..a few interesting facts.....
A tsunami is not just one big wave, but a series of waves called a “wave train.” The time period between waves is called the “wave period” and can be between a few minutes and two hours. The first wave is usually not the strongest, and later waves, such as the fifth or sixth, may be significantly larger The Indonesia 9.0 earthquake in 2004 released more energy than all the earthquakes on the planet in the last 25 years combined. A segment of seafloor the size of the state of California moved upward and seaward by more than 30 feet, displacing huge amounts of water While no one has witnessed a tsunami caused by a meteorite, many scientists think that a meteorite may have created a tsunami that wiped out life on Earth more than 3.5 billion years ago |
