TSUNAMI WARNING SYSTEM TO MOBILE PHONES
The term tsunami originates from Japanese and means “harbour wave” .It is a series of waves when a body of water, such as an ocean is rapidly displaced on a massive scale. Tsunamis cannot be prevented or precisely predicted, but there are many systems being developed to warn and save the people of regions with a high risk of tsunamis before the wave reaches land.
Our paper focusses on the TSUNAMI WARNING SYSTEM TO MOBILE.
This system warns subscribers of an impending tsunami, wherever they are, via a mobile text message. The tsunami alarm system picks up seismic signals from global stations and consolidates the information. If there is a danger of a tsunami, an alarm is sent out to subscribers via an SMS. The Global System for Mobile Communications (GSM) is the most popular standard used here for making calls such as text messaging. The ubiquity of the GSM standard makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. The paper discusses about the reception and consolidation of the relevant information of tsunami by the satellite and the way in which this information is transmitted by the satellite and received by the mobile .This system is an efficient and a promising attempt to minimize destructions and save the lives of millions of people around the world .
WHAT IS A TSUNAMI ?
The term tsunami comes from the Japanese language Destructive Tsunami meaning harbour ("tsu") and wave ("nami"). The term was created by fishermen who returned to port to find the area surrounding their harbour devastated, although they had not been aware of any wave in the open water. A tsunami is a series of waves when a body of water, such as an ocean is rapidly displaced on a massive scale. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, and large meteorite impacts all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating. CAUSES
Tsunamis can be generated when the sea floor abruptly Generation of a tsunami deforms and vertically displaces the overlying water. Such large vertical movements of the Earth’s crust can occur at plate boundaries. Subduction earthquakes are particularly effective in generating tsunamis. As an Oceanic Plate is subducted beneath a Continental Plate, it sometimes brings down the lip of the Continental with it. Eventually, too much stress is put on the lip and it snaps back, sending shockwaves through the Earth’s crust, causing a tremor under the sea, known as an Undersea Earthquake. Sub-marine landslides as well as collapses of volcanic edifices may also disturb the overlying water column as sediment and rocks slide downslope and are redistributed across the sea floor. Similarly, a violent submarine volcanic eruption can uplift the water column and form a tsunami.
Often referred to as "tidal waves", a tsunami does not look like the popular impression of "a normal wave only much bigger". Instead it looks rather like an endlessly onrushing tide which forces its way around and through any obstacle. Most of the...
