Few may realize it, but only 13 miles from Pelham -- far beneath 125th Street in Manhattan -- lies the so-called "125th Street Fault Line." While it is nothing like major fault lines such as the "San Andreas Fault" on the west coast of the United States, the 125th Street Fault Line is still a concern to experts who recognize that population growth in the region since the late 19th century have increased the risks of substantial damage from major earthquakes.
