I'm just going by some foggy recollections of sophomore physics and hazy memories of newsreels. 1) I'm pretty sure that car bombs, even 1000 lb car bombs, don't leave craters. All the energy would go up and out; path of least resistance and all. 2) I've never seen a crater on any newsreel of a carbomb site. Not once. 3) Some witnesses report a rocket attack leading to the explosion - but there's no tank or howitzer that could do that much damage with one round. So, um, something's fishy at the bomb site today. There'll be more to this story.
The train bombs of 3/11 did not leave craters. That was a big-ass missle that tore up the hotel in Bagdad today. You're wondering who sent it and where'd they get it? Are the Russians entering this war?
Just to answer the question. In the 1st WTC attacks, there was a huge crater, but that was in the parking garage.
Was there a crater outside the Murrah (sp?) Federal Building in OKC? Now that you mention it, I don't recall one, but I could be wrong.
From a story about the Oklahoma city bombing in 1995? Did a missle cause that too? http://www.washingtonpost.com/ac2/w...ode=&contentId=A99330-1995Apr20¬Found=true The explosion itself blasted a crater eight feet deep and 20 feet in diameter that was filled with rubble.
Put a Black cat in some loose dirt and it leaves a mini-crater. It all depends on how powerful the blast is. If it is enough to overcome the strength of what is underneath it, hell yes it will leave a crater.
I would guess that the dirt in Iraq is based on much sand, too. Heck, when it rains in Florida, where sand is a major portion of the dirt, you can get major sinkholes that can swallow a house.
Heck a grenade on the sidewalk leaves a small hole, don't know if it's enough to be called a crater, but still.
If Karl had posted this... Which side would this attack put them on? Or are you talking about the Russians selling arms to the resistance in Iraq?
Creative suspicion, nothing more. Just imagine how the dynamics would shift if a player like that joined the war. But according to an AP report, eye witnesses claimed a rocket (missle?) went into the building.
oh dear. Rain doesn't cause sinkholes. And how in the world does rain in Florida and sinkholes have anything to do with bomb craters?
Maybe I'm missing something here, but so what if it was a missile attack?? The insurgents in Iraq have used them to attack civilian targets before...not as often as they've used car bombs, IEDs, and the like, but it isn't unheard of (the Palestine Hotel attack comes to mind).
No. I'm endorsing the idea that you can't build cities on top of swamps without the occasional city block being swallowed whole by the earth.
Here are some more instances of car bombs leaving craters. There goes that theory! Google works wonders.
I am all for learning. Someday, I would like to teach my children those little things we all should know. No need to get all snooty. We are not talking about rain exactly, but the ability for such things like sinkholes (which do have some relation to water) in such surfaces. I am talking about the land, the dirt in Iraq. Florida has sinkholes, but that was part of the thought process to determine that certain soils have certain characteristics. In that, one could guess that Iraq has some dirt with high sand content. The same idea that I know I can't plant certain trees in my yard due to the high local content of clay in the dirt. The same idea that helped create the world's most famous skyline in the world, Manhatten, built on some of the hardest and natural rock base on this planet. I could then guess that if you blow up a "bomb" on the surface with high sand content, the sand could/would move more easliy than say some other, more solid, dense subsurface. What causes sinkholes? Sinkholes are closed depressions in the land surface formed by dissolution of near-surface rocks or by the collapse of the roofs of underground channels and caverns. Sinkholes are a natural, common geologic feature in places underlain by soluble rocks such as the limestone and dolomite that form the Floridan aquifer system. Under natural conditions, sinkholes form slowly and expand gradually. However, activities such as dredging, constructing reservoirs, diverting surface water, and pumping groundwater can accelerate the rate of sinkhole expansions, resulting in the abrupt formation of collapse-type sinkholes, some of which are spectacular. source: St. John's Water Management District. http://waterquality.ifas.ufl.edu/PRIMER/h2o2.html#a7
I wasn't meanin' ta be snooty! sorry. But I am glad you learned something about Florida, however useless the information might be to you! By the way, the reason N.Y. City is able to build such humungous and tall skyscrapers is the same reason that Paris is unable to. The lack of substantial bedrock to support tall buildings has kept the skyline low. I'd wager that has much more to do with it than any artistic or "French" reasons. London, on the other hand, seems to have nothing of that problem as they have some pretty aggresive planes to drastically enhance an already impressive European skyline! whew!
