Similar stuff has been going on for decades. Developments on lands that are technically unsafe or unsound in the face of known natural hazards, even to the point of making the original situation even worse.<br />In a course I took back in the early 70s about natural hazards and why people still settle near them, living in San Francisco and knowing that earthquakes and the occasional or periodic big one entails making a decision. People choose to live in such areas for different reasons, even with the perception of impending disaster.<br />In the specific case of San Francisco, it was complicated further with the construction on lands reclaimed from the bay. Not only would the people living there be at ground zero for a major earthquake, their particular piece of ground zero would subduct into the water due to the vibrations accompanying the earthquake in a process called liquefaction in which unconsolidated "solid" material starts to act like a liquid and everything sinks.Anonymoushttps://www.blogger.com/profile/06015243895718744093noreply@blogger.comtag:blogger.com,1999:blog-4817488808342083958.post-84877950267994810312017-08-30T21:53:40.337-07:002017-08-30T21:53:40.337-07:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/06015243895718744093noreply@blogger.com
