The 1764 Woldegk tornado on June 29, 1764, was one of the strongest tornadoes ever documented in history, receiving the unique T11 rating on the TORRO scale along with an F5 rating on the Fujita scale and had winds estimated to be more than 480 kilometres per hour (300 mph).[3][4][1] The tornado traveled 30 kilometres (19 mi) and reached a maximum width of 900 metres (980 yd). Most of the information known about this tornado came from a detailed 77-paragraph study by German scientist Gottlob Burchard Genzmer, which was published one year after the tornado occurred.[5][6] The tornado completely destroyed several structures, and several tree branches reportedly thrown into the atmosphere. Many areas were covered with up to 2 centimetres (0.8 in) of ice.[4] The storm which produced the violent tornado was dry, with almost no rain reported. Large hail, reportedly reaching 15 centimetres (6 in) in diameter covered the ground. The hail caused significant crop and property damage, killed dozens of animals, and injured multiple people in a large stretch around the tornado and to the northwest of the tornado's path.
