# Tsunami# These are enormous ocean/sea tides that are caused not just due to the Gravity but due to the deep water phenomena such as Underwater Volcanic Eruptions, Earthquakes of Seabed and Underwater landslides etc. Since it moves the water from bottom of the ocean, it is hardly obvious on deeper sea surface but when it reaches the coastline, the energy (that was due to the speed of deepwater movement around 500mph) gets dissipated by means of very high tides ranging upto 100s of metres at coastline causing severe damages to the mankind. 2004 Indian Ocean Tsunami holds the highest number of death toll of around 200K. Though Tsunami prone Japan developed few measures like Sea walls and sea water irrigation, 2011 Fukushima (?) Tsunami hit it's nuclear power plant causing dangerous alert. Since it can't be effectively controlled, it is advised to run away from coastline to higher lands to save lives. Contemporary technologies made it feasible to track deepwater seismograph and to communicate the possibilities of Tsunami to the impactable areas for quicker relocation steps.
