Interesting facts about tsunamis The most common causes of tsunamis are underwater earthquakes, volcanic eruptions, and landslides. The literal translation of “tsunami” from Japanese is “big wave in the bay.” Tsunamis most often occur in the Pacific and Indian Ocean. As far back as the 5th century B.C., the Greek historian Thucydides attributed the appearance of tsunamis to underwater earthquakes.

7 Interesting Facts about tsunamis

1. Tsunamis hit the coast not in one wave, but in a series. The first wave is not always the most destructive. Therefore, people who try to return home after the first wave hits are making a big mistake. The speed of waves in the ocean can reach 900 kilometers per hour. As you get closer to shore, the speed decreases significantly.

2. The incredible speed of the killer waves is one of the main reasons why seismologists simply do not have time to warn people in the regions where a tsunami is about to hit. On May 22, 1960, a powerful tsunami struck 160 kilometers off the coast of Chile. Already in 15 minutes, the waves reached the coast.

3. Many animals can predict tsunamis. For example, in 2004, tourists were quietly riding elephants in Thailand. Suddenly, the animals became nervous and, despite the commands of the herdsmen, rushed away from the shore. And a few minutes later, powerful waves crashed here.

4. Interestingly, the palm trees withstood the invasion of the tsunami. When everything around them collapses and other types of trees are torn out by the roots, the palm trees remain virtually unscathed. The palm’s branched root system is an excellent counterbalance. And the trunk of these trees are very flexible, and even tsunamis and hurricane winds are hard to break it.

5. In Europe, tsunamis do not strike often. But, in 1755, the Portuguese city of Lisbon was almost completely destroyed. According to documents, the victims of the tragedy were about 60,000 people. Sailors visiting the port after the tsunami simply did not recognize it. This catastrophe was one reason why Portugal lost its title of great maritime power.

6. Asteroid 20002 Tillismith got its unusual name after 10-year-old English girl Tilly Smith, who was vacationing with her parents in Thailand in December 2004. At school, she remembered that before a tsunami, the water could move sharply away from the shore. Noticing such a phenomenon on the beach, Tilly warned her parents, and they warned the hotel staff. Thanks to a timely evacuation, casualties were avoided.
