Parameter estimates obtained from the multinomial logistic regression model. In general, buildings designed with additional reinforcement, such as a reinforced concrete slab, wind bracing, impact-resistant glass windows, and steel-reinforced doors, have a better chance of surviving an F5 tornado than those that do not. Although rope tornadoes may look weaker than much larger ones, some get more intense as they narrow and tighten. ), which were not covered here, were associated with housing damage in previous studies [18,29]. 1:38. Furthermore, tornadoes can cause trees to be uprooted and hurled into buildings, causing additional damage. As a library, NLM provides access to scientific literature. Tornado - Wind Speed, Vortex, Destruction | Britannica The Ehnaced Fujita scale uses the damage done by a tornado to estimate its intensity, sorting . A building damage survey can provide basic information on the disaster resilience of buildings and facilitate the analysis of building damage [19,20].

In short, tornadoes have the potential to be incredibly damaging, often completely ruining homes and other buildings in their path. In addition, the building height is also a crucial indicator of building safety during wind-induced events. In addition, more than 99% of the houses were owned by the occupiers. The current study analyzed the influencing factors of housing damage in a tornado using a multinomial logistic regression model. and J.G. Adelekan [42] assessed 69 houses damaged by a windstorm event in Ibadan by interviewing residents to evaluate the houses vulnerability. Slightly damaged houses exhibited the highest correlation with environmental factors. Weights were assigned to the affected villages according to the number of buildings. Tornadoes can form anywhere the right .

If your home is damaged, you should call your insurance company as soon as possible. It is also commonly believed that in rural areas where the quality of housing is generally not as good as in cities, areas with a high building density may have more severe damage to houses during a tornado [36]. The building area, building material, and the number of building stories were correlated with the housing damage level [12]. Thus, the EF3 tornado caused less damage to houses than the EF4 tornado in the rural areas of Funing, although the damages were more likely to be linked to the EF1 or EF2 tornado than the EF4 tornado. Tornadoes can also bring intense rains and large hail, which can cause additional damage. Low-intensity tornados passing through areas with dense buildings cause more damage to houses than high-intensity tornados passing through areas with sparse buildings. Eight characteristics of buildings (roof, exterior wall, story number, year built, building area, floor, foundation, and shape) were used as indicators to establish a hurricane loss model. They occur in a wide variety of shapes and sizes and manifest as a funnel of condensation surrounded by a cloud of dust and debris. 2527 May 2012. However, mitigating the damage may significantly reduce the effects of hazards rather than improving the buildings resistance to violent tornados. Ultimately, it can take months or years to fully recover from a significant tornado, and the process of rebuilding can be a long and arduous journey. and transmitted securely. Thus, the serious damage to houses from this tornado might have been related to factors other than environmental factors in the rural areas of Funing. 52108053); the Social Science Foundation of Jiangsu Province (Grant No. Therefore, there may be some limitations in the comprehensiveness of the data collection. This finding demonstrates that the level of housing damage was not strongly correlated with the tornado intensity. Eventually, the RFD wraps itself around the tornado and cuts off the warm air supply, dissipating the wind funnel. Supercells contain a system of rotating winds called a mesocyclone, which exists high in the atmosphere and can be several miles across. The hot and humid summers provide favorable conditions for severe convective weather and tornados. [1] These families form a line of successive or parallel tornado paths and can cover a short span or a vast distance. USACE is currently helping to dispose of debris resulting from the tornadoes that hit Alabama this spring. Those who have been affected should always wait for first responders to examine the area before entering. Wind load factors for dynamically sensitive structures with uncertainties.
