Tsunami warning system finally ready, after 8 years national December 25, Before monstrous waves hit Thai shores and killed over 8, people in six provinces along the southern coast, no one knew the tsunami was coming. All that will change with the early alert system and instruments installed by the National Disaster Warning Centre NDWC along the Andaman coast over the past eight years, backed by necessary regulations. Now, ample time for evacuation is assured with streamlined regulations, in a bid to save lives.

Several countries all around the world are being affected by this type of natural disaster and even though usually small tsunamis do not cause much damage, the giant waves are a threat.
A tsunami while reaching the shore full of people. As tsunamis are a natural disaster, we cannot prevent them but we can use early warning systems and community preparedness to minimize the effects and destruction. A Tsunami Warning System TWS is a system which is supposed to detect the tsunami and send out warnings to places that are in danger to prevent the loss of many human lives as well as loss of property.
The TWS has a tsunami detecting network of sensors and an alarming system which provides time to evacuate the coastal areas and other areas that are in risk of being hit by the wave.
However, this system is unable to predict if the earthquake generated a significant tsunami and this way there are more false alarms than actual verified warnings.
When the sensors detect an earthquake, they automatically send out signals and after observing the sea level height with shore-based tide gauges the existence of a tsunami is verified. A diagram of how a tsunami is triggered by an earthquake.
In order to do this there is a need for a tsunami early warning system. The map they managed to create was emerged to show all threat and it was the first of its kind in the USA.
It appoints receptive areas that are in danger of being flooded by a tsunami as well as areas that are exposed to seismic activity and landslips. Presently NOAA polishes up a network of deep sea signaling stations which will pick up a tsunami signals and will report about them immediately.
The tsunami warning system consists of a network of seismographs that send the results of measurements as soon as possible to the warning center. Forthcoming signals are analyzed incessantly, if an earthquake takes a place, the program defines its localization the geographic coordinates, its depthits magnitude amount of released energy and initial parameters generated by the tsunami.
If the energy of the potential tsunami surpasses a certain threshold, further modulations are made. The time for the tsunami to reach the closest sections of the coast is predicted and the height of the wave when reaching the shore is predicted.
If this height exceeds over the conceded safe height of the waves, the program automatically sends alerts and warnings to proper services in a certain region which provide the information of the predicted time and height of the tsunami until it reaches a certain place on the coastline.
Despite all these technological developments even the most reliable warning system will not be successful without the effective reaction from the citizens.
Those people must especially beware of earthquakes that could possibly generate a tsunami and in case of an emergency be able to quickly evacuate to higher located areas. The coastal communities should own maps of potential floods in order to previously direct and guideline escape route.
The warning system is made up of automatic stations on the surface of the water as well as deep-sea stations placed on the ocean floor which measure the pressure.
The level of the ocean water is gauged with the accuracy of 5 cm. The data from the GEOS satellite is supplied to the warning center and later on automatically analyzed. In case of exceeding over the level of the acceptable standards, the potential risk of danger is announced to convenient services.
The DART system has a purpose of decreasing the number of victims, minimizing the loss of property and destruction, as well as eliminating false alarms.
The informing action of how to behave during and after an earthquake and what to do when there is a tsunami wave approaching is led mainly in Japan.Natural Disasters and Prevention essaysWe are at a time where our society is able to bring the full force of scientific and technological advances to reduce the number of human tragedy and economic losses due to natural disasters.
Although, we must take an integrated and diverse approach to disast.
Warning Systems and Prevention Techniques of Tsunamis Essay Sample Published by admin on April 12, Tsunamis are series of ocean moving ridges caused by . A tsunami warning system (TWS) is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage to property.
It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas.
Warning Systems and Prevention Techniques of Tsunamis Essay Tsunamis are series of ocean waves caused by underwater seismic activity or volcanic activity. Several countries all around the world are being affected by this type of natural disaster and even though usually small tsunamis do not cause much damage, the giant waves are a threat.
The Boxing Day tsunami in South East Asia alone killed over 23, people and caused a humanitarian crisis on an almost unprecedented scale. It is impossible to prevent tsunamis from happening, as they are caused by earthquakes or volcanic eruptions under the water, both unpreventable natural disasters.
In India, the Department of Ocean Development in association with Department of Science and Technology (DST), Department of Space (DOS) and CSIR Laboratories, is setting up an Early Warning System for Tsunami and Storm Surges in the Indian Ocean.
