The United States experienced a significant surge in tornado activity in 2024, with 1,910 reported across the country. This marked a substantial increase from previous years, highlighting the unpredictable nature of these violent atmospheric phenomena. Fatalities and economic impact While tornado frequency increased, the death toll from such events remained relatively low compared to historical peaks. In 2023, 86 fatalities were reported due to tornadoes, a notable increase from the 23 deaths in 2022 but far below the 553 lives lost in 2011. Moreover, the economic impact of these storms was substantial, with tornado damage in 2023 amounting to approximately 1.38 billion U.S. dollars, nearly doubling from the previous year. However, this pales in comparison to the record-setting damage of 9.5 billion U.S. dollars in 2011. Comparison to other extreme weather events While tornadoes pose significant risks, hurricanes have historically caused more extensive damage and loss of life in the United States. Hurricane Katrina in 2005 remains the costliest tropical cyclone in recent decades, with damages totaling 200 billion U.S. dollars when adjusted to 2024 values. The impact of such extreme weather events extends beyond immediate destruction, as evidenced by the 1,518 hurricane-related fatalities recorded in 2005. As climate change continues to influence weather patterns, both tornado and hurricane activity may see further shifts in frequency and intensity in the years to come.

Texas was the state with the highest number of reported tornadoes in the United States in 2024, with 169 disasters reported. Iowa followed second, with 131 tornadoes reported. The same year, the number of tornadoes in the U.S. increased relative to previous years, with 1,910 reported in the country.

In 2023, there were a total of 86 fatalities reported due to tornadoes in the United States, up from 23 fatalities in the previous year. This was the lowest figure reported in the North American country since 2018, when a total of 10 lives were lost due to tornadoes. On the other hand, the highest figure reported in the U.S. since 1995 was in 2011, when tornadoes caused 553 fatalities.

This table contains a summary of the number of tornadoes by year for the United States. The table also provides summary statistics for fatalities, injuries, magnitude, and crop losses by hour. The data should be downloaded and used in a spreadsheet program like Excel, Numbers, or Google Sheets. Data is derived from Tornado data from the National Weather Service.

Data is from National Centers for Environmental Information's Storm Events Database.

Inspiration

I am curious about the trend of sever weather occurring in the United States over time. This started with tornadic events but will evolve to severe thunderstorm and hail events as well.

In 2023, tornadoes resulted in approximately 1.38 billion U.S. dollars worth of damage across the United States. This was an increase of almost 95 percent in comparison to the previous year. The North American country's economic damage caused by tornadoes peaked in 2011, at nearly 9.5 billion U.S. dollars. That same year, the number of fatalities due to tornadoes in the United States was also the highest.

This statistic shows the number of natural disasters that occurred in the United States from 1900 to 2016, by type of disaster. There have been 24 heat waves in the United States from 1900 to 2016.

Natural disasters in the United States

The United States ranks second among countries with the most natural disasters. In 2015, a total of 22 natural disasters occurred in the U.S. Only China, with a total of 36 disasters in 2015, suffered from more natural disasters.

Most natural disasters on U.S. territory are of meteorological nature. For example: during the period from 1900 to 2016, about 106 tropical cyclones hit the U.S. coast. During that period 40 earthquakes and 2 tsunamis hit the U.S. A total of 13.5 million people were directly affected by the aforementioned 106 tropical cyclones.

Tornadoes also frequently affect the United States. In 2016, the U.S. was struck by about 971 tornadoes. Tornadoes are more common in the United States than in any other country. Tornadoes mostly strike east of the Rocky Mountains, in the so-called “Tornado Alley” stretching from northern Texas through Oklahoma, Kansas and Nebraska. Most of the storms occurred during tornado season, which lasts from March to August. In 2015, tornadoes caused economic damages totaling about 320 million U.S. dollars.

Aside from meteorological disasters, wildfires also cause a formidable amount of economic damage in the United States, destroying property and threatening lives. In 2016, there were about 68 thousand wildfires in the United States.

The core breeding range of Swainson's warbler (Limnothlypis swainsonii) overlaps a zone of exceptionally high tornado frequency in southeastern North America. The importance of tornadoes in creating breeding habitat for this globally rare warbler and other disturbance-dependent species has been largely overlooked. This paper estimates tornado frequency (1950–2021) and forest disturbance in the 240 counties and parishes in which breeding was documented from 1988 to 2014. The frequency of destructive tornadoes (EF1-EF5) varied 6-fold across the breeding range with a peak in the Gulf Coast states. Counties from east Texas to Alabama experienced the lowest median return interval of 5.4 years per 1000 km2, resulting in approximately 2477 ha of forest damage per 1000 km2 per century, based on current forestland cover. Tornadoes were significantly less frequent north and east of the core breeding range, with return intervals increasing to 9.1 years per 1000 km2 for breeding counties on the Atl..., Geolocation of territorial Swainson's warblers. From 1988 to 2014, I surveyed breeding populations in 15 states as part of a comprehensive study of the warbler’s natural history. These surveys targeted Swainson’s warbler and were not incidental components of broader community censuses. Territorial males were documented in 240 counties and parishes documented by song recordings. Surveys were conducted during the breeding period, which began on 22 April in the Gulf Coast states and ended on 30 June in the Appalachian Mountains. I surveyed a wide spectrum of forestland and shrubland habitats, broadly classified as “forest land†by the USDA on public and private land and along waterways. Most breeding territories of this monogamous species were located using playback of songs, utilizing a protocol that was field-tested and fine-tuned in the late 1980s on the breeding and wintering ranges. Territorial males respond to playback by approaching the song source and delivering agitated “chip†not..., , # Catastrophic storms, forest disturbance, and the natural history of Swainson’s warbler

Description of the data and file structure

The spreadsheet presents the song recording field number, location (state and county or parish), date, and geographic coordinates of 1717 territorial Swainson's warblers (Limnothlypis swainsonii) documented from 1986 to 2014 in the southeastern United States. Records are ordered by state, county or parish, date, and song recording field number. All recordings were made by the author.

This ranking shows the ten deadliest tornadoes in U.S. history, ranked by the death toll of their victims. The deadliest tornado of all time in the United States was the Tri-State Tornado on March 18, 1925 in Missouri, Illinois and Indiana. It killed 695 people and injured over 2,000.

In 2023, there was a global protection gap of 262 U.S. dollars for natural disasters worldwide. The estimated economic loss of natural disasters worldwide was 380 billion U.S. dollars, while the estimated insured loss amounted to 118 billion U.S. dollars.Where did the most costly natural disaster occur?Natural disasters are extreme, sudden catastrophes that are caused by natural processes by the earth. Different types of natural disasters include floods, hurricanes, tornadoes, earthquakes, and tsunamis. There are many consequences that occur as a result of natural disasters, which include death, economic and infrastructural damage, and public health issues. The 2011 earthquake and tsunami that happened in Japan caused the most economic damage worldwide in the past four decades. Most costly disasters for insurersThe impact of natural disasters on insurance companies varies depends on the prevalence of insurance coverage in the affected region. Generally, losses from natural disasters that occur in wealthy countries such as the United States include a greater percentage of insured losses than disasters that occur in lower income countries. 2017 remains the worst year for insured property losses in the United States due to several major hurricanes in the U.S. and the Caribbean. Domestically, Hurricane Katrina was the most expensive natural disaster of all time.
