“…However, most studies do not account for temporal changes in risk perception. Although some studies examine risk perception shortly after a disaster [60][61][62] or changes in risk perception in communities where hazards have occurred previously [23,25], research is limited to comparing pre-disaster risk perceptions to risk perceptions measured within a short period after a disaster.…”

Risk reduction behaviors are often voluntary and influenced by how at-risk an individual personally feels, known as risk perception. This paper examines how risk perception changed from before and six months after Hurricane Irma, a Category 3 storm that narrowly missed Sarasota County, FL. Both surveys asked about residents’ hurricane risk perceptions, evacuation behaviors, mitigation plans, and attitudes about self-efficacy. For each question found in both surveys, the research used t-tests (ɑ = 0.05) to assess whether significant changes in risk perceptions occurred between responses. The results suggest that Hurricane Irma had a notable impact on risk perception. The changes were most evident in reported levels of self-efficacy as residents were less likely to feel able to sufficiently prepare for or recover from hurricane impacts after Hurricane Irma. Respondents were also more likely to believe individuals are responsible for preparing for hurricane impacts. The findings have implications for public risk communicators, who may find it effective and sustainable to appeal to residents’ lowered self-efficacy or sense of responsibility for the dangers of hurricanes while implementing policies and communication strategies.

Hurricane Ike, which struck the United States in September 2008, was the ninth most expensive hurricane in terms of damages. It caused nearly USD 30 billion in damage after making landfall on the Bolivar Peninsula, Texas. We used the Delft3d-FM/SWAN hydrodynamic and spectral wave model to simulate the storm surge inundation around Galveston Bay during Hurricane Ike. Damage curves were established through the relationship between eight hydrodynamic parameters (water depth, flow velocity, unit discharge, flow momentum flux, significant wave height, wave energy flux, total water depth (flow depth plus wave height), and total (flow plus wave) force) simulated by the model and National Flood Insurance Program (NFIP) insurance damage data. The NFIP insurance database contains a large amount of building damage data, building stories, and elevation, as well as other information from the Ike event. We found that the damage curves are sensitive to the model grid resolution, building elevation, and the number of stories. We also found that the resulting damage functions are steeper than those developed for residential structures in many other locations.
