Twenty-sixth December 2004 was an unforgettable day for Indonesia, especially the Acehnese. At that time, a powerful underwater earthquake occurred and triggered a tsunami. The 9.1 magnitude earthquake became a very strong megathrust earthquake, occurring where heavy oceanic plates slip beneath the lighter continental plates. The earthquake occurred in the morning, when many people had started activities. After the earthquake rocked, the tsunami began to roll about 100 kilometers west of the Sumatra coast at 07.59 WIB.
