At 7:59 am local time on Sunday, 26 December 2004, an earthquake of Magnitude 9.1 occurred off the west coast of Sumatra, Indonesia (3.316°N, 95.854°E, depth 30km) (United States Geological Survey, 2015). It is the third largest earthquake in the world since 1900 (National Oceanic and Atmospheric Administration, 2015). It also resulted in serial other earthquake and a large Tsunami in South and Southeast Asia. There are not many casualties caused by the earthquake itself because the epicenter is uninhabited sea. However, a Tsunami followed by an earthquake of Magnitude 7.7 occurred off the coast Java in 2006 had attacked the unprotected coastal zone far away from hundreds and thousands kilometers. It caused 227,898 people dead or missing and nearly ten million refugees as well, which is the maximum number than any other Tsunami in history (National Oceanic and Atmospheric Administration, 2015). The energy released by the earthquake are equal to 23,000 atomic bombs (SMS Tsunami Warning, 2015). The Tsunami implicated not only Indonesia, but also Sri Lanka, Thailand, Bangladesh, India, Malaysia, Myanmar, …show more content…
Found the “Intersect Analysis” by using the “Search Tool” and added both the “Southern_Regencies” and “Contours” in the dialog box in order to get the “Southern_Regencies_Intersect” layer. Selected the “Table Contribution” of the “Southern_Regencies_Intersect” layer and created three fields called “Metric_area_output” and “Population_affected” and “Population_0_9_affected”. Then, used “Calculate Geometry” to calculate “Metric_area_output” and use “Field Calculation” to calculate “Population_affected” by entering Equation 3 and “Population_0_9_affected” by putting Equation 4 below and got the number. Finally, used “Statistics” to look the tables of each IDZs to find the number of affected
