World Tsunami Awareness Day: November 5

Published on November 08, 2018
The World Tsunami Awareness Day is observed every year across the world on 5 November to spread awareness among people across the world about Tsunami.
World Tsunami Awareness Day: November 5
  • This year, it was the third edition of World Tsunami Awareness Day after it was instituted in 2015.
  • 2018 World Tsunami Awareness Day is aligned with International Day for Disaster Reduction (observed on 13 October) and "Sendai Seven Campaign".
  • It focused on Target "c" of Sendai Framework for Disaster Risk Reduction which aims at reducing direct disaster economic loss in relation to GDP.

Aim of the Day:

  • To spread awareness among people across the world in matters related to the dangers of Tsunami.
  • To stress on importance of early warning systems in order to mitigate damage from the devastating natural calamity.

One must know:

  • The World Tsunami Awareness Day was designated by United Nations General Assembly (UNGA) by adopting a resolution in December 2015.
  • The proposal was first mooted by Japan after the 3rd UN Conference on Disaster Risk Reduction held in Sendai (Japan) in March 2015.
  • This day coincides with the annual anniversary of the 1854 Inamura-no-hi (Fire of Inamura) event.
  • On this day in 1854, a villager in Wakayama Prefecture in Japan through his quick action had saved countless lives after he had set fire to sheaves of rice on the top of a hill, thus warning people of the imminent danger of a Tsunami.
  • This was the first documented instance of a Tsunami early warning.

About Tsunami:

  • Tsunamis are large waves that approach crashing on coasts due to seafloor movement, majorly associated with landslides or earthquakes.
  • The word "Tsunami" gets its name from the Japanese words- "Tsu" means harbor and "Nami" means wave.
  • Tsunami is a chain of huge waves created by disturbance underwater.
  • These waves are normally associated with earthquakes taking place under or around the ocean.
  • Other causes of Tsunami may be submarine landslides, coastal rock falls, volcanic eruptions or extraterrestrial collision.
  • Like many other natural disasters, it is difficult to predict Tsunamis but it can be suggested that seismically active areas are more at risk.
  • Tsunami waves are highly dangerous and generally look like strong walls of water.
  • The strong waves can attack seashore for hours, thereby destructing thousands of lives.
