Bilberry reservoir collapse
The 1852 Holmfirth flood occurred when the embankment of the Bilberry reservoir collapsed, releasing 86 million gallons of water down the River Holme. It caused 81 deaths and a large amount of damage to property in the valley leaving many homeless and without work. The buildings and structures destroyed included four mills, ten dye houses, three drying stoves, 27 cottages, seven tradesmen's houses, seven shops, seven bridges crossing the River Holme, ten warehouses, eight barns and stables. An inquest after the disaster concluded that the reservoir was "defective in its original construction" and that "the Commissioners, in permitting the Bilberry reservoir to remain in a dangerous state with the full knowledge thereof, and not lowering the waste pit, have been guilty of great and culpable negligence".
1783 Calabrian earthquakes began
The 1783 Calabrian earthquakes were a sequence of five strong earthquakes that hit the region of Calabria in southern Italy (then part of the Kingdom of Naples), the first two of which produced significant tsunamis. The epicenters form a clear alignment extending nearly 100 km from the Straits of Messina to about 18 km SSW of Catanzaro. The epicenter of the first earthquake occurred in the plain of Palmi. The earthquakes occurred over a period of nearly two months, all with estimated magnitudes of 5.9 or greater. Estimates of the total number of deaths lie in the range 32,000 to 50,000.
