World Tsunami Awareness Day

World Tsunami Awareness Day is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand World Tsunami Awareness Day rather than just read about it. In short: World Tsunami Awareness Day is an annual event held on 5 November to raise awareness of the dangerous effects of tsunamis and the importance of tsunami preparedness and early warning of tsunamis. It was first established in 2015 by United Nations General Assembly Resolution 70/23.

Key takeaways

World Tsunami Awareness Day belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect World Tsunami Awareness Day to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of World Tsunami Awareness Day from memory before moving on to harder problems.

Reference excerpt

World Tsunami Awareness Day is an annual event held on 5 November to raise awareness of the dangerous effects of tsunamis and the importance of tsunami preparedness and early warning of tsunamis. It was first established in 2015 by United Nations General Assembly Resolution 70/23. On this day events are held in various countries and people are encouraged to spread awareness on social media. Tsunami awareness is very important as in the past 100 years there have been a total of 58 tsunamis with a combined death toll of over 260,000 people. Between 1998 and 2018 $200 billion was lost due to tsunamis. There is a potential for tsunami death tolls to increase in the future due to the combined effects of population increase in coastal areas and sea level rise. The official theme of World Tsunami Awareness Day 2022 is "#GetToHighGround" which encourages people to practice tsunami evacuation plans, with walks organised in Portugal and Mauritius.

History World Tsunami Awareness Day was established by United Nations General Assembly Resolution 70/203 on 22 December 2015. This day was requested specifically by the Japanese delegation as it was the day of the traditional Japanese tale of The Fire of Rice Sheaves, which remembers the actions of Hamaguchi Goryō. Hamaguchi Goryō protected his village of Hiro from a tsunami that followed the 1854 Nankai earthquake by burning his rice crop to warn and guide the villagers to safety. Yuki Matsuoka, the head of United Nations Office for Disaster Risk Reduction in Japan stated that:

Rather than selecting a memorial day or a tragic day, such as 11 March or 26 December, 5 November was selected as a ‘forward-looking’ day when many lives were saved due to proactive actions. Hamaguchi Goryō later built a 5 meter high seawall which protected the village from the tsunami of the 1946 Nankai earthquake. This action, as well as the fact that he hired the tsunami victims to build it, has led to him becoming a model for tsunami awareness, prevention, and recovery.

Worked examples

Example 1 — a first encounter with World Tsunami Awareness Day

Start with the simplest possible case. Write down what World Tsunami Awareness Day claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 World Tsunami Awareness Day 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 World Tsunami Awareness Day 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 World Tsunami Awareness Day

In research: World Tsunami Awareness Day appears in 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 World Tsunami Awareness Day 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: World Tsunami Awareness Day is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2015 introductions, Civil awareness days, November observances, so understanding it makes those chapters shorter.
In everyday life: Look for World Tsunami Awareness Day outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
