Now NYC Is Hit With An Earthquake!

[MostBoringManInTheWorld]

NYC was just hit with a rare earthquake.

When it rains, it pours. It was 2.3 on the earthquake scale.

It was centered near Sleepy Hollow.

Gee, what else can go wrong, it is as if this were an omen for events there.

Maybe the earth will swallow the city next?

Rare magnitude 2.3 earthquake rattles New York City suburbs

Westchester County reported shaking from a magnitude 2.3 earthquake on Tuesday morning.

Because earthquakes and sinkholes don't happen anywhere else.

Genius.

 

[MostBoringManInTheWorld]

Well, apparently it is noticeable when you never get earthquakes, but if you are going to get one, better 2.3 than 7.3.

If I'm not mistaken, New York City lies over a fault line.

So does New Jersey, I think.

The problem is, because very few earthquakes have happened in that area, the pressure building up over time will be so great that when the Big One finally happens, it will be utter and mass devastation unlike anything ever seen before. And last I heard, New York City skyscrapers are not designed to withstand earthquakes.

Then again, I'm not a geologist.

Yeah, it lies over the Ramapo Fault system, which is a right lateral, strike slip fault which originates in Pennsylvania and terminates in the NYC area.

200 million years or so ago, it was a thrust fault at the edge of a plate boundary, and quite active.

Now it is only associated with intraplate seismic activity, mush of which involves isostatic rebound of the plate from the last ice age.

It is not particularly dangerous. I think the max theoretical magnitude is a 6. The highest recorded is a 5.2 to a 5.5...I don't remember the actual reading, but it's in that range.

I really doubt anyone even felt it,

Well, the article said that people felt the shaking. Feeling an earthquake is perhaps more about the frequency of the event as it is about the amplitude which does the damage.

Possibly yes I suppose. In WA, and other parts of the west we have those all the time and rarely notice anything. In fact just this morning there was a 2.9 near Olympia just before 4am. Haven't heard much about it yet, but could be most people were still sleeping IDK.

Usually here it's not a big deal unless 3 or higher and/or multiple quakes in a short period of time. Like the swarms at Mt Rainier (last year I think?) that was something like over a hundred small quakes in a matter of days. Although many of those were under a 2, IIRC

Another factor of quakes and possibly feeling one, is the type of quake that results in either an up/down, side to side or rolling motion.

So tiny you can't even feel it unless you are particularly sensitive.

Small Earthquakes are felt over larger areas on the East Coast due to the nature of the bedrock in the area.

That being said, usually it takes a 3.0 or so to be felt regionally.

And yes, they do feel like trucks going by the house over rough roads.

The usual response to an East Coast earthquake is "Is that a truck, oh wait, is that an earthquake?" and then it's over.

For those who may not know, millennia ago, an ancient continent named Appalachia or something like that, collided with our east coast and added on to the north American plate in part also causing much of the Appalachian mountain chain as it collided and pushed inward.

The Appalachian mountains are some of the oldest in the world and now mostly worn down to nubs from weathering.

Apparently it is still trying to move and as a result causes the occasional, small earthquake along the upper eastern seaboard.

Yep. Back 300 or so million years ago the Appalachian mountains were as mighty as the Himalayans are today.

Yeah, truthfully, it only made the news because of the location and scarcity, but that does not rule out a significant earthquake there, I'm not sure what the supposed stresses are there, but I doubt that the odds of a pretty good earthquake there are not zero.

Just imagine the calamity now if NYC was hit by a 7.0 earthquake right in the middle of a war with all those old stone buildings with Mamdani as the mayor now? There is a non-zero chance it could happen.

Exactly. Mountains are the exact opposite of trees and vegetables. Plants start out small and get bigger with age, whereas mountains occur in some geological period of time as giants, then slowly erode away back to nothing with millions of years of wind and rain.

It's already sinking down due to the weight. And, the scientists which the left love so much, all say that California will eventually fall into the ocean and that a tsunami will wipe out the West Coast. Maybe even the East Coast.

No, mountains are first built up through orogenic events, such as plate boundary collisions (Himalayas) or volcanic eruptions (Hawaii).

So long as those orogenic processes are ongoing the mountains continue to grow. The Himalayas are rising at about one inch per year at present, and will continue to do so as long as the Indian Subcontinent is impacting that section of the Asian plate.

It is only after those seismic processes end, that the mountains are then ground down.

Really? In NYC too? I know they have that problem in other cities where they overestimated the bedrock and now they are getting uneven settling in the area causing all kinds of problems.

And, the scientists which the left love so much, all say that California will eventually fall into the ocean and that a tsunami will wipe out the West Coast.

Well, a Cascadia Event is a distinct possibility for the NW coastline.

We worry more about the man made "seismic" events in NYC than the natural ones.

Sooner or later someone's gonna figure out a package nuke, and we would be target #1.

Exactly. I was speaking in terms of human time scales. Yes, so long as a mountain still grows at an inch a year, that will far-outpace the weathering. The force behind the creation of the Appalachians ended a long time ago which is why they are now little more than rolling hills.

I was just watching a documentary on people climbing K2 and Mt. Everest the other day and it occurred to me seeing them sitting there on the summit what it might feel like if suddenly the mountain experienced a tectonic event.

Nope, the western part of California (the part west of the San Andreas Fault system) will be accreted to the south coast of Alaska, in about 5 million years if current plate movements continue.

And, the scientists which the left love so much

Haha, I love it when you guys obliviously self-own.

 

[Deplorable Yankee]

I can remember a four because I was up high in somebody's apartment and the chandelier started moving...
I felt buildings sway way harder in High winds

If the New Madrid ever goes off well I'm totally f*****

Does that mean Alaska will turn blue in 5 million years?
