The 1900 Galveston hurricane, also known as the Great Galveston Hurricane and the Galveston Flood, and known regionally as the Great Storm of 1900 or the 1900 Storm, is the deadliest natural disaster in United States history. The strongest storm of the 1900 Atlantic hurricane season, it left between 6,000 and 12,000 fatalities in the United States; the number most cited in official reports is 8,000. Most of these deaths occurred in and near Galveston, Texas, after the storm surge inundated the coastline and the island city with 8 to 12 ft (2.4 to 3.7 m) of water. It remains among the deadliest Atlantic hurricanes on record. In addition to the number killed, the storm destroyed about 7,000 buildings of all uses in Galveston, which included 3,636 demolished homes; every dwelling in the city suffered some degree of damage. The hurricane left approximately 10,000 people in the city homeless, out of a total population of fewer than 38,000.
