Kentucky Disaster Was Nation’s Deadliest Non-Tropical Flash Flood Since .

The Kentucky flood disaster last week was American non-tropical flash floods in 45 years.At least 37 died in East Kentucky after 6 to 9 inch rain fell in just 12 hours last Thursday, triggered flood records in the North Kentucky River in Jackson and Whitesburg, and damaged floods in several other cities.

Some houses were swept away by floods that went berserk, and many more in the valley flooded.In the next five days, more than 1,300 people were saved, but the crew still encouraged to achieve those who were still cut off by landslides and the road or bridge was washed, according to the Associated Press.

With flash floods, we refer to floods that occur quickly in the order of minutes or hours, with rapid increase in rivers, tributaries, rivers or urban areas due to heavy rain in smaller areas.

Last September, the remaining storm Ida triggered a massive flash flood in the northeast which claimed 49 lives.

However, it has been 45 years since flash floods that are not related to tropical storms, storms or residues are the same turn off in the US like this latest Kentucky event.

On the night of July 19, 1977, up to 12 inches of rain in just eight hours leading to Overopping, then failed the Laurel Run dam and several other small dams, sending flood waves of 100 million gallons of water down a narrow valley along two miles to Johnstown, Pennsylvania.This giant water wall claimed 84 lives and caused $ 340 million in the city.

It happened 88 years after the most deadly Flash flood America, also in Johnstown, encouraging the construction of the Laulel Run Dam. The collapse of the South Garpu Dam after heavy rains on May 31, 1889, sent flood waves as high as nearly 40 feet through the valley, claiming 2,209 lives.

Three other flash floods in the 1970s claimed more than 100 lives: Big Thompson Canyon, Colorado, in 1976 (144 deaths); The Black Hills of South Dakota in 1972 (236); and Buffalo Creek, West Virginia (125).
