Tornadoes are a relatively common natural disaster in the United States, with an average of over 1,200 tornadoes occurring each year. While tornadoes can occur in any state, there are certain areas that are particularly prone to tornado activity. In this response, we will explore which U.S. city has been hit by the most tornadoes.
Before diving into the data, it’s important to note that tornadoes can be difficult to track and categorize, and there are different ways to define and measure tornado activity. Some measures focus on the number of tornadoes that touch down within a certain radius of a city, while others look at the number of tornadoes that have directly hit a city. Additionally, different sources may have slightly different data due to differences in reporting and data collection methods.
With those caveats in mind, one city that often comes up in discussions of tornado activity is Oklahoma City, Oklahoma. Oklahoma City is located in what is known as Tornado Alley, a region in the central United States that is particularly prone to tornadoes due to its geography and climate.
According to data from the National Oceanic and Atmospheric Administration’s (NOAA) Storm Prediction Center, the Oklahoma City metropolitan area has been hit by 147 tornadoes between 1950 and 2017. This makes it the city with the second highest number of tornadoes in that time period, behind only the Dallas-Fort Worth, Texas metropolitan area, which has been hit by 155 tornadoes.
However, it’s worth noting that the NOAA data only looks at tornadoes that directly hit a city or its immediate suburbs. If we expand our definition to include tornadoes that occurred within 50 miles of a city, Oklahoma City moves into the top spot. According to data from the Tornado History Project, which tracks tornadoes based on their geographic coordinates, there have been over 400 tornadoes within 50 miles of Oklahoma City since 1950.
It’s also worth considering other factors beyond just the raw number of tornadoes. For example, some cities may have a higher population density or more vulnerable infrastructure that could make tornadoes more damaging. Additionally, some cities may have experienced particularly devastating tornadoes, even if they haven’t been hit as frequently overall.
One example of this is Joplin, Missouri, which was hit by an EF5 tornado in 2011 that killed 158 people and caused over $2 billion in damage. While Joplin has only been hit by a total of 7 tornadoes since 1950, the severity of the 2011 tornado means that it is often included in discussions of the most tornado-prone cities.
Another factor to consider is changes in tornado activity over time. While some cities may have historically experienced a high number of tornadoes, this could be changing due to factors such as climate change or urbanization. For example, a 2017 study published in the journal Environmental Research Letters found that the frequency of tornadoes in the southeastern United States had been decreasing over the past few decades, while the frequency in the central Great Plains had been increasing.
In conclusion, there is no clear answer to the question of which U.S. city has been hit by the most tornadoes. Depending on how you define and measure tornado activity, different cities could come out on top. However, Oklahoma City is often cited as one of the most tornado-prone cities due to its location in Tornado Alley and the high number of tornadoes that have occurred within a relatively close proximity.
