TSUNAMI DISASTER, WHAT IMPLICATION ON ECONOMIC SYSTEM IN THIS REGION? We view with awe a release of power on this scale. We know that this power is greater than that of our species — nature holds us in its hands. We may be able to mitigate some of the consequences; in some cases we may be able to give advance warning of the threat; but we are not in control; the tsunami has demonstrated this ancient truth. William Rees-Mogg INTRODUCTION 1.     On the morning of December 26, 2004 a magnitude 9.3 earthquake struck off the Northwest coast of the Indonesian island of Sumatra. The earthquake resulted from complex slip on the fault where the oceanic portion of the Indian Plate slides under Sumatra, part of the…show more content…

TSUNAMI – WHAT ARE THEY? 5.     Tsunamis are not wind-generated waves. Rather, they are shallow-water waves, with long periods (time between two sucessional waves) and wave lengths (distance between two sucessional waves). The wind-generated swell one sees at a California beach, for example, spawned by a storm out in the Pacific and rhythmically rolling in might have a period of about 10 seconds and a wave length of 150 m. A tsunami, on the other hand, can have a wavelength in excess of 100 kilometer and period on the order of one hour. As a result of their long wave lengths, tsunamis behave as shallow-water waves . A wave becomes a shallow-water wave when the ratio between the water depth and its wave length gets very small. Shallow-water waves move at a speed that is equal to the square root of the product of the acceleration of gravity and the water depth. In the Pacific Ocean, where the typical water depth is about 4,000 meter, a tsunami travels at about 200
