According to UNESCO, the likelihood of a big tsunami occurring over the next 30 years is nearly 100%, and it advises coastal cities to become “tsunami-ready.”
According to UNESCO, there is an almost 100% risk that a tsunami would strike a major city on or near the Mediterranean Sea over the next 30 years, including Marseille, Alexandria, and Istanbul.
As sea levels rise, there is an anticipated increase in the probability of a tsunami in Mediterranean coastal areas. Communities in the Pacific and Indian Oceans, where the majority of tsunamis occur, were frequently aware of the threats, but other coastal areas, like the Mediterranean, underestimated them, according to UNESCO.
