Reference excerpt

The following is a list of the deadliest tornadoes in the Americas including Canada, Mexico, and the United States as well as the countries and islands of the Caribbean and the countries included in both Central America and South America. While the significant majority of tornadoes on this list occurred in the United States, there are also entries for Argentina, Bermuda, The Bahamas, Brazil, Canada, Cuba, Mexico, Panama, and Uruguay. The deadliest tornado on record was the Daulatpur–Saturia tornado which occurred in the Dhaka division of Bangladesh on April 26, 1989. With a rating of at least F3 from the World Meteorological Organization and top winds estimated at greater than 200 mph (320 km/h), the tornado killed an estimated 1,300 people and injured at least 12,000 others. Of all the recorded tornadoes with death tolls of 100 or greater, at least 24 of them occurred in Bangladesh and/or India, and two of them occurred in Europe (in the countries of Italy and Malta). In the Americas, there are 15 tornadoes on record that caused at least 100 fatalities, the most recent being the Joplin EF5 tornado which killed 161 people in May 2011. There are at least 450 tornadoes on record that caused greater than ten fatalities; the most recent of these was the Somerset-London Kentucky EF4 tornado which killed 19 people in May 2025.

Worked examples

Example 1 — a first encounter with List of deadliest tornadoes in the Americas

Start with the simplest possible case. Write down what List of deadliest tornadoes in the Americas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of deadliest tornadoes in the Americas before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of deadliest tornadoes in the Americas ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of deadliest tornadoes in the Americas

In research: List of deadliest tornadoes in the Americas appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of deadliest tornadoes in the Americas in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of deadliest tornadoes in the Americas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Death-related lists, Deaths in tornadoes, Lists of natural disasters, so understanding it makes those chapters shorter.
