On 28 March 2005, the island was again hit by the 2005 Nias–Simeulue earthquake, initially presumed to be an aftershock of the 2004 quake, but now regarded as the second most powerful earthquake ever recorded in Indonesia and among the top 10 most powerful recorded worldwide since 1900. At least 800 people were reported dead, with the possibility of more than 2,000 casualties. Hundreds of buildings were toppled and many thousands of people were made homeless. In 2007, almost two years after the earthquake, there were still tens of thousands of internally displaced persons living in camps throughout Nias.
