The 2004 Indian Ocean earthquake was massive in geographical and geological extent. An estimated 1,600 kilometres of fault floor slipped alongside the subduction zone the place the Indian Plate slid beneath the Burma Plate.
The sudden vertical rise of the seabed as a result of earthquake displaced huge volumes of water, ensuing within the tsunami that struck the coasts of the Indian Ocean creating havoc in 14 coastal international locations.

of TNT, twice the entire explosive power used throughout World War II. In many locations, the waves reached 2 kilometres inland.
Since the tsunami occurred in a big space geographically, it took from quarter-hour to seven hours to achieve the coast traces of the Indian Ocean. While Indonesian island of Sumatra was hit rapidly, Sri Lanka and the east coast of India have been hit 90 minutes later.

Scarcity of meals, clear water, and medicines together with the daunting process of reduction employees making an attempt to get provides into distant areas and islands prolonged the record of casualties.
The international locations which received affected by the tsunami additionally witnessed long-term environmental damages. Apart from lack of lives, Boxing Day tsunami broken ecosystems equivalent to mangroves, coral reefs, coastal wetlands, sand dunes and rock formations, biodiversity and groundwater.

How it affected India
Despite the time hole between the earthquake and the impression of the tsunami, not one of the impacted international locations may very well be warned of the upcoming catastrophe. There have been no tsunami warning techniques within the Indian Ocean to detect tsunamis or to warn the general public.
After the 2004 tsunami, India realised that it’s inclined to tsunamis too and the Indian Tsunami Early Warning System (ITEWS) at Indian National Centre for Ocean Information Services (INCOIS) was began in October 2007.
