The states with the most weather-related disasters topping more than $1 billion are Texas, Missouri, Alabama, Georgia, Tennessee and South Carolina, which each had at least 31 expensive events in the past 30 years.
24/7 Wall St. replicated the methodology and aggregated RealtyTrac county-level data on a metropolitan level. For each type of natural disaster, the likelihood of risk is assigned either as very low, low, moderate, high, or very high. These are the cities with the most dangerous natural disasters. Americans living in the Gulf or the Atlantic Coast are aware that such risk of a hurricane damaging their property exist. Similarly, those living on or near the San Andreas Fault can expect at least a minor earthquake in their lifetimes.
