Following on from Destruction by design - how best to go about crafting a ruined landscape? I'm asking questions about the signature destructive patterns of different weapons systems. This is the third, the first follow up deals with deliberate demolition type destructive processes and can be found here and the second here deals with orbital energy weapons.
This question is about the differences, if any, between the patterns of destruction caused by precision kinetic weapons, (those scaled to destroy buildings rather than whole cities), versus large conventional weapons like the grand slam and other massive bombs that detonate below the ground surface. Basically how different would a city ruined by orbital bombardment look to one devastated by seismic bombs?
Good answers will consider the initial effects of the bombing/bombardment but also the differences, if any, in the way such a devastated landscape ages as vegetation returns and weather takes it toll.
