13 years since tsunami brought its havoc on 14 countries including Indonesia, India

Kolkata, Dec 26: It has been 13 years since the tsunami which originated in the Indian 

Ocean, wreaked havoc on 14 countries, including Indonesia, India, Sri Lanka and others.
On this day in 2004, the tsunami struck south-east Asia killed over 230,000 people in 14 different countries, mostly in Indonesia.
The earthquake and resulting tsunami in the Indian Ocean had a devastating effect on 
India.
According to the Central government, almost 11,000 people died in the tsunami and over 5,000 are missing and feared dead.
Minutes after the earthquake the waves hit Andaman and Nicobar islands. In mainland India, Tamil Nadu and Andhra were worst affected. Chennai was one of the most major cities to be affected by the tsunami.
West Bengal Chief Minister Mamata Banerjee today remembered the hundreds of thousands who died in the incident.
“On this day in 2004, the tsunami had struck south-east Asia. Solemnly remembering the hundreds of thousands who died, including thousands in India, and those numerous whose lives were changed forever,” Ms Banerjee posted on her social networking page.
The tsunami was a result of a megathrust 9.1 earthquake with the epicentre off the west coast of Sumatra, Indonesia. This was one of the highest rating the Richter Scale had ever shown in recent history. Waves of up to 15 meter hit the coastlines of Thailand, India, Sri Lanka and Sumatra.
On December 26, 2004 morning walkers and fishermen residing along the eastern coast of India observed a strange phenomenon of the sea receding few hundred metres inside exposing parts of the coastal shelf. What they were observing was a precursor to the incoming gigantic tsunami waves generated due to a M 9.3 Great undersea earthquake off the coast of Banda Aceh, northern Sumatra.
This earthquake occurred along a thrust fault in the subduction zone where the Indian tectonic plate is going below the overriding Burmese plate. As a result, the ocean floor broke and there was a vertical displacement of about 15 to 20 meters along the fault causing large scale displacement of water and thus, generating tsunami waves. UNI
