Knowing the wind speed zone by using the Fujita scale prediction of building damage due to the brunt tornado (winds) in District Tanon, (2). Knowing agihan building vulnerability to cyclones in District Tanon, (3). Analyze the vulnerability of buildings to wind velocity zone in District Tanon and (4). Analyze the vulnerability of buildings to damage buildings that have occurred due to the brunt tornado in District Tanon.
