Here is an interesting link that will let you calculate the effect of any type of impactor on the earth. Im not sure of the Algorithyms they used, or how accurate they are, but its results are quite interesting.
you choose the type of impactor, the speed and angle of trajectory, and where it strikes the earth, it will give you an idea of what could cause a 10 meter wide crater in a city, you might be surprised on how small the impactor could be to cause this scenario. http://www.lpl.arizona.edu/impacteffects/

Thanks for the link! I played with the variables for some time, but was unable to adjust enough to get a resultant crater anywhere close to my original 10 meter crater example. It appears that either a much larger crater will be formed or non at all. The closest I could get was by using a hard rock asteriod with low atmospheric entry speed and high angle of impact that left of crater field due to the breaking up of the asteroid in the atmosphere.
I was surprised to find that even a 40 meter iron asteroid hitting at 90 degrees would cause a crater between .5 and 1 mile wide with not much damage to people or buildings 30 miles away. Judging from this, I'd say that an asteroid that left only a 10 meter crater "field" wouldn't do much damage to anything or anyone not too terribly close to the 10 meter area of the field except for a bit of wind and some loud noise. Hmmm.... might still get some major attention though especially if in the middle of a major city.
