In this case, the Indian Ocean tsunami of 2004 was generated by an earthquake. On December 26, 2004, a massive undersea earthquake occurred off the coast of Sumatra, Indonesia. This earthquake, known as the Sumatra-Andaman earthquake, registered a magnitude of 9.1–9.3 on the Richter scale. It caused the seafloor to uplift, displacing a massive amount of water and triggering a series of destructive tsunami waves that propagated across the Indian Ocean. These tsunami waves eventually reached the coasts of several countries, resulting in one of the deadliest natural disasters in history.
