The Hurricane of 1900, also known as the Great Galveston Hurricane,〔Trumbla, Ron. ("The Great Galveston Hurricane of 1900" ) NOAA Celebrates 200 Years of Science, Service and Stewardship〕 made landfall on September 8, 1900, in Galveston, Texas, in the United States.〔Gibson, Christine. ("Our 10 Greatest Natural Disasters" ) ''American Heritage'' (August/September 2006). Archived from (the original ) on December 3, 2008〕 It had estimated winds of at landfall, making it a Category 4 storm on the Saffir–Simpson Hurricane Scale. It was the deadliest hurricane in US history, and the second costliest hurricane in U.S. history based on the dollar's 2005 value (to compare costs with those of Hurricane Katrina and others). The hurricane caused great loss of life with the death of between 6,000 and 12,000 people;〔Weems, John Edward. ("Galveston Hurricane of 1900" ), Handbook of Texas Online〕 the number most cited in official reports is 8,000, giving the storm the third-highest number of deaths or injuries of any Atlantic hurricane, after the Great Hurricane of 1780 and 1998's Hurricane Mitch. The Galveston Hurricane of 1900 is the deadliest natural disaster ever to strike the United States. The second-deadliest storm to strike the United States, the 1928 Okeechobee hurricane, caused more than 2,500 deaths, and the deadliest storm of recent times, Hurricane Katrina, claimed the lives of approximately 1,800 people. The hurricane occurred before the practice of assigning official code names to tropical storms was instituted, and thus it is commonly referred to under a variety of descriptive names. Typical names for the storm include the Galveston Hurricane of 1900, the Great Galveston Hurricane, and, especially in older documents, the Galveston Flood. It is often referred to by Galveston locals as the Great Storm or the 1900 Storm. ==Meteorological history== The storm's origins are unclear, because of the limited observation ability at the end of the 19th century. Ship reports were the only reliable tool for observing hurricanes at sea, and because wireless telegraphy was in its infancy, these reports were not available until the ships put in at a harbor. The 1900 storm, like many powerful Atlantic hurricanes, is believed to have begun as a Cape Verde-type hurricane—a tropical wave moving off the western coast of Africa. The first formal sighting of the hurricane's precursor occurred on August 27, about east of the Windward Islands, when a ship recorded an area of "unsettled weather." The storm passed through the Leeward Islands on August 30, probably as a tropical depression as indicated by barometric pressure reports from Antigua.〔 Three days later, Antigua reported a severe thunderstorm passing over, followed by the hot, humid calmness that often occurs after the passage of a tropical cyclone. By September 1, U.S. Weather Bureau observers were reporting on a "storm of moderate intensity (not a hurricane)" southeast of Cuba. Continuing westward, the storm made landfall on southwest Cuba on September 3, dropping heavy rains. On September 5, it emerged into the Florida Straits as a tropical storm or a weak hurricane. The Weather Bureau ignored reports from Cuban meteorologists because they expected the storm to curve northeast along the coast of North America: "Assumption became fact as the official government reports stated, wrongly, that the storm was traveling northeast in the Atlantic." However, a region of high pressure had pushed the storm to the west into the Gulf of Mexico. The storm was reported to be north of Key West on September 6, and in the early morning hours of Friday, September 7, the Weather Bureau office in New Orleans, Louisiana, issued a report of heavy damage along the Louisiana and Mississippi coasts. Details of the storm were not widespread; damage to telegraph lines limited communication.〔 The Weather Bureau's central office in Washington, D.C., ordered storm warnings raised from Pensacola, Florida, to Galveston. By the afternoon of the 7th, large swells from the southeast were observed on the Gulf, and clouds at all altitudes began moving in from the northeast. Both of these observations are consistent with a hurricane approaching from the east. The Galveston Weather Bureau office raised its double square flags; a hurricane warning was in effect. The ship ''Louisiana'' encountered the hurricane at 1 p.m. that day after departing New Orleans. Captain Halsey estimated wind speeds of . These winds correspond to a Category 2 hurricane in the modern-day Saffir–Simpson Hurricane Scale.〔 By early afternoon on Saturday, September 8, a steady northeastern wind had picked up. By 5 p.m., the Bureau office was recording sustained hurricane-force winds. That night, the wind direction shifted to the east, and then to the southeast as the hurricane's eye began to pass over the island just west of the city. By 11 p.m., the wind was southerly and diminishing. On Sunday morning, clear skies and a breeze off the Gulf of Mexico greeted the Galveston survivors.〔 The storm continued on, and later tracked into Oklahoma. From there, it continued over the Great Lakes while still sustaining winds of almost 40 mph (as recorded over Milwaukee, Wisconsin) and passed north of Halifax, Nova Scotia, on September 12, 1900. From there it traveled into the North Atlantic where it disappeared from observations,〔 after decimating a schooner fleet fishing off the coast of Newfoundland. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1900 Galveston hurricane」の詳細全文を読む スポンサード リンク
