New York City may appear to be an unlikely place for a major earthquake, but according to history, we’re past due for a serious shake. Seismologists at Columbia University’s Lamont-Doherty Earth Observatory say that about once every 100 years, an earthquake of at least a magnitude of 5.0 rocks the Big Apple. The last one was a 5.3 tremor that hit in 1884 — no one was killed, but buildings were damaged.
Any tremor above a 6.0 magnitude can be catastrophic, but it is extremely unlikely that New York would ever experience a quake like the recent 8.9 earthquake in Japan. A study by the Earth Observatory found that a 6.0 quake hits the area about every 670 years, and a 7.0 magnitude hits about every 3,400 years.
John Armbruster, a seismologist at the Earth Observatory, said that if a 5.0 magnitude quake struck New York today, it would result in hundreds of millions, possibly billions of dollars in damages
. The city’s skyscrapers would not collapse, but older brick buildings and chimneys would topple, likely resulting in casualities.
The Earth Observatory is expanding its studies of potential earthquake damage to the city. They currently have six seismometers at different landmarks throughout the five boroughs, and this summer, they plan to place one at the arch in Washington Square Park and another in Bryant Park.
Won-Young Kim, who works alongside Armbuster, says his biggest concern is that we can’t predict when an earthquake might hit. “It can happen anytime soon,” Kim told the Metro. If it happened tomorrow, he added, “I would not be surprised. We can expect it any minute, we just don’t know when and where.”
Armbuster voiced similar concerns to the Daily News
. “Will there be one in my lifetime or your lifetime? I don’t know,” he said. “But this is the longest period we’ve gone without one.”
