HELP, looking for meteor settings

Worldevents just has frequency of the showers but not the actual settings I am looking for.

I have been looking for days and have not been able to find anything on this subject in the files or online that will help my cause.

I want to edit-
1. speed of the meteors
2. damage of the strike
3. AOE of the damage
4. amount of left over ore
5. Even script a event from the strikes damaged voxels (Want to be able to have a few spiders spawn from the hole that is left over) giving another dimension of difficulty to my server.

If anyone knows where to find these settings please let me know!

Please and Thanks...
