I was just reading though "Armies of the Night" and realized something.
The strike hitting Linden was listed at 1.25MT. So damage radius should be MUCH smaller then what the maps included show.
I am using this as a guide...

Is this example accurate?
Obviously radiation and subsequent fires and such would cause more damage. But the maps in the module show complete destruction for 10-12miles out.
