World Tsunami Awareness Day is celebrated every year on November 5 to increase awareness about the dangers of tsunamis and encourage preparation in case a natural disaster strikes. Established by the United Nations General Assembly in 2015, this day reminds us that effective early warning systems and community education are needed to mitigate the devastating impacts of tsunamis.
Significance and History
This was done to commemorate Inamura-no-hi, which fell on November 5, 1854, wherein a tsunami was declared to hit following an earthquake by Japanese farmer Hamaguchi Goryō in his observation of the signs of the calamity. During this instance, he burnt his rice sheaves to alert the other people of his village of the approaching destruction. In this way, an early warning concerning communities being prepared in the event of a natural calamity can be seen.
This observation targets the sensitization of communities regarding the risks involving tsunamis because it shows more than 700 million people live in tsunami-prone coastal regions. Today also focuses on further international cooperation that would globally increase tsunami preparedness since population density along coastal areas is also growing.
Themes and Activities
World Tsunami Awareness Day has different themes every year. It promotes a proactive response to the situation. Last year 2022 for instance, the theme is #GetToHighGround. The theme encourages the communities to drill their evacuation plans. This includes holding education events, practicing drills, and using social media to disseminate information about tsunami safety and preparedness.
Historical Events
Some historical events underscore that tsunami awareness and preparedness are very important. Following are some key incidents of the lessons learned and response strategies:
1854 Nankai Tsunami, Japan
On November 5, 1854, a huge earthquake of 8.4 magnitude struck the Kii Peninsula in Japan, creating a devastating tsunami. Local elder Goryo Hamaguchi set rice sheaves on fire to drive villagers up the hills and away from the danger of the approaching tsunami. Many lives were saved, and his bravery became a piece of Japanese folklore. Today, the event is honoured by World Tsunami Awareness Day, reminding everyone of the need for preventive action in dealing with a tsunami.
2004 Indian Ocean Tsunami
One of the deadliest natural disasters in human history, the Boxing Day tsunami of December 26, 2004, killed over 230,000 people from 14 countries, while triggered by a gigantic undersea earthquake, 87 miles off the coast of Sumatra, Indonesia, exposed severe deficits in global tsunami warning systems. This disaster changed that.
Chilean 1960 tsunami
This tsunami was caused by the largest recorded earthquake, measuring 9.5 in Valdivia, Chile on May 22, 1960, and it extended to the coastal regions as far as Hawaii and Japan. The waves covered a distance of more than 10,000 kilometers with devastating damage and more than 2,000 fatalities. This disaster led UNESCO's Intergovernmental Oceanographic Commission (IOC) to establish the first Pacific Tsunami Warning System, indicating a need for international cooperation in tsunami preparedness.
Lessons Drawn
From these incidents, it is known that:
Early Warning System: An effective early warning system can save lives. This system will give warning messages to the risky population.
Campaigns about Tsunami: People are supposed to be informed that tsunamis are dangerous. These are possible only through information campaigns. Evacuation plans from tsunamis must be acquainted with the community.
Coordination at the Global Level: At times, tsunamis strike more than one nation. Therefore, coordination and sharing of information and material help in gathering resources will save lives and help in more preparation for tsunamis.
Current Situation
As we approach November 5, 2024, this year's celebration will be more meaningful since it falls on the 20th anniversary of the devastating Indian Ocean tsunami of 2004 that claimed over 230,000 lives in several countries. The UN Secretary-General has emphasized that education is a lifesaver and that young people's engagement in tsunami preparedness is crucial.
The World Tsunami Awareness Day serves not only as a memorial to previous tragedies but also as a proactive initiative to equip communities with the knowledge and tools needed to respond effectively to future tsunami threats.
