Deformation Models for the U.S. National Seismic Hazard Model
Seismological Research Letters (SRL) is soliciting papers for a Focus Section on Deformation Models for the U.S. National Seismic Hazard Model.
An update to the National Seismic Hazard Model (NSHM) will be published in 2023, covering the conterminous U.S., Alaska and Hawaii. This affords an opportunity to revise several components in its construction, including the earthquake rate model (ERM), which characterizes the earthquake sizes, spatial distribution, and frequencies of occurrence through probabilistic seismic hazard analysis (PSHA). A key ingredient of the ERM is a collection of fault slip rates on active faults and `off-fault’ deformation rates and their uncertainties. These rates have been traditionally estimated using geologic fault slip rates, but slip rates derived from geodetically-measured interseismic crustal motions were first introduced in 2014 into the U.S. NSHM. The existence of well-vetted geodetic datasets of interseismic deformation and derived products, as well as the maturing of several interpretational models over the past decade, prompts a renewed effort to incorporate geodesy into the U.S. NSHM.
We invite papers that describe ongoing efforts to provide deformation models for use in PSHA, with applications to the current update of the U.S. NSHM. This may include relevant geological and geophysical data sets, quantitative interpretational methods of these data, construction of satellite models, e.g., of fault creep or locking depth, and the utility of estimated deformation rates and uncertainties for the ERM. We also welcome contributions on the use of deformation models as part of non-U.S. national seismic hazard models, or that describe integrative approaches to PSHA that combine deformation data with other geological or geophysical data.

Deadline for submission of manuscripts: 2 May 2022
Articles accepted to the SRL Focus Section on Deformation Models for the U.S. National Seismic Hazard Model will be published online soon after acceptance and collectively in print in the November 2022 issue.
Papers will be reviewed as they are received and published online prior to the print issue. In preparing manuscripts, authors must follow the SRL author guidelines at www.seismosoc.org/publications/srl-authorsinfo/. Papers must be submitted via the SRL online submission system (www.edmgr.com/srl) under the category “Deformation Models for the U.S. National Seismic Hazard Model.”
