The 2004 Indian Ocean Earthquake and Tsunami.
The year 2004 sadly marked the deadliest natural disaster of the 21st century. In this episode, we take a look at “The 2004 Indian Ocean Earthquake and Tsunami," also known as the “Boxing Day Tsunami.”.
On the morning of December 26, 2004, at 7:59 AM, a powerful undersea megathrust earthquake struck the west coast of northern Sumatra, Indonesia. Its epicenter was between Simeulue and mainland Sumatra. The earthquake was caused by a 1,600-kilometer rupture along the fault, between the Burma Plate and the Indian Plate. In some areas, the earthquake reached a Mercalli intensity of IX, which is considered to be violent. On the Richter scale, it measured between 9.1 and 9.3, making it one of the most intense earthquakes ever recorded.

Initially, the waves developed away from the epicenter and traveled over the Indian Ocean at speeds reaching up to 800 kilometers per hour. Some waves, over 100 feet high, traveled hundreds of kilometers before crashing onto unsuspecting coastal towns.

Within minutes, the tsunami reached the shores of northern Sumatra, catching local communities completely off guard. Within hours of the earthquake, enormous waves smashed the beaches in 14 countries. Tsunami waves impacted shores in Indonesia, Sri Lanka, India, Thailand, the Maldives, and as far away as Somalia, on Africa's east coast.

The material and economic losses were very substantial. Many infrastructures along the coastline, including buildings, roads, bridges, and ports, were severely damaged. Thousands of homes were destroyed or seriously inhabitable, leaving significant populations homeless or without shelter. The tsunami caused significant economic losses, particularly in areas such as tourism and fishing. Many coastal businesses were severely damaged or simply lost forever.

Unfortunately, the human toll of the 2004 Indian Ocean tsunami was staggering. Estimates suggested that between 230 000 and 280 000 people perished, 125 000 were injured, 45 000 went missing, and 1.7 million were evacuated from their homes. Indonesia suffered the most loss of human life, with 168 000, followed by Sri Lanka with 35 000, India with 16 000, and Thailand with over 8 000 victims. Many people, and entire towns, struggled to deal with the loss of loved ones, pets, homes, and income.

The primary focus of humanitarian and government agencies was to provide sanitation facilities and clean drinking water in order to prevent the spread of diseases like cholera, diphtheria, dysentery, typhoid, and hepatitis A and B. More than 1.3 million individuals who were devastated by the tsunami received food from the World Food Program. Nations from all around the world contributed nearly 14 billion US dollars to the relief and restoration efforts.

The aftermath of the 2004 Indian Ocean tsunami necessitated extensive rebuilding efforts. Governments, humanitarian agencies, and non-governmental groups worked together to rebuild infrastructure, restore essential services, and assist affected people in re-establishing their sense of normality. As a major component of the recovery effort, 140,000 houses were built.

The 2004 Boxing Day tsunami left an indelible mark on the affected nations and the global community. The lack of a coordinated tsunami warning system in the Indian Ocean contributed to the high death toll. In response to this tragedy, the Indian Ocean Tsunami Warning System was established to improve early warning capabilities in the region. The tragedy also raised awareness of nations' interconnectivity in the face of natural disasters, developing a sense of collective responsibility for humanity's well-being. Lessons from the catastrophe highlighted the significance of early warning systems and better disaster preparedness in susceptible areas.
