The 2004 Bali tsunami was larger in scale, with a magnitude of 9.1-9.3, triggered by an undersea earthquake off the coast of Sumatra. The 2009 Samoan tsunami was caused by an earthquake off the coast of Samoa and American Samoa with a magnitude of 8.1, resulting in significant damage and loss of life but was not as widespread as the 2004 tsunami.
The Samoan tsunami was primarily caused by the interaction of the Pacific Plate and the Indo-Australian Plate. The movement and subduction of these tectonic plates along the Tonga Trench generated significant seismic activity, leading to the tsunami. This region is known for its complex tectonic activity, which contributes to the occurrence of earthquakes and tsunamis.
The Samoan tsunami, which struck in September 2009, caused significant damage to coastal villages in Samoa and American Samoa. Numerous homes were destroyed or severely damaged, along with infrastructure such as roads and schools. The tsunami also impacted local businesses and resulted in loss of life, with hundreds of injuries reported. Recovery efforts were extensive, focusing on rebuilding and providing aid to affected communities.
