Overview of HAZUS for Earthquake Loss Estimation

1. Overview of HAZUS for Earthquake Loss Estimation October 28, 2011

2. What is HAZUS? • Risk assessment tool for analyzing potential losses from hurricane, flood, and earthquake • Uses current scientific and engineering concepts in a GIS to estimate hazard related damages • HAZUS is only an estimation tool for losses due to a disaster and could be significantly different from an actual event

3. Loss Estimate Process Produce maps, tables, reports Analyze social and economic impacts Consider what is at risk Identify hazard Identify physical

4. How does HAZUS calculate damages? • Damage in HAZUS is described by five damage states: • HAZUS uses damage states to estimate life-safety consequences of building damage, expected monetary losses due to building damage, expected monetary losses due to business disruption, and other social and economic impacts.

5. How does HAZUS calculate damages? (Con’t) • Damage states and engineering calculations were used to develop fragility curves for each building type • Fragility curves describes the probability of being in a specific damage state as a function of the size of an earthquake • For structural damage a fragility curve expresses damage as a function of building displacement

6. HAZUS Modules • Six Major HAZUS Modules • Inventory • PESH • Physical • Induced Damage • Socio-Economic • Long Term

7. HAZUS Inventory Module • Aggregate Information • General Building Stock • Demographics • Site-specific Information • Essential Facilities • High Potential Loss Facilities • User Defined Structures • Hazardous Sites • Transportation Lifelines • Utility Systems

8. Potential Earth Science Hazard (PSEH) • Ground Motion • Location-specific shaking • Attenuation functions • Ground Failure • Liquefaction • Landslide • Surface Fault Rupture

9. HAZUS Losses • HAZUS calculates • Losses to buildings and their content and inventory (businesses) value • Debris generation from building damages • Displaced population (used to identify evacuation routes and shelter requirements • Damage to essential facilities (police, fire, medical, schools, and EOC’s) • Damage to transportation systems (highways, bridges, ports, ferry facilities etc.) • Damage to Utility systems (potable water, oil, natural gas etc. ) • High potential loss facilities (dams, levees, nuclear power plants etc. ) • Casualties (by time of day)

10. HAZUS Analysis Levels

11. Where do I find data for use in HAZUS? • Local parcel/assessors data can be input into HAZUS. The following data is required for each parcel: • Building replacement value (typically use building improvement value). *Assessed values should not be used. • Building square footage • Building type (residential, commercial, industrial etc. ) • Building count (per parcel) • Can also update bridge, road, utility information • Shake Maps are available at USGS • http://earthquake.usgs.gov/earthquakes/shakemap/ • Choose a geographic area> Click Archive • Choose the appropriate network (Pacific NW)> Choose All Years> and choose Scenarios for Type • Once a Shakemap is selected choose Downloads. Download the HAZUS Zip File and the Shape Files.

12. HAZUS Earthquake Utilities and Procedure Documents • Shakemap Utility – Converts the downloaded shapefiles to a geodatabase (provided as a download) • Procedure for Importing Shakemaps into HAZUS (provided as a download) • SOP for Creation of Earthquake Scenario Priority Maps (contact Kelly Stone) • Earthquake Export tool – Allows the user to generate maps and tables automatically from HAZUS (contact Kelly Stone)

13. How Do I Run HAZUS? • A study region is created first in HAZUS which can be at a state, county, city, census tract, census block level • HAZUS Earthquake determines losses at a census tract level • A building specific analysis can be run in HAZUS, but requires additional building data structural engineering information • Shakemap, liquefaction, and soils can be input into HAZUS. Or an historic or arbitrary event can be ran. • Analysis is run for various building types, transportation, utilities, debris generation, displaced population etc. • Extract output and display data using ArcGIS

14. HAZUS Outputs

15. HAZUS Outputs

18. How to Use HAZUS Output • Disaster Response • HAZUS Earthquake events can be pre-run for use during disaster response • Pre-run earthquake events allow emergency management to stage resources where the highest damaged is modeled to occur • Shakemaps will be generated after an event. The post event Shakemap can be run in HAZUS providing more realistic damages during an event

19. How to Use HAZUS Output (Con’t) • Hazard Mitigation Planning • HAZUS output can be incorporated into a Hazard Mitigation Plan • HAZUS can identify hazard mitigation strategies *Tables were take from the Snohomish County Hazard Mitigation Plan located at http://www1.co.snohomish.wa.us/Departments/Emergency_Management/Information/Plans_Reports/

20. How to Use HAZUS Output (Con’t) • Community Planning • Future Development • Preparedness • Exercises • Validation Studies
