For information - the Richter scale - note 1 and 2.
https://simple.wikipedia.org/wiki/Richter_scale
The largest associated with the Lancashire fracking 2.3
The largest earthquake in the wider Lancashire NorthWest area - April 2009 Ulverston 3.7, Blackpool in the Irish Sea May 2011 3.3 and Kirkby Stephen 4.1 in August 1970 (and I remember that one shaking my childhood house near Windermere) and Longtown 4.7 in Dec 1979/ The biggest in the UK in the last 50 years was 5.4 in Gwynned in 1984
So let's get this in perspective, tremors from fracking are minimal in terms of potential damage. Coal mining has triggered more intense ones. So, no fracking, we are happy being dependent long-term on Russian and Qatari gas imports for our cookers, hearing and tricity gen - me thinks not.
