A tsunami is a large sea wave caused by seismic activity under the sea, such as earthquakes or volcanic eruptions. When tectonic plates shift suddenly, they displace water and create huge waves that can reach heights of over 1 km and speeds of 500 mph. The 2004 Indian Ocean tsunami was one of the worst on record, caused by a 9.2 magnitude earthquake off the coast of Sumatra. It killed over 225,000 people across 8 countries and caused billions of dollars in damage. After such disasters, relief efforts like providing shelter, food and medical aid are crucial for rehabilitation.
