The Tri State Tornado A tornado is a violent destructive whirling wind accompanied by a funnel-shaped cloud that progresses in a narrow path over the land.1 I chose to do my topic on the Tri State Tornado. This tornado was the deadliest and it had the longest tornado track in U.S history. Also, this tornado caused the most injuries in U.S history. Tornadoes are studied by meteorologists. Meteorology is a branch of Earth Science, because it’s the study of the atmosphere.2 This relates to Earth Science because it is the study of any sciences (such as geology, meteorology, or oceanography) that deal with the earth or with one or more of its parts.3 I chose to do this event because tornadoes are some of the most dangerous forces of nature. This specific tornado was the deadliest tornado recorded in history. This newspaper picture shows how devastating the Tri-State-Tornado was to the town of Murphysboro. There was a total of 234 that were killed, which is also the most tornadic deaths in a single city in U.S. history. On March 25, 1925 a dark, grueling and dangerous force touched down about three miles northwest of Ellington, Missouri.4 Along with this tornado came a string of many more, but not as strong or intense as this one. Its name was the Tri State Tornado. The Tri State Tornado got its nickname because it traveled through three states. These three states include Missouri, Indiana, and Illinois.5 The tornado also holds the record for longest tornado track which is 219 miles and longest duration of 3.5 hours.6 The Tri State Tornado wreaked havoc in its wake through cities, towns, and small villages. So much so that as I stated before, giving it, the title of the deadliest tornado ever recorded in United States history.7 Also, giving it itself, the most injuries sustained because of it in United States history as well. This tornado was rated a F5 on the Fujita Scale. The Fujita Scale measures the strength of tornadoes by how high the miles per hour winds are.8 This chart represents the Fujita Scale. This scale measures the wind speed of a tornado by miles per hour going from 40 mph winds at a F-0, to 318 mph winds at a F-5. The Tri State Tornado destroyed, devastated, and killed many people. This natural disaster was really a big disaster. It had a very large negative impact on many people’s lives. The Tri State Tornado obliterated whole towns, sent thousands to the hospital, and killed more than twice the number of people lost in the next deadliest tornado in U.S. history.9 This tornado was so deadly because the newscast did not partake in tornado forecasting.10 They weren’t even aloud to say the word tornado because it would cause the public to panic.11 Perhaps if the news had been spread, many lives could have been saved that day. This disastrous event was not all evil though. The Tri State Tornado helped scientists further develop the knowledge of tornadoes, and get a better grasp upon the nature of tornadoes. Even though this tornado was very destructive it helped scientists further understand and explore the nature of tornadoes. It helped them understand how tornadoes form and how destructive they can be. Also, that multiple tornadoes can happen at relatively the same time, close to the same place, and with different strengths. This picture shows the Tri-State-Tornado’s path of destruction through the three states of Missouri, Illinois, and Indiana. As I stated before a tornado is a violent destructive whirling wind accompanied by a funnel-shaped cloud that progresses in a narrow path over the land.12 About 1,200 tornadoes hit the United States a year.13 Missouri, Illinois, and Indiana are all located in the upper mid-west.14 The mid-wests’ tornado season usually happens in June through July, but tornadoes can strike any time of the year.15 The Tri State Tornado proved this statement to be true because it happened in March. Scientists actually don’t have a direct understanding of how tornadoes form. Though they’ve seemed to figure out that tornadoes usually occur during a large thunderstorm. Usually a thunderstorm with a mesocyclone.16 A mesocyclone is a well-defined radar circulation.17 On March 25, 1925 the Tri State Tornado absolutely impacted the lives of the people living in the towns, or cities that were in the tornadoes destructive path. This tornado was definitely Mother Nature’s destructive side. The Tri State Tornado had the longest path, most injuries, and most deaths in all of U.S history.
