The latest tsunami caused global attention, especially after the incident in the Pacific Ocean region. This natural phenomenon, the result of an underwater earthquake, has tremendous devastating potential. The impact is not only felt by nearby countries, but can also affect marine ecosystems and human life throughout the world. In the context of impact, infrastructure damage is one of the main focuses. Tsunami waves can destroy buildings, roads and bridges in a short time. For example, during the tsunami in Sulawesi, thousands of houses were destroyed and thousands of residents lost their homes. The economic losses resulting from this damage amount to billions of dollars, which will take years to recover. Not only physical, but the psychological impact is also significant. Surveys show that many victims experience prolonged trauma. Children, in particular, are vulnerable to the lasting emotional effects following a disaster. Therefore, mental rehabilitation programs are crucial for survivors. The global response to tsunamis is also evolving. Experienced countries, such as Japan and the United States, provided technical assistance and resources to the newly shaken country. International organizations such as the UN and the Red Cross play an active role in providing humanitarian assistance. This includes delivery of food, medicine and psychological support. Technology is also an important part of the tsunami response. Increasingly sophisticated early warning systems help minimize loss of life. For example, the use of seismic and water wave sensors can detect possible tsunamis quickly. Every second is valuable in saving lives, so the integration of technology in disaster management becomes very important. Public education is also no less important. Awareness campaigns about the dangers of tsunamis help residents understand how to protect themselves and their families. Periodic evacuation training and simulations increase community preparedness. Government and non-governmental organizations collaborate to hold seminars and workshops. In terms of natural habitat, tsunamis also have significant environmental impacts. Changes in the shape of beaches, damage to coral reefs, and pollution with hazardous materials can disrupt marine ecosystems. Research shows that ecosystem recovery takes a very long time, and therefore, conservation efforts must be undertaken. The importance of cross-sector support was also revealed in handling the tsunami impact. Cooperation between countries, research institutions and civil society organizations strengthens disaster management capacity. Sustainable post-disaster recovery must include social, economic and environmental aspects. Given all these challenges, it is important for the international community to be proactive in responding to tsunamis and other disasters. Investments in disaster-resilient infrastructure, development of mitigation technologies, and increased public awareness are the keys to a safer future. Collaborative initiatives at the global level are expected to create a better system in dealing with the tsunami threat.
