Tsunami Warning System (MIS 750)

Recently, there have been many earthquake happen all around the world. Some scientist, relate the increase of natural disaster phenomenon with the increase of carbon dioxide (CO2) in the earth atmospheres as explained by the global warming crisis. Because there changes in the percentage of other gasses in our atmosphere, it effects the earth temperature, the air pressure, humidity and many more making the earth become unstable which lead to the natural disaster that occurs all around the world such as, typhoon, hurricane, earthquake and etc.

Earthquake is a natural disaster in which will lead to the lost many people. Earthquake that happen out far from the city or land which is in the middle of the ocean might not be directly affected us but the outcome of it may be disastrous. Earthquake with bigger rector scale can form a tsunami that can be dangerous and harmful to us. Other than earthquake that can form a tsunami, a volcanic impact, meteorite impact, landslide or explosion that happen in the large volume of body of water such as the ocean or lake.  

Countries, that are prone to be affected by tsunami such as Japan and American has this warning system that in general are called the Tsunami Warning System (TWS). Developed countries will surely have the advance warning system compared to the poorer country. But with the advancement of the internet, all people can receive the warning alert if there is any earthquake or tsunami is happening.

Tsunami can be disastrous as we have seen in 26th December 2006 that take millions of life and destroyed thousands of home and building. The biggest tsunami incident recently is the 11th March 2011 in Japan. As a human being, we cannot stop the natural disaster from happening but equip with a better technology, we can predict the incoming tsunami, the size, the speed, and anything related to the tsunami. With these, we can have an early system warning that can help reduce the damage and the life loss due to tsunami. The warning alert is for the people that lived near the shore line to evacuate the danger zone of tsunami before the impact, basically three to one hour prior the impact. TWS, not only warns people about the incoming tsunami, but TWS also helps government and non-government organization (NGO) prepared for the after impact of tsunami.

Below is the flow of how the Tsunami Warning System interacts with each component by transmitting data and communicating from sensory system under the ocean floor, buoy transmitter to the satellite and finally to the station.
