15 Years Hence, Catastrophic Indian Ocean Tsunami Still Haunts Us!

On the 15th anniversary of one of the world’s most deadly disasters, communities across Asia commemorated the victims of the Indian Ocean tsunami. Today, many of the communities have recovered, though painful memories and some ruined structures remain in place. Across Asia today, memorials were held in remembrance of the thousands of victims.

Memorials Commemorating the Victims

15 years after 2004 Indian Ocean Tsunami, memorials were scheduled in the Indonesian province of Aceh, where entire villages were flattened and more than 125,000 people perished in the giant waves. Since then, the area has been largely rebuilt, with some 25,600 residential, commercial, government and school buildings constructed inside a high-risk zone that had suffered virtually total devastation in 2004.


In Thailand, where more than 5,300 people were killed, including tourists visiting resort islands in the Andaman Sea, officials held a memorial ceremony and called for more awareness and preparedness for disasters.


In India, where more than 10,000 people died in the tsunami, survivors also were to hold memorial ceremonies. More than 35,000 people died in Sri Lanka. An interfaith service for Muslim, Christian and Buddhist victims was also scheduled.


Even after 15 years, families of the victims still shudder on the memory of the disaster. They have been worshiping the sea on December 26 every year since. Anointed with flowers, milk, and pleading for the sea to be at peace with humanity forever.

Indian Ocean Tsunami, 2004

It was the morning of December 26, 2004, when an earthquake of a magnitude-9.2 disrupted the ocean floor off Indonesia, sending the most devastating tsunami with waves as high as 17.4 meters (57ft.) across the Indian Ocean. More than 230,000 people were killed in 13 countries, a million others were uprooted and entire coastlines across the Indian Ocean were destroyed.

Witnesses in the Indonesian city of Banda Aceh, reported five to six minutes of violent shaking and a few collapsed buildings during the main quake (the aftershocks caused more damage with subsequent, repeated shaking). It was the only city to report damage directly from the earthquake; most of the day’s damage would come from the tsunami waves generated by the quake.

The hypocenter of the earthquake was 10 kilometers below the surface and about 250 kilometers offshore of Sumatra, with a registered magnitude of 9.1-9.3 on the Richter scale. The earthquake was caused by the collision between the Burma Plate and the Indian Plate in the seabed. The US Geological Survey concluded that the tsunami generated 23,000 times more energy than the US’s atomic bomb on Hiroshima.

The Aftermath

The 2004 Sumatra-Andaman quake burst hundreds of kilometers along the Sunda trench with a maximum displacement of 20 meters. The initial earthquake was the longest ever recorded, lasting between 8 and 10 minutes, and created the biggest gash in the Earth’s seabed ever observed – nearly 800 miles.

Due to the distances traveled by the displaced water, the tsunami hit land anywhere between 15 minutes and seven hours after the earthquake. Parts of South Africa, over 5,000 miles away, suffered a 5 ft. high tide some 16 hours later.

The UN initially feared that the death toll could double due to the lack of food and clean water and the spread of disease in the wake of the tsunami. But, a massive international campaign for humanitarian aid began in the immediate aftermath.

Six months after the disaster about £7 billion had been pledged from around the world, with UK citizens donating roughly £330 million – a much larger figure than the British government.

Tsunamis being relatively infrequent in the Indian Ocean, no warning system was in place at the time. By June 2006, the Indian Tsunami Warning System – 25 seismographic stations relaying information to 26 national tsunami centers – was made operational.

Despite this, the effects of the disaster continue to be felt. While local economies are on the road to recovery, the environmental damage and the emotional impact on those who survived will remain harder to quantify.
