INDIAN OCEAN TSUNAMI
On December 26, 2004, one of the largest recorded earthquakes occurred on the continental shelf of the island of Sumatra in the east of the Indian Ocean. The tremor created a huge wave in all directions. It was like a circle of stones when you threw stones into a lake. In the open sea, the height of this wave did not exceed 1 meter, but when it reached the shore, the wave height exceeded 25 meters. When this tsunami hit the shores, it killed more than 200,000 people. EARTHQUAKE caused 3 TRILLION TONS of water in the seabed to be displaced.
It took 15 minutes for the tsunami to reach the coast of Sumatra. Thousands were caught unprepared. The giant wave hit Thailand and Sri Lanka two hours later and reached the coast of East Africa, about 8 hours later, west of the Indian Ocean. The wave along the seas along its path has also been observed on the Canadian and Mexican coasts, crossing the Pacific Ocean.
After the 2004 tsunami, a warning system was established in the Indian Ocean. In this system, there are devices that record the vibrations and pressure in the seabed. These devices send a warning signal to the satellites when the data indicates a tsunami hazard.
