This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past four decades there have been numerous studies on hurricane evacuation. Despite a voluminous collection of literature, few studies have offered insight on whether or not evacuees make evacuation plans based on hurricane characteristics; specifically storm intensity, forward speed, and forecast track direction. In this research, residents of Pensacola, Florida and surrounding areas were surveyed and interviewed to understand the decision-making of residents that occupy a hurricane prone area. A survey was created to analyze variables that influence the decisions to stay or evacuate in the event of a hurricane making landfall. Participants were shown five different hypothetical hurricane warning graphic scenarios varying in speed and intensity. Respondents were asked if they chose to evacuate, their evacuation location, and to highlight the route they would travel to get to their destination for each scenario. No specific variables impeded evacuation. Pensacola residents evacuate in response to forecast tropical cyclone path and, to a lesser extent, intensity, and this influences their evacuation route. With this information, public officials may have a better understanding of how people perceive the threat of an incoming hurricane and inform evacuees of safe, efficient routes and destinations for the public to take in the event of an approaching storm.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine evacuation decisions of residents in Pinellas County, a vulnerable area in Florida, during Hurricane Irma in 2017, and whether those decisions will impact their future decisions to evacuate. This study also examines the residents perception of storm surge flooding during a hurricane. To understand evacuation decisions and storm surge perceptions a survey was conducted on residents in vulnerable areas of Pinellas County. The survey examined multiple aspects including the role of media, relationships, and sociodemographic status on decision making. Another aspect examined if their decision to evacuate for Hurricane Irma will impact their decision for the future. Residents were also asked to rate how different aspects of the storm influenced their decision, including flooding from storm surge. It was concluded that their decision to evacuate for Hurricane Irma will significantly impact their decision to evacuate for the next hurricane, with many residents claiming they would leave their local area. Storm surge was not perceived as the greatest threat, instead wind speed and size of storm were determined to be the greater threat. Better understanding of evacuation decisions and perceptions about storm surge can be used to update emergency management preparations and planning for the next hurricane.
Download or read book Evacuate Or Not written by Adithya Raam Sankar and published by . This book was released on 2019 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent hurricanes in the Atlantic region of southern United States triggered a series of evacuation orders in the coastal cities of Florida, Texas and Georgia. While some of these were voluntary evacuations, most of them were mandatory orders that the residents had to follow. In spite of the government asking people to vacate their homes for their own safety, many did not evacuate. Various reasons motivate individuals to choose to stay or vacate. We aim to understand the factors involved in this decision-making process and model these in a partially observable Markov decision process, which predicts whether a person will evacuate or not given his or her current situation. We consider the features of the particular hurricane, the situation that the individual is experiencing, and demographic factors that influence the decision making of individuals. The model is represented as a dynamic influence diagram and evaluated on data collected through a comprehensive survey of hurricane-impacted individuals. We also propose an improvised method of k-means clustering for tweets that considers the context of the text rather than just the cosine similarity.

Book excerpt: Little attention has been given to estimating dynamic travel demand in transportation planning in the past. However, when factors influencing travel are changing significantly over time - such as with an approaching hurricane - dynamic demand and the resulting variation in traffic flow on the network become important. In this study, dynamic travel demand models for hurricane evacuation were developed with two methodologies: survival analysis and sequential choice model. Using survival analysis, the time before evacuation from a pending hurricane is modeled with those that do not evacuate considered as censored observations. A Cox proportional hazards regression model with time-dependent variables and a Piecewise Exponential model were estimated. In the sequential choice model, the decision to evacuate in the face of an oncoming hurricane is considered as a series of binary choices over time. A sequential logit model and a sequential complementary log-log model were developed. Each model is capable of predicting the probability of a household evacuating at each time period before hurricane landfall as a function of the household's socio-economic characteristics, the characteristics of the hurricane (such as distance to the storm), and policy decisions (such as the issuing of evacuation orders). Three datasets were used in this study. They were data from southwest Louisiana collected following Hurricane Andrew, data from South Carolina collected following Hurricane Floyd, and stated preference survey data collected from the New Orleans area. Based on the analysis, the sequential logit model was found to be the best alternative for modeling dynamic travel demand for hurricane evacuation. The sequential logit model produces predictions which are superior to those of the current evacuation participation rate models with response curves. Transfer of the sequential logit model estimated on the Floyd data to the Andrew data demonstrated that the sequential logit model is capable of estimating dynamic travel demand in a different environment than the one in which it was estimated with reasonable accuracy. However, more study is required on the transferability of models of this type, as well as the development of procedures that would allow the updating of transferred model parameters to better reflect local evacuation behavior.

Book excerpt: The purpose of this study was to describe the predictors of evacuation intention among coastal residents in the State of Florida and to determine if there are meaningful segments of the population who intend to evacuate when told to do so by governmental officials because of a major hurricane. In the Americas and the Caribbean, 75,000 deaths have been attributed to hurricanes in the 20th century. A well planned evacuation can reduce injury and death, yet many people do not have an evacuation plan and do not intend to evacuate when told to do so. The study used secondary data from the Harvard School of Public Health, Hurricane in High Risk Areas study, a random sample of 5,046 non-institutionalized persons age 18 and older in coastal counties of Texas, Louisiana, Mississippi, Alabama, Georgia, North Carolina, South Carolina and Florida. Surveys for the State of Florida were segregated and used in this analysis, resulting in a study sample of 1,006 surveys from 42 counties. When asked if they would evacuate in the future if told to by government officials, 59.1% of Floridians surveyed said they would leave, 35.2% said they would not leave and 5.6% said it would depend. In Florida, 65.7% of the population had been threatened or hit by a major hurricane in the last three years and 26.6% of those had left their homes because of the hurricane. Of those whose communities were threatened by a hurricane, 83.3% of the communities were damaged and 33.8% experienced major flooding associated with the hurricane. Bivariate statistics and logistic regression were used to explore the interactions of predictors and evacuation intention. The best predictor of evacuation intention was prior evacuation from a hurricane (chi-square= 45.48, p

Available in PDF, EPUB and Kindle. Book excerpt: Tropical storms and hurricanes have caused extensive casualties and damage in past decades. Recent data indicate that the annual losses from hurricanes are increasing, partly because the U.S. coastal population has increased significantly in the past 20 years. Moreover, the housing values in these areas have increased as well. Thus, population and economic growth in the vulnerable coastal areas have made hurricanes a serious problem and created the potential for a catastrophic loss of life. The existing research literature lacks a sufficient scientific understanding of hurricane information searching and dynamic protective action decision making during events in which additional information becomes available over time. The hurricane evacuation decision context is well understood; the National Hurricane Center (NHC) issues hurricane forecast advisories every 6 hours until a hurricane turns into a tropical depression. Emergency managers and residents in the risk area are most likely to make decisions on their protective actions based on these hurricane forecast advisories. Therefore, this study uses the DynaSearch program to conduct a computer-based experiment that examines hurricane information search pattern by students playing the roles of county emergency managers, their understanding of hurricane strike probabilities and their choices of protective action recommendations during four different hurricane scenarios. This study simulates the approach of a hurricane by providing experiment participants a sequence of hurricane forecast advisories and examining how they search for information, change their threat perceptions and implement protective actions over time. The results show that (1) People prefer graphic information (especially the forecast track and uncertainty cone) over numeric and text information about hurricanes; (2) hurricane intensity was the parameter that was most commonly viewed and hurricane wind radius was the parameter that was least commonly viewed; (3)forecast track had a large number of clicks and long click durations, whereas uncertainty cone had fewer clicks but longer click durations; (4) participants' judgments of the extent to which they used each of the parameters were not entirely consistent with their search patterns; (5) participants found a hurricane's current location and day-5 forecast were the most informative time periods; (6) there was no evidence that participants' personal concern (whether a hurricane will head toward to their county or not) affected their information search pattern in this study; (7) participants failed to evacuate appropriate risk areas in timely manner; and (8) participants had difficulty interpreting strike probabilities. These results suggest the problem of misinterpretation of the uncertainty cone is less severe than some might have concluded from the evidence provided by Broad et al. (2007). Moreover, the results suggest that participants were able to utilize the available information in the tables and tracking maps to make reasonable judgments about each city's relative strike probability. However, their failure to take appropriate actions suggests a need for more comprehensive training on what actions to take in response to the hurricane information displays.

This book was released on 1995-07-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricane Andrew struck South Florida early on Monday morning, August 24, 1992. Widely described as the worst natural disaster in modern U.S. history, the storm left 38 people dead in South Florida, 80,000 homes destroyed, and damage estimates of at least $20 billion. The area devastated by the hurricane was approximately three times the size of Manhattan. Almost 250,000 people were left homeless by Andrew—roughly the population of the entire city of Las Vegas, Nevada. Garbage generated by the storm in a single night was equal to the projected landfill for Dade County for the next thirty years. Hurricane Andrew, the Public Schools and the Rebuilding of Community addresses the experience of the Dade County Public Schools—its teachers and students, administrators and staff—during the first school year following the storm. In particular, it examines the role of the schools in helping people cope with a disaster of the magnitude of Hurricane Andrew, and more specifically, with their role in rebuilding community.

Available in PDF, EPUB and Kindle. Book excerpt: ". . . the authors sound a pessimistic note about society's short-term memory in their sobering, able history of Camille" --Booklist "This highly readable account aimed at a general audience excels at telling the plight of the victims and how local political authorities reacted. The saddest lesson is how little the public and the government learned from Camille. Highly recommended for all public libraries, especially those on the Gulf and East coasts." —Library Journal online As the unsettled social and political weather of summer 1969 played itself out amid the heat of antiwar marches and the battle for civil rights, three regions of the rural South were devastated by the horrifying force of Category 5 Hurricane Camille. Camille's nearly 200 mile per hour winds and 28-foot storm surge swept away thousands of homes and businesses along the Gulf Coast of Louisiana and Mississippi. Twenty-four oceangoing ships sank or were beached; six offshore drilling platforms collapsed; 198 people drowned. Two days later, Camille dropped 108 billion tons of moisture drawn from the Gulf onto the rural communities of Nelson County, Virginia-nearly three feet of rain in 24 hours. Mountainsides were washed away; quiet brooks became raging torrents; homes and whole communities were simply washed off the face of the earth. In this gripping account, Ernest Zebrowski and Judith Howard tell the heroic story of America's forgotten rural underclass coping with immense adversity and inconceivable tragedy. Category 5 shows, through the riveting stories of Camille's victims and survivors, the disproportionate impact of natural disasters on the nation's poorest communities. It is, ultimately, a story of the lessons learned-and, in some cases, tragically unlearned-from that storm: hard lessons that were driven home once again in the awful wake of Hurricane Katrina. "Emergency responses to Katrina were uncoordinated, slow, and--at least in the early days--woefully inadequate. Politicians argued about whether there had been one disaster or two, as if that mattered. And before the last survivors were even evacuated, a flurry of finger-pointing had begun. The question most neglected was: What is the shelf life of a historical lesson?" Ernest Zebrowski is founder of the doctoral program in science and math education at Southern University, a historically black university in Baton Rouge, Louisiana, and Professor of Physics at Pennsylvania State University's Pennsylvania College of Technology. His previous books include Perils of a Restless Planet: Scientific Perspectives on Natural Disasters. Judith Howard earned her Ph.D. in clinical social work from UCLA, and writes a regular political column for the Ruston, Louisiana, Morning Paper.

Download or read book Hurricane Elena Gulf Coast written by National Research Council and published by National Academies Press. This book was released on 1991-02-01 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricane Elena, following an erratic and difficult-to-forecast course along an unusually large section of the Gulf Coast, posed special problems from New Orleans, Louisiana, to Sarasota, Florida, well before it came ashore on September 2, 1985. Considerable wind damage occurred in this area to structures that were ostensibly designed to resist such extreme wind conditions. Because similar design conditions and building control procedures exist along other U.S. hurricane-prone coasts, the conclusions drawn in this detailed book catalog the structural damage caused by the hurricane and emergency response actions, establish the wind conditions of the storm, review in-depth the building control process used in the area, and conduct necessary structural and wind tunnel tests relevant to a large number of communities along the coastal areas.
