Tsunamis are devastating natural phenomena and can result from a variety of causes, including earthquakes, volcanic eruptions, or marine landslides. The world’s latest devastating tsunami occurred in several important locations, causing significant impacts on local residents and the environment. One of the most striking is the tsunami that hit New Zealand in September 2023. Known as the Fiordland tsunami, this event was triggered by an earthquake measuring 7.2 on the Richter scale located at a depth of 12 km. Tsunami waves reached heights of up to 8 meters within hours of the earthquake, resulting in mass evacuations in coastal areas and severe damage to infrastructure. In Indonesia, on the afternoon of September 23 2023, a tsunami occurred after an earthquake rocked the island of Sumatra. With a strength of 8.1 on the Richter scale and the epicenter located in the sea, the resulting tsunami waves hit coastal areas at high speed. The Aceh and Bengkulu areas were the most affected, where hundreds of houses were damaged and thousands of people were forced to flee. SAR teams and volunteers rushed to the location to provide assistance, while the local government tried to speed up the recovery process. Japan also did not escape the latest tsunami disaster. In August 2023, very large waves were triggered by seismic activity in the Pacific Ocean, putting port workers and fishermen at high risk. Although there were no reports of serious injuries, the evacuation process took place quickly to avoid casualties. Increasingly sophisticated research and technology related to tsunami detection are used by these countries to minimize risks. Better early warning systems are now able to inform local residents within minutes of an earthquake. Throughout the world, preventive measures have been taken, such as educational programs for coastal communities on how to act in the event of a tsunami. Social media plays an important role in quickly sharing information about the latest tsunami. Many social media users provide live updates, allowing the public to get the latest news and know the affected areas. However, the need for accurate information is very important so as not to cause panic. Building tsunami-resistant infrastructure is also an important focus. Tsunami-prone countries are now investing in engineering techniques for buildings and drainage systems to better withstand large waves. Research into tsunamis continues, improving our understanding of wave behavior and the most effective ways to protect life and property. The existence of mitigation systems, such as evacuation routes and shelters, is now standard in tsunami-prone areas. These rapid response steps are needed to reduce the impact of a disaster when a tsunami occurs. Training programs for authorities and local communities continue to be carried out to increase alertness. With many tsunami events in the near future, it is important for people in areas at risk to remain alert and prepared. Appropriate information and education about tsunamis can be a lifesaver, helping to reduce losses and keep residents safe when a disaster strikes.
