StEER Event Responses

The StEER event responses cataloged in the image galleries below may include one or both of the following: 

VASTs focus on compiling relevant information from public sources and social media immediately after the event, complementing efforts underway by other organizations such as the Earthquake Engineering Research Institute (EERI) Virtual Earthquake Reconnaissance Teams (VERTs). This results in a Preliminary Virtual Reconnaissance Report (PVRR) that is released within a few days of the event and before Field Assessment Structural Teams deploy.

Virtual Assessment Structural Team (VAST)

If the PVRR indicates the event will contribute new knowledge on the performance of the built environment under this hazard, StEER will assemble one or more FASTs. The first FAST (FAST-1) generally leverages regional experts to enter the affected region as swiftly as possible. FASTs will engage a variety of assessment technologies, including Unmanned Aerial Vehicles (UAVs), mobile applications for Door-to-Door (D2D) Damage Assessments, LiDAR imaging technologies, and Vehicle-mounted Applied Streetview (ASV) cameras. The collected data is rapidly analyzed to author an Early Access Reconnaissance Report (EARR), released within a few days of FAST-1's mission, to inform the responses of subsequent reconnaissance teams.  FAST data is then processed through StEER's quality assurance protocol and prepared for long-term curation.

All StEER reports and data are curated on NHERI Design Safe. A list of these is available on the StEER Products page. Additionally, all D2D assessment data is available in near-real-time through StEER's Fulcrum Community site. The interactive map above displays the current catalog of D2D assessment data collected by StEER since 2018. Visit StEER's Fulcrum Community site to fully access this data, as well as data collected in the 2017 Hurricane Season prior to StEER's official formation.

StEER recommends using and citing its published datasets as a matter of best practice in data re-use. However, StEER damage assessments are available in near real time, even before they complete the Data Enrichment and Quality Control Process. When such unpublished data is used in whole or part, the following citation practices are encouraged:

  1. Images from Fulcrum Community: imagery downloaded from the Fulcrum Community page can be cited as: Investigator Last, Investigator First Initial (Year) "Address Full," NSF Structural Extreme Events Reconnaissance (StEER) Network, Fulcrum Community,, Captured: Year-Month-Date (Use Fulcrum Community fields "Name of Investigator," "Date," and "Address Full" to populate all fields in yellow) 

  2. Fulcrum Community Data: Direct use of Fulcrum Data (photos and tagged fields) or its derivatives can be cited as follows: 

    • ​a) If the entire Fulcrum Community dataset  or subsets of it is downloaded for use, it can be cited as: StEER (Year) NSF Structural Extreme Events Reconnaissance (StEER) Network, Fulcrum Community,, Accessed: Month Day, Year  (Update access date and year accordingly)

    • b) If a specific Fulcrum record needs to be cited, do so as follows: Investigator Last, Investigator First Initial (Year) "Address Full," NSF Structural Extreme Events Reconnaissance (StEER) Network, Fulcrum Community,, Captured: Year-Month-Date (Use Fulcrum Community fields "Name of Investigator," "Date," and "Address Full" to populate all fields in yellow)
