Many boomtowns have become ghost towns over the years. Meanwhile, the term boomtown is used to describe a location which has seen a newfound resource of profitable activity appear, and which subsequently draws a population there. And often, as soon as the resource or industry disappears, so too do the people who inhabited the buildings. Thus, they leave behind a ghost town in the aftermath.
Similarly, changes made to an area’s infrastructure can divert people away from one town to another. This happened along the famous Route 66 – highways I-44 and I-40 proved to be faster options for motorists, so cities along the roadway eventually became deserted. The same happened with places along railroad tracks that fell out of use.
Meanwhile, dams have also flooded out towns, rendering them unlivable. Massacres in the midst of war, too, have left villages and towns empty. To that end, natural disasters have done the same, whether or not meteorologists have known to expect such a shift in weather. For example, residents evacuated the Italian village of Craco in the wake of a landslide in 1963 and never returned.
