Infrastructure Interdependencies Research Update
Dana Brechwald, Earthquake and Hazards SpecialistLifeline Committee MeetingJanuary 31, 2013
Objectives for Our Study• Goal
– Understand performance of infrastructure systems serving airports to better understand performance of airports and to make actionable recommendations to improve airport performance
• Objectives– Identify and qualify interdependencies and vulnerabilities– Identify “choke points,” redundancies and “islands”– Determine consequences of interdependencies on restoration and
recovery– Identify and prioritize key mitigation strategies– Facilitate conversation among key stakeholders– Make specific actionable recommendations
Scope of Our Study• Systems
– Power– Water and Wastewater– Communications– Transportation (land transportation only)– Jet Fuel– Supply Chain– Employees/People– Air Traffic Control
• Size– Region – high level– Airport-specific – more detail
Case Studies
• Don’t Wing It updated + new case studies
– 1989 Loma Prieta Earthquake
– 1994 Northridge Earthquake
– 2001 Seattle Earthquake
– 2005 Hurricane Katrina
– 2010 Haiti Earthquake
– 2011 Christchurch Earthquake
– 2011 Japan
Qualitative Approaches
• Rely on empirical observation, expert interviews
• Typically use a damage scenario• Examine whole systems, not just nodes• Look at multi-sectoral societal impacts• Wide variety of outputs

Research and Background
Oakland Airport Focus Area• Exploring partnership with Adapting to Rising Tides
project (BCDC)• Looking at multiple vulnerabilities to airport and
surrounding infrastructure

Research and Background
ExerciseBay Area Microchip Manufacturing, Inc. is a locally-owned high-tech research and manufacturing company located in a possible liquefaction area in the South Bay. In a repeat 1906 earthquake (M 7.9 on the San Andreas fault, with an epicenter approximately two miles off the coast to the west of San Francisco), the site will experience violent ground shaking and possibly liquefaction. The company is housed in a typical 1990’s office park.
