2004 Indian Ocean earthquake

The 2004 Indian Ocean earthquake was a massive undersea earthquake that occurred on December 26, near Sumatra, Indonesia. It measured a magnitude of about 9.1-9.3, making it one of the strongest in history. The quake caused the seafloor to shift sharply, displacing enormous amounts of water and triggering a devastating tsunami. The resulting waves traveled across the Indian Ocean, hitting multiple countries including Indonesia, Sri Lanka, India, and Thailand. Over 230,000 people died, and millions were displaced and affected, making it one of the deadliest natural disasters in modern history.
