What Do You Think? 

       Because of the earthquake threats from the San Andreas fault, the city of San Francisco has rigorous building codes requiring that buildings be designed to withstand earthquakes. On the other side of the United States, however, the building codes are less rigorous. An earthquake in Virginia in August 2011 was felt along most of the east coast, prompting questions about whether existing building codes should be changed to meet the more rigorous San Francisco standards. But meeting the San Francisco standards makes construction a lot more expensive in San Francisco than it is in New York. Imagine you had to make a recommendation to the New York City Council about whether it should or should not adopt San Francisco building codes. Using what you’ve learned in this chapter, explain what your recommendation would be, and why.
