Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Three Announcements from the SCEC Community

Date: 04/05/2024

Dear SCEC Community,

See the following announcements:

  • Job Posting for CIG Postdoctoral Fellow
  • BSSA Call for Papers: Special Issue on Improving Measurements of Earthquake Source Parameters
  • 2024 Crustal Deformation Modeling Workshop

Job Posting for CIG Postdoctoral Fellow

Applications are invited for a Postdoctoral appointment at the Computational Infrastructure for Geodynamics (CIG) at the University of California Davis. The position is expected to contribute to the development and support of teaching numerical modeling in geodynamics and towards developing independent research. CIG supports the development and dissemination of software for geophysics and related fields by supporting the infrastructure for the development of open source, community codes.

The candidate is encouraged to develop innovative, original, and feasible software engineering and/or software development projects that complement and/or improve our current practices. CIG supports communities in computational science, dynamo, education, long-term tectonics, mantle convection, multiphysics, seismology, seismic cycles, and short-term crustal dynamics. Active areas of interest include:

  • the advancement of an existing non-CIG code for inclusion into the CIG community
  • significant expansion of an existing CIG code
  • the application and / or development of new tools for visualization, management, and analysis of model data, and
  • outreach and education.

The successful candidate will also contribute to the development of:

  • education teaching modules for computational geodynamics employing best practices in teaching and software development
  • computational workflows in their area of expertise

The successful applicants are expected to collaborate with the relevant members of CIG headquarters, the CIG community, and relevant outside communities.

These positions are expected to participate in ongoing CIG Headquarters’ activities including maintaining the community software infrastructure and participating in outreach including leading tutorials.

BSSA Call for Papers: Special Issue on Improving Measurements of Earthquake Source Parameters

Deadline for Submission: 15 June 2024

The Bulletin of the Seismological Society of America (BSSA) is soliciting papers for a Special Issue on Improving Measurements of Earthquake Source Parameters. Earthquake source parameters such as magnitude, seismic moment, source dimension, stress drop, and radiated energy are fundamental to understanding earthquake physics, and also key ingredients in earthquake ground motion modeling, rupture simulation and statistical seismology. However, the uncertainties in these parameters estimated from the radiated seismic wavefield are large due to variability in approaches, including site and attenuation characterization, and estimates for an individual earthquake made by different studies can vary greatly. The international SCEC/USGS Community Stress Drop Validation Study was designed to distinguish between estimates of source parameter variation resulting from real physical controls and from methodological artifacts, by inviting researchers to use a common dataset to independently estimate comparable measurements using a variety of methods.

BSSA welcomes contributions to the Special Issue that focus on source parameter estimation, including methods, uncertainties, and underlying physical mechanisms. In addition to work that is part of the ongoing community study, we solicit papers on methodological improvements to spectral and time-domain methods and novel approaches to infer source parameters including, but not limited to, seismic moments, source dimension and stress drop, directivity and finite-fault models. Collaborative comparisons of multiple techniques are especially encouraged.

Deadline for Submission: 15 June 2024

Articles accepted to this BSSA Special Issue will be published online soon after acceptance and collectively in print in the February 2025 issue. Papers will be reviewed as they are received and published online prior to the print issue.

Papers must be submitted via the BSSA online submission system (www.edmgr.com/bssa) under the category “Improving Measurements of Earthquake Source Parameters.”

2024 Crustal Deformation Modeling Workshop

June 10-14, 2024, Colorado School of Mines, Golden, CO
The focus of this gathering will be computational models addressing crustal deformation in the following areas:

  •   Constraining long-term fault slip rates and their uncertainties using geodetic and geologic data;
  •   Earthquake cycle modeling with a focus on constraining models using seismic and geodetic data;
  •   Interaction of fluids and faulting; and
  •   Separating contributions of surface loading and tectonic loading in crustal deformation.

The workshop will be held June 10-14, 2024, in Golden, Colorado on the campus of the Colorado School of Mines. The first two days of the workshop will be tutorials related to PyLith (an open-source, community code for modeling crustal deformation with a focus on earthquake faulting; all software tools used in the tutorials is free and open-source) followed by three days of science talks, discussions, and informal tutorials and collaboration.
We will provide reimbursement for a portion of the travel costs incurred for registered attendees with official appointments at U.S. institutions. To attend the workshop, please read through all event details and then use the "applying via eventbright" link on the workshop webpage.
