The November 2019 release has made significant updates to the below datasets. Essential Facility, Transportation and Utility data have been updated using the latest versions (as of November 1, 2019) of the HIFLD Open datasets. All valuations have been updated to RSMeans 2018 values and reflect Census 2010 data. Please see Release Notes for additional details.
The Hazus Tsunami model requires users to upload their own data to run the Tsunami hazard. Hazus was designed to use adapted formats based on those used by NOAA's Pacific Marine Environmental Laboratory (PMEL) and specifically their Short-term Inundation Forecast for Tsunami (SIFT) product. This folder contains sample Tsunami hazard data from PMEL SIFT for five localities: Crescent City, CA; Garibaldi, OR; Homer, AK; Kahului, HI; and Westport, WA. Each state folder contains Tsunami hazard input data required for Level 1, Level 2, and Level 3 analysis in Hazus. These files have been tested and will run in Hazus, or can be used as templates in preparing your own local Tsunami hazard data. For more information on PMEL SIFT data and the data requirements for each level of Hazus Tsunami analysis, please see the Hazus 4.0 Release Notes . Download the sample data here .

Hazus 4.2 Service Pack 02 Release
Hazus 4.2 Service Pack 1 must be installed before Service Pack 2. Service Pack 2 for Hazus 4.2 was released on February 28, 2019. Download it here .
Significant enhancements are highlighted below:
Supports both a Level 1 and Advanced User option for the treatment of soil amplification with USGS probabilistic ground motion grids
The Advanced Engineering Building Module (AEBM) processing time is substantially optimized to support large (>1,000) record sets
The automated interface with USGS ShakeMap data is extended to include available USGS ShakeMap scenario earthquake events in addition to actual events

User Data/Depth Grid quality assurance and format verification checks are provided. User tips and user-friendly messaging are provided if a depth grid fails to load
Study region aggregation times were optimized for the flood model when clipping agricultural features
Additionally, significant defect resolutions addressed include:
Failure to import depth grids no longer corrupts the study region
Facility functionality in earthquake model is corrected and provided based on a scale of 0-100% functional
Both AEBM and UDF have been optimized for probabilistic scenarios when user supplied soil maps are used
Total households without power or potable water estimates were corrected when results from more than one State are reported
A correction in the casualty code that can occasionally produce erroneously high commercial casualties was implemented
User modified and added custom depth damage functions have been validated to produce expected results
GeoProcessing (GP) option settings for the flood study region map templates were modified to address excessive map template save times after running hydrology and hydraulics
An error that resulted in reversed County names for St Croix and St Thomas in the Virgin Islands was corrected
A defect was fixed where the sum of damaged building counts pre- and post-NFIP exceeded total inventory building counts in cases of extreme flooding
The probabilistic hurricane scenario storm track is now mappable for each representative return period
County boundaries available in the Hurricane Table of Contents align with the County boundaries provided by the Hazus system files
Prevented deterministic scenario crashing while saving the storm tracks
Probabilistic hurricane wind field data for Alabama and Connecticut are now available in the Hurricane Table of Contents
Required hurricane state data files were restored in West Virginia reenabling Hazus Hurricane module loss assessment capabilities for the State

it here .
Significant enhancements are highlighted below:
Developed a new module to allow the use of user-supplied hurricane surge data for combined wind-surge loss deterministic scenarios. This allows the use of high-resolution hurricane surge products from authoritative providers or those developed using field observations during or after future landfalling hurricanes.
Updated Hurrevac and historic hurricane data with 2017 and 2018 hurricanes.
Hazus State Databases have been updated using the latest version available at the time of this release of Homeland Infrastructure Foundation-Level Data (HIFLD) Open Essential Facility (https://hifld-geoplatform.opendata.arcgis.com/ ) datasets for care facilities, emergency operation centers, police stations, fire stations, and schools.
Provided enhancements for handling of ShakeMap grid parameters. This includes the handling of special characters, error checking, and the creation of a new study region table to preserve the ShakeMap event parameters.
Existing Hazus damage state descriptions for the Hurricane and Earthquake Quick Assessment Summary (QAS) reporting were updated using the FEMA Individual Assistance (IA) Preliminary Damage Assessment (PDA) categories.
Additionally, significant defect resolutions addressed include:
Corrected an issue to ensure that user changes to the Tsunami Model evacuation walking speed reduction factors were being correctly applied.
Corrected highway bridge depth damage function loss computation to align with highway bridge return period damage functions.
Corrected rental and relocation cost calculations in the Earthquake AEBM Module.
An issue where ground motions outside ShakeMap grids were NULL and losses exaggerated, as well as an issue causing the earthquake analysis to crash with multi-line segments were fixed.
Hurricane specific State boundaries were updated to align with system County and State boundaries for all hazards to ensure agreement for thematic mapping.
