Indian Ocean Tsunami

26th December 2004

Destructive Plate Margin along the west coast of Indonesia in the Indian Ocean.

Earthquake off the west coast of the island of Sumatra: 9.1 on the Richter Scale.

The plate being subducted into the mantle cracked and moved very quickly. This caused a lot of water to be displaced = a tsunami with waves upto 30m high.

One of the MOST DESTRUCTIVE natural disasters EVER

Affected most of the countries bordering the Indian Ocean; Sri Lanka, Thailand, India and Indonesia.

The effects of the tsunami were so bad because THERE WAS NO EARLY WARNING SYSTEM!
