A tsunami, a series of giant waves, often starts deep within the ocean. Usually triggered by seismic activity such as an undersea earthquake, a tsunami races across the sea, building in size as it approaches land. Tsunamis are powerful and can cause enormous destruction. The 2004 Indian Ocean tsunami, for example, killed over 230,000 people in 14 countries. However, humans are resilient and can rebuild their communities after a tsunami. Scientists are also constantly working to improve tsunami prediction to help protect coastal communities.
