Earthquake on East Coast How bout that

Henning said:
If you're in the city or near a major highway, you probably feel what a 6.0 produces in ground shock on a relatively frequent basis. I have been in buildings in Manhattan over the subway that shake harder every 7 minutes.

When I first moved to San Francisco I kept waiting to feel an earthquake and was disappointed when it was just a truck or a bus going by.

You sure you're not thinking of the New Madrid fault? That's quite a way west of where this one was.

I'm pretty sure the Brooklyn Bridge and most of the tall buildings are on bedrock in NYC. They probably aren't designed for an earthquake though.

The two piers of the Brooklyn Bridge are in significantly different geology. Manhattan side is rock, Brooklyn side is "bottomless sand" or vice versa. It's what got Roebling as they kept going down and down with the caisson.

Really? Little ones happen in SF at night, too, so perhaps you slept through one.

The one earthquake I actually remember was at night. I woke up and remembered the advice to get under a door but I was sleepy and I pulled the covers over my head instead. :dunno:

I moved away before the Loma Prieta earthquake although I visited occasionally back then and more often now.

I always heard that you should stand in a doorway. Empty fields might work OK in the suburbs or the country but not so much in the city where there are plenty of things to fall on you if you are standing in the street.

Oh. Sorry. I've been out west too long and I forgot that the entire east coast is just one big city.

I wonder how many people in the park or somewhere open like that went into buildings to be safe from falling buildings and such..for their own safety of course.
 
The structural design was sound, but the build changes made it such that the Citigroup Tower in NYC was in danger of collapse from when it was first erected until late 1978. The public didn't know until almost 20 years later.

I guess it's a good thing no other engineering gaffes that big were hiding in any structures on the East Coast today. ;)

Of course, we could always get some workers to saw off the tip of Manhattan row it out to sea, and spin it around to keep it from settling... like one guy said could be done in the 1820's and everyone believed him...

You just gotta love this stuff.
 
We were eating lunch at the Lighthouse at Georgetown-Sussex County DE (KGED). I thought someone was kicking the table, then we realized the light fixtures were wavering and we could feel it in our seats. It was over in maybe 20 seconds without even spilling our iced teas. Traffic in the pattern continued unabated. :yawn:
 
Well, I prefer not to be on the 7th floor the next time a quake hits. Pretty bizarre with the vibration first, then the shaking and bouncing, and then the swaying. The swaying got the adrenilin jumped up...that is just freaky!

I remember that from when they were doing the repairs. Something about hurricane wind problems.

A skydiver buddy of mine has a window office way up in the Sears Tower. I visited him in his office one day and he has a full pack hanging in the corner, "This building ever burns, I'll get to base jump it... skydivers...:rolleyes2:
Not a bad idea though.

Most definitely, but we'd been friends since about 8yrs old, I could tell he just wanted an excuse to jump out the widow.:D

ummmm.....

The political jokes are bubbling out:
The Dems say the quake stated in a structure called Bush's Fault.
The Reps are saying the quake moved much more left than normal.

One experience with a mild quake in San Diego one evening was a bit confusing. I had had a couple drinks and had to get up early A.M. to relieve myself. I make quite a mess as the commode seemed to move around a bit and spoil my normally excellent aim. I was a bit murky about it until my Dad mentioned it was a mild quake. Didn't mind cleaning up so much then <g>

Best,

Dave

Obama's security staff has revised the TFR to now include most of washington and DC. Nature will just have to file the next time she wants to shake things up.
 
Earthquake here. Now. Tuned in to local news only radio station. They are getting calls from all around the area. Happened minutes ago. Probably a 4 on the scale. Lasted less than 5 seconds.

Quick jerk and then done.

One of those things we sort of shrug off here in California.

Update: it was epicenter'd 3 miles south of San Leandro. Only a 3.9 on the scale. Amazing how all I did was turn on my FM radio and I had the information. Little hometown (SF) "real" radio stations are awesome.

  1. wait a minute - earthquake centered on Virginia. Maybe God is mad they DONT have gay marriage?
  2. Michele Bachmann is readying her speech to ease the fears of everyone regarding today's earthquake in Washington State.
  3. There was just a 5.8 earthquake in Washington. Obama wanted it to be 3.4, but the Republicans wanted 5.8, so he compromised.
These are the ones I have seen. Most are pretty, meh.

A friend of mine (the guy who rigs the parachutes I have access to) tried to sell something like this to a tall building locally, and a group of them did jump off of the tower to prove it would work. The authorities didn't like the idea though, so it never became a commercial success. I was talking to him the other day, and he said that he always regretted that they couldn't find a way to make it viable. Especially when he was seeing the 9/11 footage of people jumping. Their product would have worked...

The quake would have continued, but it interrupted The One's golf game, and He commanded the earth be still.

Later, it was learned Oprah performing Zumba Dance led to the temblor.
