I'm writing a novel involving worm holes and asteroids/meteors

I thought it would be best to ask the experts in the field to make sure I don't get lynched when this book comes out.
Please help however you can. The date during this particular incident is Feb 14, 2016, 11:47 pm western time, the point of observation is Vancouver, B.C, Canada. A wormhole opens up exactly 270,000km away from earth making the first quarter moon appear to have a hole in it. From this wormhole thousands of asteroids/meteors , varied in size from 1 square meter to 250 square meters, barrel towards earth in varied speeds from 17km per second to 30km per second. The astral objects are comprised of a heavy (Fictional) titanium and diamond composite alloy. Please give me theories/estimates on where the damage/impact area might be as well as how long it may take these objects to pummel earth. I think its 2-3hrs from wormhole to earth (impact/travel time).

Well presuming that they are travelling straight for Earth the lowest speed will arrive in 15882.35 seconds (4 hours ~25 minutes) and the fastest will arrive in 9000 seconds (2 and a half hours). I can't tell you where they will land but if you google "moon position calculator" there are plenty of sites that might be able to tell you.

As for the damage I take it that you meant cubic rather than square metres? If so we can take an average volume of 125.5m3, an average speed of 23.5kmps and a mass of (assuming a 1:1 mix of http://www.google.com/search?q=titanium+density" for nearly ten seconds).

Working out the http://en.wikipedia.org/wiki/TNT_equivalent" [Broken] and simply chose an area of the world you are familiar with then select a demo nuclear bomb as close to that figure and see the devastation it would cause. Interestingly you also have an option of choosing an asteroid strike equivalent to that which killed the dinosaurs.

* Titanium density ~4507kg/m3
** Diamond density ~3500kg/m3
