World Tsunami Awareness Day 2024, Its History, Objective & Causes

World Tsunami Awareness Day

On November 5th each year, communities across the globe come together to observe World Tsunami Awareness Day. This special day serves as a reminder of the significance of comprehending tsunamis, which are formidable natural disasters triggered by underwater disruptions such as earthquakes, volcanic eruptions, landslides, and even rare extraterrestrial impacts. While tsunamis are infrequent occurrences, they have a historical record of causing substantial loss of life. In light of World Tsunami Awareness Day, let’s delve into what tsunamis are, their root causes, and their connection to the global objective of diminishing inequality.

Understanding Tsunamis

Defining Tsunamis

The term “tsunami” originates from Japanese, combining “tsu” (harbor) and “nami” (wave). Tsunamis are famous for their massive ocean waves.

Formation and Characteristics

Tsunamis emerge as a result of underwater disturbances, encompassing earthquakes, volcanic eruptions, landslides, and even extraordinary extraterrestrial events. These waves can manifest as towering walls of water and persist as threats for hours, with recurring waves appearing every 5 to 60 minutes.

History and Objectives of World Tsunami Awareness Day

United Nations’ Initiative

In 2015, the UN General Assembly designated November 5 as World Tsunami Awareness Day with the objective of raising awareness about tsunamis and sharing innovative strategies for risk reduction.

Japan’s Leadership

Japan, owing to its extensive experience in tsunami early warning systems and disaster recovery, played a crucial role in launching World Tsunami Awareness Day.

Global Cooperation

International initiatives such as the Hyogo Framework for Action and the Indian Ocean Tsunami Warning and Mitigation System have been pivotal in reducing the risks associated with tsunamis.

Causes of Tsunamis

There are various causes of tsunamis and they are explained in the following points:

Tsunamis Triggered by Earthquakes

The majority of tsunamigenic earthquakes arise in subduction zones, where one tectonic plate descends beneath another. Four essential conditions must be met for an earthquake to initiate a tsunami: it should transpire beneath or close to the ocean, boast a substantial magnitude (at least 6.5 on the Richter Scale), rupture the Earth’s surface, and induce vertical movement on the seafloor.

Landslides and Tsunamis

Coastal landslides can shift significant volumes of water into the sea, prompting the creation of tsunamis. Similarly, submarine landslides beneath the ocean can result in tsunami generation.

Volcanic Eruptions as Tsunami Sources

Though rare, violent volcanic eruptions can displace substantial water volumes, producing highly destructive tsunami waves. The historical example of the 1883 Krakatoa eruption in Indonesia highlights this phenomenon.

Extraterrestrial Collisions and Tsunamis

Though incredibly uncommon, there exists a potential risk if celestial bodies collide with the ocean, leading to the displacement of vast amounts of water and, consequently, the formation of tsunamis.

Solution for World Tsunami Awareness Day

Growing Threats

Rapid urbanization and increased tourism in regions susceptible to tsunamis expose more people to these risks. Consequently, risk reduction becomes a fundamental goal in international agreements, such as the Sendai Framework for Disaster Risk Reduction.

Collaboration and Engagement

World Tsunami Awareness Day encourages diverse sectors of society to collaborate on disaster risk reduction, addressing both the causes and consequences of tsunamis. By promoting collaboration and understanding, we can work towards a more resilient and equitable future in the face of tsunamis and other natural disasters.

5th November 2024 Special Day

On November 5th, people around the world look forward to World Tsunami Awareness Day. This special day reminds us about the danger of tsunamis. Though rare, tsunamis are huge waves caused by earthquakes and can cause major damage. The upcoming 2024 day focuses attention on being ready for tsunamis and warning people in danger. It brings hope that by working together, we can build resilience against tsunamis. The goal is to protect all people in the future from the destruction tsunamis can cause.
