Fun Facts on Tsunami

Fun Facts For Kids

Did You Know?
Did you know that Tsunamis were once thought of as tidal waves? It was then discovered that tsunamis are not related to tides at all. Did you know that the first historian to associate tsunamis with underwater earthquakes was the Greek historian Thucydides (460-395 BC)? Tsunamis affecting the British Isles are extremely uncommon; however did you know that around 5800 BC the east coast of Scotland was struck by tsunami?

Fun Fact 1: What does the word Tsunami mean? The definition of Tsunami (pronounced soo-nah-mee); it is a Japanese word that means harbour wave

Fun Fact 2: What is a Tsunami? A Tsunami is a sequence of huge waves of water that usually occur in oceans or large lakes

Fun Fact 3: What causes a Tsunami? Tsunamis are caused by geological disturbances within the surrounding areas; they are usually caused by underwater volcanic eruptions, earthquakes and landslides

Fun Fact 4: How do tsunamis form? When the plates on earth's crust move due to a geological disturbance, energy is created which displaces the water to form a wave, as the wave moves it increases in size. Most tsunamis are very small and go un-noticed. Large, powerful tsunamis do not create immediate giant waves, they travel towards shore in a similar way to a tide, often pulling back from the coastline a distance of hundreds of meters, a clear sign that a big tsunami is on its way. Then when the tsunami hits shallow water it increases in height, before crashing into the shoreline potentially causing havoc

Fun Fact 5: Tsunami waves can be so small that they almost not be noticed, however, some waves have been recorded at measuring extreme heights of up to 38 meters high (125 ft)

Fun Fact 6: The most deadly natural disasters in human history was caused by a Tsunami! On December 26, 2004 Tsunami hit the west coast of Sumatra, Indonesia. It was triggered by an earthquake under the Indian Ocean and was catastrophic; it caused over 240,000 deaths in fourteen different countries

Fun Fact 7: What is the Speed of a Tsunami? The ocean speed of a tsunami can reach over 970 kph (600 mph); a similar speed to that of an aeroplane

Fun Fact 8: On March 11 in 2011 a tsunami hit Japan's north-east coast, about 250 miles (400km) from Tokyo. It was caused by an earthquake 250 miles from island Honshu. Waves from Japans tsunami were recorded as measuring an incredible height of approximately 30-38 meters (100-125 ft). The 2011 Japanese tsunami killed over 18,000 people and devastated the area for hundreds of miles

Fun Fact 9: About 80 percent of tsunamis are due to geological volcanic disruptions that occur within an area in the Pacific Ocean this area is called the 'Ring of Fire'

Fun Fact 10: Some states in the U.S. are recognised for being at risk to tsunamis; these include Hawaii, Alaska, Washington, Oregon, and California

Fun Fact 11: The U.S. state at greatest risk for a tsunami is Hawaii. Hawaii is formed of five volcanos and is home to the largest volcano in the world, Mauna Loa. The name Mauna Loa means Long Mountain

Fun Fact 12: On average Hawaii experiences one tsunami a year and a severe tsunami every seven years.  The worst tsunami to hit Hawaii occurred on April 1 1946, it was caused by an earthquake near the Aleutian Islands. The tsunami consisted of 30 foot waves that travelled at approximately 805 kph (500 mph)

Fun Fact 13: Modern technology can detect when a tsunami is likely to have. Seismographs are offshore computers that detect changes in wave heights; it can then send signals and trigger sirens to alert people on land

Fun Fact 14: Areas that are in tsunami risk zones and are prone to danger have warning systems in place; these give people time to prepare and evacuate before the tsunami hits

Fun Fact 15: Major tsunamis cause catastrophic damage to the environment. They cause injury and death, and devastate the environment and wildlife. The salty sea water can infiltrate soil and groundwater systems poisoning freshwater, this causes suffering, starvation and disease long after the tsunami has gone
