BSSA Call for papers: Special Issue on Quantifying the Long-term Prehistoric Earthquake Record; Advances and Applications

The field of earthquake geology has evolved significantly over recent decades. New technologies such as lidar and other remote-sensing techniques have allowed mapping and characterization of active faults and historical surface ruptures in unprecedented detail. Improved dating and statistical modeling techniques have resulted in more precise dating and correlation of earthquakes to explore complexities such as determining multi-fault ruptures and untangling subduction and crustal fault earthquakes. On-fault studies are complemented by off-fault studies om topics such as turbidites, coastal vertical land movements, landslides, fragile geologic features and archaeoseismology. Together these all provide important constraints on identifying and characterizing active faults in both intraplate and interplate environments, earthquake occurrence statistics, physics-based fault modeling and seismic hazard analysis and physics-based fault models.

BSSA invites contributions to a special issue that reflects upon these developments, highlights current state-of-the-art studies and techniques, and considers future challenges and opportunities in the field of quantitative earthquake geology and related disciplines to understand and model the long-term earthquake record on a fault or fault system.

Topics for this call for papers include, but are not restricted to, the following topics:
  • Earthquake geology
  • Paleoseismology, including fault trenching, coastal vertical land movements, landslide, tsunami, lake studies
  • Archaeoseismology
  • Fragile geologic features
  • Modern dating techniques and modeling
  • New methods for detecting hidden fault sources
  • Applications, e.g., multidisciplinary source modeling, seismic hazard analysis, physics-based simulation modeling
Guest Editors for this Special Issue:
Deadline for Submission: 1 June 2026

Articles accepted to this BSSA Special Issue will be published online soon after acceptance and collectively in print in the June 2027 issue. Papers will be reviewed as they are received and published online prior to the print issue.

In preparing manuscripts, authors must follow the BSSA author guidelines at https://www.seismosoc.org/publications/bssa-submission-guidelines.

Papers must be submitted via the BSSA online submission system (www.editorialmanager.com/bssa) under the category “Quantifying the Long-Term Prehistoric Earthquake Record.”

Please address questions about scientific issues to the guest editors or BSSA Editor-in-Chief P. Martin Mai at bssaeditor@seismosoc.org. Submission-related questions should be addressed to the BSSA Editorial Office at bssamss@seismosoc.org.

2nd International Workshop on Swarm-like Seismicity (Les Houches, France, 1-5 June 2026)

We are pleased to announce The 2nd International Workshop on Swarm-like Seismicity to be held at Ecole de Physique des Houches, France, 1/6/2026 - 5/6/2026.

Earthquake swarms are dominantly driven by transient forcings: fluid pressurization and redistribution, aseismic slip, magma migration, slow and fast deformation transients, and injection/withdrawal of fluids in industrial operation. Seismologists and earthquake physicists still struggle to characterize and understand the mechanisms at work during such sequences. This hampers our ability to forecast accurately the subsequent spatio-temporal evolution and energy release of these sequences, which in some cases (i.e., anthropogenically stimulated swarms, and also the rare cases of swarm activity precursory to a large, destructive mainshock) is of critical importance. The scope of this workshop is to deepen our understanding of earthquake swarm physics, through observations and models.

The conference will be held at Ecole des Houches, not far from Chamonix and the Mont Blanc, in the French Alps, from the 1st to the 5th of June 2026.

Abstracts can now be submitted. Please consult the workshop website (https://swarms2.sciencesconf.org/) for further details.

User Survey - SCEDC & SCSN Data Products & Services

The SCEDC & SCSN want your opinions on our current and future data products and services!

The Southern California Seismic Network (SCSN) and Southern California Earthquake Data Center (SCEDC) have been working to modernize our systems and procedures. We’re currently looking for community feedback to help guide the future direction of our data products and services. Please complete our survey to help us better understand the needs and desires of the seismology research community. We expect it to take around 10-20 min.

The survey will be available until March 1, 2026 and is open to everyone - even if you haven't previously used our data or services.

NASA Landslide Change Characterization Experiment Science Team solicitation now open

We are happy to announce that the NASA Earth Venture Suborbital-4 (EVS-4) Landslide Change Characterization Experiment (LACCE) Science Team solicitation is now open, with proposals due April 14, 2026 and a Notice of Intent (NOI) due on February 27, 2026. The LACCE investigation aims to improve understanding of deep-seated landslides and their response to rainfall variability and glacier retreat, using high-resolution, targeted airborne synthetic aperture radar (SAR) as the primary data source, integrated with ground-based instruments, laboratory experiments, and modeling. LACCE will quantify the number, size, motion, and groundwater hydrology of active landslides and assess their sensitivity to changes in precipitation and glacier extent. We invite Science Team proposals that contribute to one or more of the LACCE research components, including airborne and ground instrumentation, landslide remote sensing, laboratory measurements, and landslide hydrology models and landslide deformation models. Proposers are strongly encouraged to read this program element in its entirety and the additional background information on the LACCE project, including details on the project requirements for measurements and models in the LACCE White Paper at:
