Hazardous Extremes for Risk Assessment Tool


About HERA

Welcome to the Hazardous Extremes for Risk Assessments (HERA) tool. HERA is a geospatial tool designed to assist local and regional decision-makers to assess and plan for meteorological and climatological hazards in their area. The tool provides decision support through:

  • Hazard data visualization in county maps and annual tables
  • County-level counts and probabilities of hazardous and extreme events
  • Comparisons across counties
The tool uses historical data to provide information by county in the southeastern states. The original version of HERA based on Tableau can be found here.

To navigate through HERA, select State, Hazard and Subcategories from the drop-down menu, and adjust the years of interest via the time slider. To view a Count of the number of hazard events that have occurred and the Probability that at least one event of that hazard will happen in a year, click on a county on the map. The default Count and Probability are calculated for all years, but will change if the user changes the range of years on the sliding time bar. All information on a page can be displayed for a particular county by clicking on a single county, or select multiple counties by holding down the Shift key.

HERA is a CISA-SERCC collaboration and a team effort led by Chip Konrad. Other team members include Ferdouz Cochran, Amanda Farris, Yates McConnell, Montana Eck, Sandra Rayne, William Schmitz, Hunter Spitzer, Bryttani Wooten, and July Yang.
