The 2004 Indian Ocean Tsunami and its Impact on Coastal Regions
Concept Map
The 2004 Indian Ocean Tsunami brought unprecedented destruction to coastal regions like Phang Nga, Krabi, and Phuket in Thailand, as well as India's southeastern shores and the Andaman and Nicobar Islands. The Maldives' coral atolls also faced the tsunami's wrath. The event highlighted the vulnerability of these areas to natural disasters and underscored the importance of disaster preparedness and the resilience of certain geographical features.

The 2004 Indian Ocean Tsunami: Devastation in Phang Nga, Thailand
On December 26, 2004, a massive undersea earthquake off the coast of Sumatra generated a series of devastating tsunamis that affected the Indian Ocean's rim countries. Phang Nga Province in Thailand, particularly the resort town of Khao Lak, was among the most severely impacted. The tsunami, captured by eyewitnesses, displayed the ocean's dramatic withdrawal and subsequent monstrous waves that engulfed coastal areas. In Khao Lak, the death toll was tragically high, with around 5,000 lives lost. The region's geography, including its coral reefs and shallow seabed, intensified the tsunami's force, leading to a record run-up height of 19.6 meters on Ko Phra Thong Island, the highest outside of Sumatra.Widespread Destruction in Krabi and Phuket, Thailand
The tsunami's wrath extended to Krabi Province, where the resort town of Ao Nang saw boats and debris swept away by the forceful waves. Phuket's western beaches, including the bustling Patong Beach, experienced significant damage as the tsunami surged ashore. Initially, the waves caused minor flooding, but they soon returned with much greater force, leading to extensive destruction and fatalities. Some coastal areas benefited from elevated roads that offered some protection, while the east coast of Phuket saw lower wave heights of around 2 meters. The Phi Phi Islands were also hard hit, with wave heights reaching 5.8 meters in the north bay of Phi Phi Don Island.Tsunami Impact on India's Coastal Regions
India's southeastern and southwestern shores felt the tsunami's impact approximately two hours after the earthquake. Tamil Nadu and Andhra Pradesh were among the worst-hit states, with some areas recording tsunami run-up heights of up to 5 meters. Chennai's Marina Beach and the city of Karaikal were particularly affected. In Kerala, the tsunami's effects were most pronounced in the southern districts, with the highest number of casualties in the Alappad panchayat of Kollam district. The extent of the tsunami's reach and its damage varied, with certain regions experiencing less severe effects due to existing seawalls and natural topographical features.The Andaman and Nicobar Islands' Proximity to the Epicenter
The Andaman and Nicobar Islands, situated near the epicenter of the earthquake, were among the first to be hit by the tsunami. Reports from South Andaman Island indicated that at least three large waves caused extensive flooding and destruction. The Nicobar Islands, particularly Little Andaman, faced waves as high as 12 meters, leading to catastrophic damage and significant loss of life. The geography of these islands played a role in the varying impact of the tsunami, with some areas shielded by their natural landscape, resulting in lower wave heights.The Maldives and the Tsunami's Effects on Coral Atolls
Despite being approximately 2,500 kilometers from the earthquake's epicenter, the Maldives experienced the tsunami's destructive power. The archipelago's coral atolls and deep oceanic channels influenced the tsunami's behavior, somewhat reducing its strength. The highest recorded wave in the Maldives reached 4 meters, with the most extensive flooding occurring on Male Island in the North Male Atoll. The timing of the tsunami's arrival during low tide also played a role in mitigating its impact. This event has since provided valuable insights into the resilience of coral atolls to tsunami events and has informed ongoing research in marine geology and disaster preparedness.
