Great Baltimore Fire and piers lining the north side of the old "Basin" (today's "Inner Harbor") of the Northwest Branch of the Baltimore Harbor and Patapsco River facing along Pratt Street. It is considered historically the third worst conflagration in an American city, surpassed only by the Great Chicago Fire of 1871, and the San Francisco Earthquake and Fire of 1906. Other major urban disasters that were comparable (but not fires) were the Galveston Hurricane of 1900 and most recently, Hurricane Katrina that hit New Orleans and the Gulf of Mexico coast in August 2005. One reason for the fire's long duration involved
Great Salem fire of 1914 consisted of 5,826 buildings on at an assessed valuation of US$37.25 million. The streets were wide. Building codes were dated, not mentioning standpipes, fire escapes, or sprinklers. Salem had 180 fire alarm stations or boxes that could be used to contact telephone operators. A long drought preceded the events of June 25, 1914. The Great Salem Fire started with a series of explosions, caused by a mixture of acetone, amalacitate, alcohol, and celluloid. At 1:37 p.m. (EDT) on June 25, 1914, a fire alarm box was used to report a fire in the Korn Leather Factory at 57 Boston Street.
