Tsunamis
On December 26 of 2004 a big tsunami occurred, that is called, The Wave that Shook the World. This day 250,000 people died in twelve different countries and destroyed everything. This happened on a regular day and the tsunami happened because two plates were pushing against each other when one plate gave way to subduction.However while this happened, the top plate suddenly collapsed on the bottom plate, putting an enormous amount of pressure to the top of the ocean, making an underwater earthquake.
As soon as that happened, tsunami sensor buoys sent a signal to the warning center. When a buoy senses an earthquake, they send a message to a satellite to which the satellite sends the information to the warning center. The warning signal was sent to the Pacific Tsunami Warning Center in Hawaii.Usually the earthquake scientists are paged when an earthquake of a factor of 6 or larger occurs. They had 6 buoys in the Pacific Ocean, however there are none in the Indian Ocean. The scientists saw that the earthquake was shallow, it was 30 kilometers deep.
The tsunami destroyed many countries. It destroyed the Asian and African areas. Buildings were destroyed, Dead people were everywhere and there were not many survivors. The tsunami was huge, it destroyed everything in its path with no problem. After it was done, people thought they were safe but they were wrong and a bigger tsunami occurred after that. There are signs that you can tell whether or not a tsunami will occur or not.When you are at the beach and suddenly the water is sucked out and exposes the ocean floor for a mile away, there will be a tsunami. When this warning happens, people don't think about it. In fact, people go closer to see what's going on and that is their downfall. After the tsunami happened, the warning center decided to put 39 more buoys in order to prevent this kind of catastrophe from happening again.
