Tsunami are powerful waves created by earthquakes, volcanic eruptions, or landslides that displace large volumes of water. They can reach heights over 30 meters and speeds over 700 km/hr, destroying everything in their path. The devastating 2004 Indian Ocean tsunami killed over 118,000 people across several countries, displaced millions, and caused widespread damage to infrastructure and the environment. Relief efforts provided temporary housing, food, water and medical aid to victims, but recovery is a long process and many remain in need of support years later.
