Outline• Hazus
• Background• International Methodology
• Cairo Risk Assessment Study• Hazard• Inventory• Vulnerability
• Results-Demo• 1992 Earthquake Calibration• Cairo Probabilistic Losses• Alternative Futures Scenarios
Hazus Risk Assessment Tool• Earthquake, flood and
hurricane wind modules• Developed in conjunction
with the National Institute of Building Sciences
• Runs on ESRI ArcGIS 10 platform-free 60 day evaluations www.esri.com
• Largest extension of ArcGIS• Over 200 data layers – all open source
Hazus\GIS• Results identify specific and
general vulnerabilities• Visually displays impacts
to key decision makers and the public
• Calculates scientifically-defensible damages, economic losses, and mitigation benefits
• Facilitates a risk-based approach to prioritize mitigation strategies that maximizes the return on investment
Hazus is Multidisciplinary
• Subject Matter Experts/User Groups• GIS experience• Engineering expertise• Hazard information (seismologist, geologist,
meteorologists) • Social scientist (housing)• Emergency management community• Decision/policy makers
Brief History• Project started back in 1992• Replace “black box”• Provide national capabilities• Earthquake model functional
since 1997• 1,000’s of HAZUS users
• Local, State, & Federal Agencies• Private Sector• Universities

International Applications: GIS based method for exporting the Hazus
Earthquake Model for Global Applications
Concept
• Utilize Hazus earthquake model outside the U.S. • Start with a Proxy Building Stock and replace
with local information.• Focus limited resources towards developing
inventories, engineering parameters and hazard data rather than new software.
• Prevents duplication of effort
Developing International Building Inventories
• EERI’s World Housing Encyclopedia http://www.world-housing.net/
• Hazus Advanced Engineering Building Module (AEBM), included with program
• Hazus New Building Type Wizard, included with program
• Hazus Comprehensive Data Management System (CDMS), lap top based data collection interface
• ROVER (Rapid Observation of Vulnerability and Estimation of Risk) data collection tool
Integration of Data Sources• LANDSCAN 2012 Global Population
Database for Egypt• 1 km grids (10 km and 100 km where pop
<1,000)• Oak Ridge National Labs
http://www.ornl.gov/landscan/• Demographics: Age and Male/Female provided
by City of Cairo
Part 1 of 3: Inventory•In general, earthquake results are sensitive to four categories of inventory parameters (among others)
• Location (longitude & latitude, whether site-specific or census-tract (grid) based)
• Classification with respect to earthquake vulnerability (facility type, capacity, building type & other construction characteristics) that affect seismic performance
• Valuation (cost of repair and replacement, business parameters)
• Societal (number of occupants)
NRIAG Inventory: City of Cairo Parcel DataIncludes:
• Construction Type• Condition• Number of Stories• Year Built
Limitations: • Building Area Estimated from Lot Area and Zoning
Density• Building Value Estimated from Default Replacement• Building Counts = Parcel Counts (1 per Parcel)

“Construction Type”• Seismic Code adoption history compared to year
built, construction type and condition
• Limitations:• Assumes enforcement• Condition not the same as material quality
Seismic Code History in Egypt• 1989-first code to consider seismic loading, crude
percentage• 1993-after 1992 event, offered more building specific
design levels• 2004-enhancements, follows UBC 1997 framework• Egyptian code practice (ECP-201) • ECP (1993) ECP (2008)
• Pre-Code < 1993 (no code)• Low Code 1993-2004 (UBC, Zone 1-2)• Moderate Code >2004 (UBC, Zone 3), Quality 1

Casualty Parameter Modifications-Collapse Rates for Completely Damaged Structures
• Collapse rates for complete damage state—drives much of the fatalities and severe injuries.
• U.S. collapse rates are between 3 and 15% for completely damaged structures.
