National Seismic Hazard Model Project Steering Committee

Science Center Objects

The National Seismic Hazard Model Project (NSHMP) Steering Committee is a panel of nine subject matter experts that meets routinely with the NSHMP to discuss and review inputs to the National Seismic Hazard Models (NSHMs).

The National Seismic Hazard Model Project (NSHMP) Steering Committee is a subcommittee of the Scientific Earthquake Studies Advisory Committee (SESAC) of the U.S. Geological Survey. The NSHMP Steering Committee was established to critique and review updates of the National Seismic Hazard Models (NSHMs) and to provide overall guidance on the efforts of the NSHMP.

The committee consists of nine subject matter experts from academia and industry. The NSHMP Project Chief selects the committee members, with input from the Earthquake Hazards Program (EHP) Coordinator. The members are selected based on their subject matter expertise, with each member representing a unique and critical component to the NSHMs. The 2020 membership is listed below:

NSHMP Steering Committee
Area of Expertise Member (Affiliation)
Representative science expert on the Central and Eastern United States (CEUS) Heather DeShon (Southern Methodist University)
Representative science expert on the Intermountain West (IMW) John Anderson (Chair) (University of Nevada, Reno)
Representative science expert on the Pacific Northwest (PNW) Ray Weldon (University of Oregon)
Representative science expert on California Tom Jordan (University of Southern California)
Representative science expert on ground motions in the CEUS Gail Atkinson (Western University)
Representative science expert on ground motions in the Western United States (WUS) Ken Campbell (CoreLogic, Inc.)
Representative engineering expert from industry Nilesh Shome (Risk Management Solutions)
Member At Large Jack Baker (Stanford University)
Member At Large (Building Code expert) Jon Stewart (University of California, Los Angeles)

SESAC appoints one of the members as the Chair of the Steering Committee, with advice from the Project Chief of the NSHMP. Each member of the Steering Committee is appointed for a 3-year term, and appointments are renewable, as needed. The Steering Committee recommends that there be regular rotations of members to allow for new scientific expertise on the committee. Coordinators (or their representatives) from the EHP, as well as representatives of other agencies in the National Earthquake Hazards Reduction Program (NEHRP) (i.e., FEMA, NSF, and NIST) are ex officio members of the Steering Committee, and are therefore invited and welcomed to join meetings.

The NSHMP Steering Committee generally meets in person one or two times per year, but they also meet in several web conferences throughout the year to discuss specific topics of importance to the NSHMP. Years when a NSHM is close to being finalized and released tend to require more meetings than other years. The Steering Committee is routinely updated on the status of the NSHMs and the science and models being incorporated into the resulting hazard maps. The NSHMP relies on the scientific expertise of the Steering Committee members to review the models and offer guidance to the NSHMP. The Steering Committee is also invited to attend all NSHMP public workshops, where the NSHMP presents draft NSHMs to the public for input and review, as well as participate in the public review period when the draft NSHMs are made publicly available online. The Steering Committee also provides input to the NSHMP and to SESAC about project and research priorities.
