FDHI Models and their Implementation: Online Workshop Series, December 2, 4, and 6, 2024

The University of California and its partners are holding an online workshop series to present new Fault Displacement Models developed through the Fault Displacement Hazard Initiative (FDHI) Project. Participation is free, but REGISTRATION is required.

Overview of New Fault Displacement Models, November 10 2022

We are planning a half-day virtual workshop to present the work to-date of the Fault Displacement Hazard Initiative project. The workshop will discuss the new fault displacement and rupture database and new predictive displacement models developed through the project. The focus will be on the model development, model performance, and end-user information for implementing the models. Participation is free, but registration is required.

SCEC Virtual Workshop: Standardizing Post-Earthquake Field Data Collection, January 2022

We convened a two-day virtual workshop on coordinating post-earthquake data collection. The presentations and discussions were focused on four key aspects of scientific earthquake response: coordination, communication, data needs, and data collection. Our goal for this workshop was to begin working towards updating and improving post-earthquake scientific response, with a focus on meeting the needs of a range of data users. The key outcome of this workshop is a set of action items identified by the workshop attendees, which exceeded 150 people from across the globe. The SCEC Project Report is here.

SCEC Workshop: Next-Generation Fault Displacement Hazard Models, October 2019

We convened a one-day workshop to assemble an interdisciplinary group of researchers actively contributing datasets, analytical methods, models, and simulations pertaining to surface fault displacements, with emphasis on collecting and incorporating measurements of permanent off-fault deformation in Probabilistic Fault Displacement Hazard Analysis (PFDHA). The workshop provided a structured forum to help initiate interdisciplinary collaboration for collecting, analyzing, and modeling data bearing on total (on-fault and off-fault) coseismic displacements. It was also an opportunity for researchers assembling fault displacement databases to present interim results, distribute preliminary database versions to community analysts, and improve future database versions via collaborative efforts to establish dataset needs and reporting conventions for on-fault and off-fault deformation measurements. The SCEC Project Report is here.


Presentations

We submitted a conference paper and presented a poster for one of the new fault displacement models at the 12th National Conference on Earthquake Engineering in Salt Lake City. See our poster here.

A Technical Session on “Distributed Deformation from Surface Fault Rupture” at the 2022 Seismological Society of America Annual Meeting in Bellevue was convened by FDHI project collaborators. Check back soon for a link.

Several FDHI project collaborators presented at the 2021 Seismological Society of America Annual Meeting. See the Special Sessions for “Fault Displacement Hazard” here.

We presented a poster at the 2019 Seismological Society of America Annual Meeting in Seattle on our new database. Read the submitted abstract here and see our poster here.


International Collaboration

We are excited to be collaborating with researchers from INQUA-TERPRO-IGF on their global fault displacements project (“SURE”). Stay up-to-date on their progress here.
