The USGS periodically updates its National Seismic Hazard Models (NSHMs) for the United States and its territories. For each NSHM update, the USGS requests that the seismic hazard community bring to our attention new earthquake source and ground motion data or models that could be included. The deadlines for these community contributions, and the schedule for each NSHM update (including public workshops), are given below.
Tabulated below are the deadlines for community contributions for the NSHMs:
Region | Publication Date | Community Contributions Deadline |
|---|---|---|
50-State | 2029 | Dec. 31, 2026 + 1-month extension |
GNMI & AmSam | 2027 | Jun. 30, 2024 |
PRVI | 2025 | Dec. 31, 2022 |
50-State | 2023 | Dec. 31, 2020 |
Only published (or accepted for publication), peer-reviewed data and models will be considered. The sooner they are brought to our attention, the more likely it is we can include them in the updated NSHMs, resources permitting.
Please bring the publications to our attention by emailing nshmp-support@usgs.gov. Someone will reply to confirm receipt and request additional information, if needed.
