“Cuadrilla said it appreciated the tremor [of 2.9 magnitude] had ’caused concern for local people’ and said ‘it is worth noting that this event lasted for around a second and the average ground motion recorded was 5mm per second. … This is about a third of that permitted for construction projects.'” https://www.bbc.co.uk/news/uk-england-lancashire-49471321
However, there is a much higher requirement for destruction projects.
“From 1954 to 1999 the mountain hare population on moorland sites decreased by nearly 5% every year, which ecologists attributed to the planting of conifer forests on former grouse moors. But from 1999 to 2017 the scale of the moorland declines increased dramatically to over 30% every year, leading to counts in 2017 of less than 1% of original levels in 1954.
David Noble, chairman of the Game and Wildlife Conservation Trust in Scotland, said data gathered by the GWCT over the same period as the study does not suggest such a decline in hare numbers on grouse moors.
“…we look forward to reviewing it, especially how the counts were made, because assessing hare numbers accurately is challenging.”” https://www.theguardian.com/environment/2018/aug/14/scotlands-mountain-hare-population-severe-decline
“Saddleworth Moor is made up of peat, which is a particular health threat when it burns because of the large amounts of carbon it stores and the way it burns for long periods of time, emitting large amounts of smoke and tiny particulate matter. …
The bogs are a store to 200 years worth of industrial pollution, once produced by the mill towns of nearby Manchester and Sheffield. …
Research in Canada has shown harmful levels of mercury have been released during peat fires.
“Peat smoke contains many carcinogenic gases such as hydrogen cyanide, ammonia and benzene that could result in a longer-term increase in ill health and mortality in the smoke-affected population.”” https://www.telegraph.co.uk/news/0/manchester-wildfires-will-leave-toxic-legacy-scientists-warn/
Another good reason to leave grouse shooting estates to manage moorland by draining it and regularly setting fire to it.
