In recent years, the number of deaths caused by hurricanes has decreased, but the cost of hurricane damage has increased. How would you explain this?
What will be the ideal response?
ANSWER: With the aid of ship reports, satellites, radar, buoys, and reconnaissance aircraft, the location and intensity of tropical cyclones are pinpointed and their movements carefully monitored. Once a tropical depression forms, its motion and strength are predicted out to the following five days by the National Hurricane Center in Miami, Florida, or by the Central Pacific Hurricane Center in Honolulu, Hawaii. These forecasts are then updated every six hours (or more often if a hurricane is nearing shore). These forecasts are invaluable with regard to issuing warnings and saving human life. However, despite the available technology today, coastal areas are so much more densely populated, and the world’s population is ever increasing, resulting in ever increasing damage costs as well.?
