Devastated Asia - Tsunami Attack :: essays research papers

(Based on the declination 26th attack)What Are Tsunamis, and What Causes Them? Tsunamis are ocean waves produced by earthquakes or underwater landslides. The word is Japanese and means "harbor wave," because of the devastating effects these waves gull had on low-lying Japanese coastal communities. A tsunami is a serial of waves that can travel at speeds averaging 450 (and up to 600) milliliters per hour in the give ocean. As the waves mount the coast, their speed decreases and their amplitude increases. Tsunamis are most practically generated by earthquake-induced movement of the ocean floor. Landslides, volcanic eruptions, and even meteorites can in like manner generate a tsunami. Areas at greatest luck are slight than 25 feet above sea level and within one mile of the shoreline. From an initial tsunami generating source area, waves travel outward in all directions very much like the ripples caused by throwing a rock into a pond. As these waves approach coastal a reas, the time between successive wave crests varies from 5 to 90 minutes.Their Effecton livesMost deaths caused by a tsunami are because of drowning. Associated risks embroil flooding, contamination of drinking water, fires from ruptured tanks or gas lines, and the loss of vital residential district infrastructure.on hygieneContrary to popular belief that rapid sepulchre is essential to prevent outbreaks of disease, post-disaster, a report by the Pan American Health Organisation (PAHO) says dead bodies pose a negligible risk .on the infrastructureWith most people focusing their attention on the losses suffered by the fishing community, in the aftermath of the tsunami, Tamil Nadus (deprived of aid) coastal farmers have to come to terms with destroyed crops, damaged grease and devastated livelihoods.Scores of farmers in Tamil Nadu face an uncertain future as the water that engulfed their fields, washing away crops, has left the soil saline and uncultivable. Although the end of t he damage is yet to be fully assessed, officials say that a actual proportion of cultivable land has been contaminated by salt water.on tourismTourism constitutes a major sector of the Indian thriftiness and it leave be correct to say that it has been affected due to the tsunami tragedy.Tourists who were planning to go to the south eastern coastal regions have cancelled their bookings at the last few minutes. Travel agents have had to deal with these last-minutes cancellations and there will be an immediate impact on the travel industry for India.
