NOTE: A new version of the HERA tool is currently in development and will be posted soon. Please contact Ferdouz Cochran at if you have any questions in the meantime. Thank you for your patience!


HERA is a decision-support tool designed to assist community agencies in planning and preparedness for extreme events.  The tool provides decision support through:

  • Data visualization
  • Providing county-level data and information on extreme events
  • Probabilities and recurrence intervals for extreme events
  • Comparisons across counties
  • Information on event-specific impacts
