examples include Brune stress parameter, anelastic attenuation dependence on shear-wave velocity, and shallow site response dependence on 30-m-averaged shear wave velocity. This project is intended to progress toward all key model parameters and sub-models having non-constant regional variation. Attention will also be given to these model and parameters having probabilistic distributions in order to enable simulations to propagate parameter uncertainty into a probabilistic ground-motion distribution. Observational data from earthquakes in New Zealand will be used to develop regionally varying models, as well as performing validation to iteratively address trade-offs that can exist between prediction residuals and different model components. Supervisors: Brendon Bradley, University of Canterbury; Peter Stafford, Imperial College.
- Validation of 3D ground-motion simulations at high frequencies: There is increasing emphasis on pushing the upper frequency limit of 3D ground-motion above 1Hz to cover the full range of engineering interest (10+ Hz). This requires consideration of many phenomena that can be overlooked for frequencies 1Hz, including: topography, frequency-dependent Q, small-scale velocity heterogeneties, plasticity, among others. While much emphasis has been placed on the computational inclusion of such phenomena in wave propagation simulations, little to no attention has currently been given to quantifying the improvement (if any) in the prediction of the resulting simulations against observations. This includes understanding the LF-HF transition frequency which is optimum based on currently adopted rupture and velocity models, and thus where further research is principally needed in order to achieve greater improvements in the LF simulation that push the optimum to higher and higher frequencies. This research will seek to answer that question using a large database of observed crustal and subduction earthquakes in New Zealand. Supervisors: Brendon Bradley, Robin Lee, University of Canterbury.

Relevant background: Applicants should have a background in Civil Engineering, Geophysics, or related disciplines. High competency in data analysis, numerical modelling, and programming is desired.
PhD Scholarship Details: This scholarship includes a $35,000 NZD/year stipend (tax-free) and all university tuition and fees for the three-year duration of the PhD project.
Application Details: If interested in applying, please contact brendon.bradley@canterbury.ac.nz with the email title “PhD Scholarship in ground-motion simulation, validation, and applications” and attach the following documents: (1) CV; (2) cover letter; and (3) any digital copies of journal/conference papers and/or theses you have authored. Applications close 15 December 2025, but will be reviewed as they are submitted. The projects are expected to start between 1 July – 1 October 2026, though a expedited/delayed start maybe possible depending on individual circumstances.
