What is Tsunami | Japan earthquakes | Indepth | Drishti IAS

Tsunami waves hit several parts of Japan’s coastal areas and urgent evacuation warnings were issued after a 7.6-magnitude earthquake shook the country’s north-central region on Monday (January 1).Japanese Prime Minister Fumio Kishida, in a televised address, asked citizens to follow evacuation orders closely and warned that more powerful quakes and tsunami waves might follow the initial ones. Tsunami (a Japanese word that means “harbor wave”) is a series of giant ocean waves caused by earthquakes or volcanic eruptions under the ocean. When an earthquake takes place under the ocean, a large chunk of the ocean floor can suddenly move upward or downward, leading to a sudden displacement of a large volume of water, thereby causing tsunami waves. Big tsunamis usually begin in the deep ocean, where a large volume of water can be displaced. As the wave moves closer to the shore, it grows taller as the ocean becomes shallower,” according to a report by NASA. Tsunami waves can be hundreds of feet tall and can travel as fast as jet planes over deep waters while slowing down when reaching shallow waters. However, not all earthquakes or volcanic eruptions lead to tsunamis. The formation of a tsunami can depend on a host of factors, including the shape of the ocean floor, and the earthquake’s distance and direction. That’s because of its location. Japan is situated along the ‘Pacific Ring of Fire’, which is the most active earthquake tectonic belt in the world. The ‘ring’ refers to “an imaginary horseshoe-shaped zone that follows the rim of the Pacific Ocean, where many of the world’s earthquakes and volcanic eruptions occur,” according to a report by Live Science. Within the Ring of Fire, there are different tectonic belts, including the Pacific Plate, Eurasian Plate, and Indo-Australian Plate, which keep meshing and colliding with each other, causing earthquakes, volcanic eruptions and tsunamis. In 2011, Japan was hit by a 9.0 magnitude earthquake and a resulting tsunami which devastated its northeastern coastal communities, killing around 18,000 people and displacing tens of thousands. Those tsunami waves led to a nuclear meltdown at the Fukushima power plant, causing the most severe nuclear accident since the 1986 Chernobyl disaster in the Soviet Union. =̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵ Subscribe Drishti Teaching Exams Channel :    / @drishtiteachingexams   =̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵=̵ NCERT कोर्स में नामांकन के लिये इस लिंक पर क्लिक करें : https://www.drishtiias.com/hindi/onli...
