Over a quarter-million people have been killed in tsunamis over the past century, according to the data compiled by Anadolu Agency.

According to the UN, which marks Nov. 5 as the World Tsunami Awareness Day, dozens of tsunamis — Often triggered by submarine earth slides and volcanic eruptions — have occurred in the past 100 years, killing hundreds of thousands.

In 2004, the western Indonesian coastline was devastated by a 9.1-magnitude earthquake and tsunami towering nine meters (29.5 feet). The tsunami was triggered by an earthquake that hit 14 countries, claiming 230,000 lives and causing damages of $10 billion.
