Watch Mega Disasters Season 2 Episode 8 Online

An earthquake in New York City may seem like the plot of a bad movie, but a magnitude 5 quake occurred in 1884 and could happen again. Two faults run under Manhattan Island, including the 125th Street Fault where the landscape dips and the subway crosses on an open bridge. Since skyscrapers are designed to withstand windspeeds of 100 mph, most would survive sans windows; however, mid-sized masonry structures would collapse. As well, buildings (including smaller skyscrapers) built on landfill in Battery Park are subject to soil liquefaction, tipping over entirely in a major earthquake.
