Performance and Future Directions of the USGS Near-real-time Earthquake-triggered Ground Failure Product

Within minutes of any major global earthquake, the U.S. Geological Survey (USGS) Ground Failure product (GFP) provides summary alert levels and spatial estimates of landslide and liquefaction hazard and population exposure. Since the GFP went live in September 2018, 187 events have had an elevated alert level (yellow, orange, or red), indicating limited to extensive hazard and exposure. These events include well-known ground-failure triggering earthquakes such as the 2023 Türkiye-Syria earthquake sequence, the 2021 Nippes, Haiti earthquake, as well as numerous other events. In many cases, the GFP proved to be valuable by estimating the potential extent of these hazards and their overlap with the local population.  In this presentation, we discuss how the product has performed since it was deployed and how it has been used for situational awareness, planning, and reconnaissance. Significant users of the GFP include scientists, the media, emergency responders, and the public. We also discuss operational considerations, such as how moving the GFP to the cloud has improved speed and reliability. We conclude with an overview of enhancements under development, such as model regionalization, road obstruction estimation, fatality estimation, ongoing hazard information, model updating, and integration into other USGS impact products, such as Prompt Assessment of Global Earthquakes for Response (PAGER) and ShakeCast.
