EXERCISE 14.12 Date What Do You Think Half of the population of the United State

Question

EXERCISE 14.12 Date What Do You Think Half of the population of the United States lives within 50 miles (80 km) of a shoreline. Disasters caused by recent tsunamis, hurricanes, and typhoons are making insurance companies reexamine risks and reevaluate premiums for insurance along shorelinesr consider if they should even offer insurance in some areas. They rely on geolo- gists' expertise, and you have been contacted by a company for your advice about whether there should be different policies and/or rates for the east and sulf coasts of North America as compared with the west coast. Your job is to outline the factors that control potential damage to coastal properties in these two regions. Questions to consider Do the regions have the same risk of damage by tsunamis and hurricanes? What factors determine the amount of potential damage in each of the regions? How would continued global climate change affect risk? How far inland would a 5-foot sea-level rise shift the shoreline? A 25-foot rise? To help, six shoreline profiles have been provided, each -5 miles long from either the Gulf of Mex- ico, or the Pacific or Atlantic coasts of the United States. On a separate sheet of paper, provide your report and recommendations for each coast. MT CT IA NE DE MD CO VA KY TN NM LA TX St. Auguatine

Explanation / Answer

If we'll see the shoreline of Oregon or California which lies on west coast of America we can say that the effect of the Tsunamis, hurricanes and typhoons and hence west coast cities face high risk of damage then east coast cities.

The factors that determine the amount of damage are:

With rise in global; temperature the risk of damages caused due to tsunamis, hurricanes and typhoons increses as more and more water will move towards landwards side thus causing damage to life and property.

Shifting of shore line will depends upon the slope of the terrestial part as high slope areas will be less effected as compared to low slope areas. Thus quantification of shifting will require slope of the area.
