After two earthquakes in four days, is New York City ready for a big quake and does it actually need to be
0:08
In the span of just a few days, the Big Apple shook from a 3.0 and 2.7 magnitude earthquake
0:15
Both caused minimal damage and no serious injuries. A recent report from the city showed a magnitude 5 earthquake would cause billions of dollars in damage
0:25
However, is that likely to happen? If you are talking about large earthquakes, you need plate motion and you need to be close to the boundary of two plates that are moving relative to each other
0:39
We are just not living in that place, although we are at the edge of the continent, but it's a passive boundary

Both of this week's earthquakes came along the Ramapo fault line, which formed 200 million years ago
0:55
It's in the middle of a stable tectonic plate, unlike the famous San Andreas Fault, which is the boundary of two different tectonic plates
1:03
San Andreas moves constantly whereas Ramapo is mostly still and movement is what needed for big quakes If you look at the GPS motion along St Andrews Fort it is moving quickly It is moving relatively in large amount every year relative to the other side of the fort
1:22
But it's just not happening here in our place. Lower odds doesn't mean it's impossible
1:27
The city's report showed a 5.2 magnitude earthquake hit the city back in 1884
1:32
If an earthquake like magnitude 5 hit very close to Manhattan, people will feel much stronger shake and there will be more disruption to the civic system like a running subway train can fill that earthquake and will have to shut down a large part of the city because of the shake
1:53
So I can imagine a lot of economic impact to this region if magnitude of five earthquakes happens
2:04
Shen says preparedness is always a good thing, and that starts with teaching people what to do if a quake hits
