Assessment of Protective Actions and Adjustments Taken by Shelter-in-Place Households Facing Disruptions in Critical Lifeline Services
Publication: Lifelines 2022
ABSTRACT
The research explores a dimension of preparedness against natural hazards by investigating disaster-induced service disruptions of critical lifelines. By using empirical survey data for regression modeling, the research establishes a methodological framework for examining protective actions and adjustments to service disruptions. Respondents were shelter-in-place households impacted by the power, water, and health facility disruptions caused by Hurricane Florence or Hurricane Michael in 2018. The study analyzes influencing factors such as sociodemographic characteristics, previous experience and expectation of service disruptions, and preparedness ability. Findings from regression models determined that number of protective actions were most influenced by expectation of power disruption, greater days of preparedness, and greater perception of preparedness, which emphasizes the importance of communicating and educating the community about preparedness measures. Additionally, socially vulnerable populations were associated with distinct adjustments such as selecting to tolerate the power disruption as opposed to leaving the residence or using a power generator.
