The 2004 off-Sumatra earthquake (Mw=9.0) was the largest subduction-zone earthquake in the world since the 1964 Alaska earthquake. The 2004 earthquake generated large tsunamis, which propagated across the Indian Ocean and caused the catastrophic disaster. Our international tsunami survey team investigated in the province of Nanggroe Aceh Darussalam, northern Indonesia, in order to clarify the magnitude of tsunami and distribution of tsunami deposits caused by this earthquake.
