Key comment from a seismologist on CNN

[RandySF]

She said that the tremors spread so widely because the "crust" is not broken apart the way it is here on the West Coast.

1. Yep, and particularly under NYC, I believe that's solid granite. n/t

[Dreamer Tatum]

2. Then that crust needs to be broken NOW. Would create millions of jobs. nt

5. LOL!

I love you!

:rofl:

8. ha!

:rofl:

3. Yes it is ancient bedrock

so it resonates like a... bell. Literally that is the best analogy

4. Felt it in Pittsburgh

Scary! :scared:

[unblock]

6. the building i'm in (in connecticut) swayed for about 10 seconds

[fishwax]

7. I remember them saying that after the 2008 Illinois earthquake too

So the tremors spread farther and reverberate longer ...

[phantom power]

9. They need more fault li -- ! oh wait

[jwirr]

10. That makes sense. When a road crew was building a tunnel in an

area with solid rock base they warned people about the blasts that were felt miles away. Same thing here. Compact formations underground carried the tremors for many miles.

11. The crust on the east coast is actually stuffed

With cheese!

[dtexdem]

12. So the problem is that East Coasters are too crusty?

Yeah, I guess I can agree. ;-)

13. One of the idiot meteorologists was saying it was because of "soft rock"

And the soil was "younger" and not solid like it was on the West Coast. He had it completely wrong! I wish meteorologists would stick to making guesses about the weather instead of trying to explain stuff they know nothing about. I suspect he had heard something about soil liquefaction and was trying to apply his poor understanding to the geology of an area he knows nothing about.
