A sinkhole is a topographical feature, like a glacial valley. The formation of a specific sinkhole is an event. Usually faster than the formation of a glacial valley (check for ice giants). The sink hole formation event may be the cause of other events (a car falling event), a road closing event, an emergency response event. It may bring about a state of affairs (an emergency situation, a road being closed). It may also have no affect on humanity (if a sinkhole forms in a forest and there is no one there to fall in to it). SimonReceived on Tuesday, 3 May 2016 13:50:09 UTC
