The 2004 Indian Ocean earthquake occurred at 12:58 am UTC on December 26 with the epicentre off the west coast of Sumatra, Indonesia. The shock had a moment magnitude of 9.1–9.3.

The undersea mega-thrust earthquake was caused when the Indian Plate was subducted by the Burma Plate and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean.

It is the third-largest earthquake ever recorded on a seismograph and had the longest duration of faulting ever observed, between 8.3 and 10 minutes. It caused the entire planet to vibrate as much as 1 centimetre and triggered other earthquakes as far away as Alaska.

Areas affected include Indonesia, Sri Lanka, India, Thailand, Maldives, Malaysia, Madagascar, Somalia, Kenya, Tanzania, and South Africa.

Waves measured  15 to 30 metres, however, maximum run-up of 51 metres was observed at Lhoknga.
The tsunami left 230,000 to 280,000 dead and more missing.
