Hazus-MH Earthquake Model

• Earthquake Model Performance
• Use of Earthquake Loss Estimates
• New Features in Hazus-MH 2.1
• Hazus-MH Earthquake Model Applications

The Hazus-MH earthquake model estimates damage and loss to buildings, lifelines and essential facilities from scenario and probabilistic earthquakes, including:

• Ground shaking and ground failure
• Estimates of casualties
• Displaced households and shelter requirements
• Damage and loss of use of essential facilities
• Estimated cost of repairing damaged buildings
• Quantity of debris
• Damage to buildings
• Direct costs associated with loss of function (e.g., loss of business revenue)
  

Earthquake Model Performance

• Hazus-MH is a regional loss estimation tool. Results are most accurate when aggregated on a county or regional scale.
• Modeled results depend on accurate inventories. The more complete the inventories, the more accurate the results.
• Because of their complexity, it is more difficult to estimate losses to lifelines (utility and transportation) than buildings.

Use of Earthquake Loss Estimates

Hazus-MH displays the analysis both through GIS maps and tables. This forecasting capability enables users to carry out a wide range of analyses.

• Emergency managers can use Hazus-MH to develop scenarios to drive exercises and support emergency operations plans.
• State Hazard Mitigation Officials can use information on costs and benefits of specific mitigation measures, and to use analysis for risk assessments for State and local hazard mitigation plans. 
• Shelter managers can use estimates of displaced households and shelter requirements to scale mass care mission requirements.
• Utility company representatives can use information on the locations and duration of potential utility outages in setting restoration priorities and committing necessary personnel and other resources.

New Features in Hazus-MH 2.1

• Menu options in the user interface of the three models in Hazus-MH (Earthquake, Flood & Hurricane) have been adjusted to provide greater consistency.
• Occupancy Mapping Schemes have been updated for the Earthquake Model.
• The Earthquake Ground Motion Model has been updated to use the latest USGS Next Generation Attenuation (NGA) functions.
• The Earthquake Model now includes a feature to analyze study regions greater than the 8 GB limit of SQL Server Express.
