On August 31, 1886, Charleston was nearly destroyed by an earthquake. The shock was estimated to have a moment magnitude of 7.0 and a maximum Mercalli intensity of X (Extreme). It was felt as far away as Boston to the north, Chicago and Milwaukee to the northwest, as far west as New Orleans, as far south as Cuba, and as far east as Bermuda. It damaged 2,000 buildings in Charleston and caused $6 million worth of damage ($133 million in 2006 dollars), at a time when all the city's buildings were valued around $24 million ($531 million in 2006 dollars).

While all dogs are genetically very similar, natural selection and selective breeding have reinforced certain characteristics in certain populations of dogs, giving rise to dog types and dog breeds. Dog types are broad categories based on function, genetics, or characteristics.
