A series o massive tsunami waves grew up tae 30 m (100 ft) heich ance heidin inland, efter bein creatit bi the underwater seismic activity offshore. Communities alang the surroondin coasts o the Indian Ocean war severely affected, an the tsunamis killed an estimatit 227,898 fowk in 14 countries, makin it ane o the deadliest naitural disasters in recorded history. The direct results caused major disruptions tae livin conditions an commerce in coastal provinces o surroondit countries, includin Aceh, Indonesia, Sri Lanka, Tamil Nadu, Indie an Khao Lak, Thailand. Banda Aceh reportit the lairgest nummer o daiths.

The yirdquauk wis the third-lairgest ever recorded an haed the langest duration o faulting ever observed; atween aicht an ten minutes. It caused the planet tae vibrate as much as 10 mm (0.4 in), an remotely triggered earthquakes as far away as Alaska forby. Its epicentre wis atween Simeulue an mainland Sumatra. The plight o the affected fowk an countries prompted a warldwide humanitarian response, wi donations totalling mair nor US$14 billion.
