The USGS is hosting a user-needs workshop for the upcoming 2023 National Seismic Hazard Model (NSHM). Unlike previous NSHM user-needs workshops, this one will primarily focus on needs that affect/change the scientific development of the NSHM. For example, user needs for longer-period ground motions have led to incorporation of basin effects in the NSHM.

The workshop will be held remotely June 28, 29, and 30 from 1 to 2:30pm Mountain Daylight Time (MDT)


In lieu of RSVPs for the workshop, we're asking interested parties to sign up for our NSHM email list (i.e., if you've already received an email directly from the NSHM list, then you're already signed up). All information about the workshops (including other upcoming workshops), will be sent through the email list -- including the MS Teams links needed to participate. To sign up for the email list, visit: https://listserv.usgs.gov/mailman/listinfo/nshmp_workshops

Questions: contact Ben Mason (mailto:hmason@contractor.usgs.gov) or Nico Luco (mailto:nluco@usgs.gov)
