Thus looking at the US for example, a regional map could be the "Midwest", or the State of Illinois, or the County of LaSalle, or even the Illinois Valley - which is part of LaSalle County.
So a regional map is smaller than a world map, yet larger than a city map. There is a wide range of possibilities in describing a regional map. In the example of a regional map for this challenge, I think going towards the more localized is better since such a map could more easily show how the catastrophe has affected the local population. Something like a 10 mile by 10 mile square region, rather than a 100 mile by 100 mile region - though both fall under the category of regional map.
Thus the region affected by Mount St. Helens, which might be a 50 x 50 mile or even a 100 x 100 mile region would certainly apply to a region. If the map only featured the volcano and the immediate communities surrounding it, thus a 10 x 10 mile area, it would still be regional.
I don't see an additional category of local map as existing at all, other than describing a smaller region.
