A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, landslides,underwater earthquakes, large meteoroid or asteroid impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating.
A tsunami can be generated when the plate boundaries abruptly deform and vertically displace the overlying water. Such large vertical movements of the Earth’s crust can occur at plate boundaries. Subduction earthquakes are particularly effective in generating tsunami.
Date
December 26, 2004
Magnitude
9.3 Mw
Depth
30 km (19 mi)
With a magnitude of between 9.1 and 9.3, it is the second largest earthquake ever recorded on a seismograph. This earthquake had the longest duration of faulting ever observed, between 8.3 and 10 minutes. It caused the entire planet to vibrate as much as 1 cm (0.5 inches) and triggered other earthquakes as far away as Alaska.
Seismology is the study of the Earthquakes. Seismograph is the graphical representation of the seismic wave. The disaster is known by the scientific community as the Great Sumatra-Andaman earthquake and is also known as the Asian Tsunami and the Boxing Day Tsunami.
It has been reported that severe damage has been inflicted on ecosystems such as mangroves, coral reefs, forests, coastal wetlands, vegetationand dunes and rock formations, animal and plant biodiversity and groundwater. In addition, the spread of solid and liquid waste and industrial chemicals, water pollution and the destruction of sewage collectors and treatment plants threaten the environment even further, in untold ways. The environmental impact will take a long time and significant resources to assess
Ecosystem is the place where the lives survive. Mangroves are a kind of forests where the river water and the Sea water mixes up. Sewage is the term used to denote the Domestic waste water.
The importance in reminding this day is for the prevention of future. We have seen the effects of the Tsunami, and we have lost a number of lives surrounding us. this is an alarm that nature has the power to distruct anything. We have to preserve the nature, atleast not to destroy the nature.
I sincerely convey my condolence to those who have lost their parents, children, relatives and friends. Let us pray for all and plan to prevent the tsunami.
The term tsunami comes from the Japanese words meaning harbor ("tsu") and wave ("nami"). [a. Jap. tsunami, tunami, f. tsu harbour + nami waves. - Oxford English Dictionary].
