Related Slideshow: Natural Disasters: RI’s Most At Risk and Vulnerable Communities
The below slides show what communities are at greatest risk and most vulnerable to a particular natural disaster, such as another hurricane, or a less-common disaster, such as an earthquake or a tornado. Higher scores correspond to a higher risk and vulnerability for that community. Cities and towns are listed starting with those that have the least risk and vulnerability, ending with the most at-risk and most vulnerable. Because flooding is a particular concern to Rhode Islanders, additional information on the threat of flooding from a major 100-year storm is shown.
Scoring method
The score for each type of hazard was determined by multiplying two separate scores together: the hazard risk score and the vulnerability score. The hazard risk score was calculated by multiplying three scores together: the score for frequency (how often something happens), the score for area impact (area that would be affected), and the score for intensity (such as the depth of a flood or the wind speed of a three-second gust in a hurricane). Higher scores mean a higher risk. The vulnerability score was derived using a similar multi-layered calculation that takes into account the population size and characteristics (for example, elderly and low-income populations are more vulnerable), the economy, the environment, and the number and importance of critical facilities like hospitals or power stations. Higher scores mean a greater vulnerability.
The scores are not against any scale. Instead they are relative in nature, showing how risk and vulnerability for a natural disaster is distributed throughout the state. A community with a higher score has a greater share of risk and vulnerability than one with a lower score. Scores and method information are from 2011 State Hazard Mitigation Plan. (A 2014 updated plan has been recently released, but numerical scores are not provided for each community.) For a detailed description of the entire scoring method, see PDF pages 123 to 145 on the 2011 plan.
