The Civil Air Patrol, County, military and private helicopters provide warnings to isolated areas. 18.1.10 Critical Lifeline Infrastructure Facilities A community's infrastructure provides services, utilities and linkages which allow society to function. The term"lifelines" is commonly used for this infrastructure and can be defined as systems or networks which provide for the circulation of people, goods, services and information,upon which health, safety, comfort and economic activity depends. Lifelines are the means whereby a community supports its day to day activities and include mechanisms used to respond to emergencies. During and after hazard events, the Big Island's 'lifelines' are vulnerable to disruption and/or damage. These systems are often large, complex and interdependent. Failure of one system (or part of it) causes repercussions in other systems and therefore increases a community's vulnerability further. For example, the vulnerability of the Port of Hilo, a transportation component, could affect the entire island's energy and transportation system since all propane, diesel, gasoline, and fuel oil for the island is supplied through this one location with no alternate.
