It has been 10 years since the Indian Ocean tsunami and earthquake devastated parts of Indonesia Sri Lanka, India and Thailand.
The disaster was the world’s deadliest tsunami, with over 230,000 people killed and half a million injured by the waves that struck the low-lying coast.
The 2004 Indian Ocean tsunami occurred when the Indian Plate subducted below the Burma Plate and triggered a 9.1 magnitude earthquake, Metro reported.
The tsunami affected 14 countries from Indonesia and Thailand to Somalia and South Africa, killing about 230,000 people and injuring half a million, the IBTimes reported.
In the aftermath, more than $15 billion in humanitarian aid was raised internationally to help affected areas to rebuild.
The Indian Ocean Tsunami Warning System was constructed and put to use in 2006. Seafloor pressure sensors record earthquakes and pass the information to a surface buoy, which transmits the data to a satellite and eventually to control centres on the ground.
Ten deep-ocean assessment and reporting buoys are deployed in the Indian Ocean. Regional Tsunami Service Providers have been set up in Australia, India and Indonesia to operate as tsunami advisories for the Indian Ocean.
