The United Nations General Assembly declared November 5 as World Tsunami Awareness Day in December 2015, urging governments, international organizations, and civil society to increase tsunami awareness and exchange innovative risk-reduction strategies.
World Tsunami Awareness Day Theme: In 2021, World Tsunami Awareness Day will promote target (f) of the “Sendai Seven Campaign,” which intends to “substantially enhance global cooperation to emerging nations through adequate and sustainable support to complement their national actions for implementation of the current Framework by 2030.”
Tsunamis are one of nature’s most destructive forces. Unsurprisingly, many of the tsunami-affected nations are islands, that have more susceptible coastlines than landlocked ones. These nations are located in the Pacific Ocean’s “Ring of Fire,” a region prone to earthquakes and volcanic eruptions. Scroll through to get a list of the nations worst hit by tsunamis.
The 2011 tsunami in Japan was so powerful that its aftershocks were felt as far away as Norway and caused debris to wash up on North American coasts years after the devastating event. The tsunami, which killed over 15,000 people, was caused by a magnitude 9.0 earthquake.
- United States
The exposed coastlines of the United States’ West Coast are the most tsunami-prone region in the country. Tsunamis even as far away as Russia and South America have wreaked havoc on the states of California, Oregon, and Washington. Meanwhile, Alaska is located in one of the world’s most hazardous seismic zones, and this was the location of the greatest tsunami ever recorded, with waves surpassing 1,722 feet.
In 2004, a disastrous tsunami triggered by a major earthquake caused catastrophic losses in Indonesia. Over 200,000 people were killed, and the monetary damages topped $10 billion.
Greece is a great target for tsunamis due to its closeness to the ocean, volcanoes, islands, and a fractured and shallow seabed. Greece is additionally vulnerable because of the frequency at which earthquakes occur in North Africa—a 2004 Algerian earthquake struck the southern coast of Greece and the island of Crete.
Coastal earthquakes have indeed been responsible for some of Chile’s most deadly earthquakes. An earthquake of magnitude 8.5 hit the coast in 1960, causing a tsunami. Residents attempted to evacuate on tiny boats, but the tsunami attacked within 10 minutes after the earthquake, leaving many without time to flee.
Apart from these top 5 countries that are affected by tsunamis are Italy, Russia, the Philippines, New Zealand, and Papua New Guinea.
