What caused the environmental problems experienced by the ancient seaport, Troy?

Large numbers of Greek soldiers milling about for the better part of a decade.|||Lots of things: Earthquake, Drought, Fire, etc.





Their have actually been numerous cities on the site of the city of Troy. The earliest dates from about 3000 BC to the latest in the 1st Century BC. Each city collapsed for particular reasons.





Two examples are:





Around 1300 BC, the city experience a major earthquake and was destroyed and abandoned.





Around 1200 BC, the city show evidence of a massive invasion and fire (The Trojan War?)





Peace!
