Description

This tag does not have a proposal, but it has an obvious meaning and it is somewhat in use in various places of the Earth (see taginfo or overpass turbo). A bomb crater may look similar to a natural=sinkhole, but the genesis differs. Some characteristics may help you tell them apart:

  • A bomb crater has a more regularly circular rim.
  • Part of the matter that a detonation removes from the centre gets deposed at the rim. That makes the rim elevated above the surrounding area until erosion levels it down.
  • Bomb craters are steeper at the edge than in the centre.
  • Most sinkholes are found in karst or mining areas, while bomb craters are found at former battle fields.
  • Former defense lines which are often located at hills were heavily bombarded. You often find bomb craters near the remains of defensive structures such as trenches.
  • Bomb craters often come in groups that span across areas independently from geological faults.
