World Tsunami Awareness Day is designed to raise awareness, promote understanding, and encourage preparedness for tsunami threats worldwide. Endorsed by the United Nations, the day focuses on sharing knowledge about effective actions, policies, and practices to mitigate the potentially devastating impacts of tsunamis. Addressing and managing the risks associated with tsunamis is essential to reduce fatalities and promote resilient communities globally.
Initially proposed by Japan in 2015, the history of World Tsunami Awareness Day is rooted in the 1854 Ansei-Nankai earthquake and subsequent tsunami that hit the coastal regions of Kii Peninsula, Japan. Countries worldwide decided to unite and educate their populations on evacuation and prevention of tsunamis. The United Kingdom plays an essential role in providing scientific support and expertise through organizations such as the British Geological Survey and the National Oceanography Centre. These institutions contribute to the global understanding of tsunami risk, benefit from shared knowledge, and help the UK to be prepared for the remote possibility of a tsunami affecting the British coastline.
World Tsunami Awareness Day is commemorated in the United Kingdom through a range of activities such as public awareness campaigns, educational workshops, and expert-led discussions. These events align with the global aim to increase awareness and preparedness. For instance, the UK has hosted conferences on tsunami risk assessment, early warning systems, and evacuation planning. In addition to these observances, the United Kingdom participates in the global effort to reduce the loss of lives and economic damage caused by tsunamis. World Tsunami Awareness Day takes place annually on the 5th of November, a date chosen to honour the memory of the aforementioned 1854 Japanese Ansei-Nankai tsunami.
