Significance Of The World Tsunami Day 2020!

Amidst all the changes taking place, people are sensitized to the uproar of nature, such as natural disasters. Keeping this in mind, the United Nations General Assembly tasked the UN Office for Disaster Risk Reduction (UNDRR’)  to observe 05th November as World Tsunami Awareness Day’ to promote global awareness of tsunamis. Although tsunamis are rare, good planning can save lives and infrastructure.

What Are Tsunamis?

There are two types of tsunamis warnings:

  1. Official Warnings: These warnings are generally broadcasted through radio, television and other mediums. The Tsunami Early Warning Centre is at the Indian National Centre for Ocean Information Services (INCOIS) in Hyderabad. One of the Indian Ocean Tsunami Warning and Mitigation System (IOTWMS) is in Telangana.
  2. Natural Warnings: These warnings would be a strong earthquake, a roar from the ocean and unusual ocean behaviour.

Let’s Learn About The World Tsunami Day 2020!

·       The Intergovernmental Oceanographic Commission (IOC) of UNESCO works to raise awareness of national and regional early warning of tsunamis. Besides, IOC takes action, constructs policies and practices to reduce exposure to disaster risk through its procedures for the global oceans.

·       The IOC is the United Nations body responsible for supporting global ocean science and services.

·       While tsunamis are rare, they are often sudden and deadly as compared to any other hazard.

·       In tsunami-prone areas such as countries in Asia, South America and the Caribbean, the general population and coastal communities are educated about the risks and warning signs.

·       These initiatives help people to take prompt action to evacuate to a safe space.

·       26 communities in 15 countries are ‘Tsunami Ready’.

·       Over 700 million people live in low lying coastal areas and are exposed to extreme sea-level events.

·       The authorities have been investing in resilient infrastructure, early warning systems, and critical literacy to save people from any future risks.

·       MIPT researchers Leopold Lobkovsky and Raissa Mazova, and their young colleagues from Nizhny Novgorod State Technical University have improved the model of a landslide-induced tsunami. The highest and most devastating waves result from onshore landslide masses. This realization focused the attention on the past to predict the future. The recent tsunamis have been unusually large and have been accompanied by seismic events. Many landslide-tsunami models have been developed, of which two are commonly used namely the rigid-block models and viscoplastic.

·       In 2015, in Alaska, another massive landslide was triggered by either an earthquake or higher than average rainfall. This released an enormous amount of energy and was registered at a magnitude 4.9 earthquake.

·       Since 1900, there have been confirmed eight massive waves where large landslides have generated waves larger than 30 metres high.

·       Climate change has been attributed to the influence of the frequency and magnitude of these events.

·       Successful campaigns have been seen across the world, to mention a few:

1.       In Odisha, the communities practice regular drills. Having a local and national plan can save lives.

2.       In Corn Island, Nicaragua, children know what to do and where to go in case of a tsunami.

Having a plan and sharing it with everyone saves lives against the worst tsunamis.

Theme Of The World Tsunami Awareness Day 2020

·       In 2020, a 30-day campaign with critical events focused on Global Target E of the Sendai Framework: Substantially increase the number of countries with national and local disaster risk reduction strategies by 2020. The two key components essential to set up effective maintenance of risk reduction strategies are the adoption of scientific expertise and indigenous knowledge and memory.

·       The Sendai Framework for Disaster Risk Reduction 2015-2030 was adopted in 2015 at the Third United Nations World Conference on Disaster Risk Reduction.


Here Is How You Can Respond To Tsunamis:

·       If you have received an alert and you are in a tsunami-prone area, you need to stay away from any water bodies.

·       Gather all the information you can through relevant sources.

·       If you need to vacate an area, do it promptly.


What Should You Do After A Tsunami?

·       Stay away from tsunami zones until declared safe.

·       Keep away from any shaky infrastructure.

·       Only accept safety instructions from reliable sources.
