Last month's Moore, Oklahoma tornado caused severe damage in many portions of the city. Whole blocks were wiped out, as can be seen in this swipeable, before-and-after map created by the geographic information services company, ESRI.

What's most shocking, though, is how specific the damage was. Completely devastated blocks sit right across the street from neighborhoods that were largely spared. For example, as you scroll horizontally to the east, look at the difference between homes on either side of SW 149th Street. To the north, only rubble remains. To the south, the homes are still intact.
