On December 26, 2004, a massive underwater earthquake off the coast of Indonesia's Sumatra Island rattled the Earth in its orbit. The quake measuring 9.0 on the Richter scale is the largest one since 1964. Dozens of aftershocks with magnitudes of 5.0 or higher occurred in the following days. But the most powerful and destructive aftermath of this devastating earthquake is the tsunami that it caused. The death toll reached higher than 225,000, and many communities suffered devastating property damage
The devastation of this tsunami overshadowed the devastation of any other tsunami we've seen in recent history, but scientifically, the course of events followed the same basic sequence of a typical tsunami. In this paper, we'll look at what causes tsunamis, the physics that drives them and the effects of a tsunami strike. We will also examine scientists' worldwide efforts to monitor and predict tsunamis with the help of a TSUNAMI WARNING SYSTEM in order to avoid disasters like the one that occurred in the final days of 2004. This paper also focuses on an improved version of the TSUNAMI WARNING SYSTEM called the DART (DEEP OCEAN ASSESMENT AND REPORTING OF TSUNAMIS).
