Lifeline Infrastructure System Resilience Presentation

Lifeline System Resilience Presentation Abstract

Lifeline infrastructure system resilience prior to and following disruptions due to natural or technological hazards is intimately linked to and supports community resilience. Lifelines are interdependent socio-technical systems vital in the day-to-day operations of our communities, and their basic services essential for community recovery after earthquakes and other extreme events. They include electric power, gas, and liquid fuel, water and wastewater, telecommunication, and multi-modal transportation systems. This webinar identifies features making lifeline systems resilient. Functionality and operability are continuous expressions useful for measuring lifeline system resilience. These expressions are explored along with the basic lifeline services and their recoveries needed to ensure communities can achieve their resilience objectives. The concept of functional recovery is being further developed by FEMA and NIST as part of the 2018 National Earthquake Hazards Reduction Program (NEHRP) reauthorization and is closely related to operability. Attendees will gain an understanding of…
