A micro seismic event of 0.76ML (local magnitude) was detected just after 11.30am this morning at Cuadrilla’s shale gas exploration site in Preston New Road, Little Plumpton, Lancashire. Cuadrilla was hydraulically fracturing the shale rock adjacent to a horizontal well at the time and the seismicity is classed as a red event in line with the traffic light monitoring system regulated by the Oil and Gas Authority (OGA). Operations have now paused for the next 18 hours during which seismicity levels will continue to be measured. The British Geological Survey (BGS) records seismicity to one decimal place and therefore have recorded the event as 0.8ML (local magnitude).
Micro seismic events such as these result in tiny movements that are way below anything that would be felt at surface, much less cause any harm or damage. Without the sophisticated monitoring in place at Cuadrilla, they would not be detected. It is reassuring that the monitoring and traffic light system is working as it should. All the relevant regulators were informed without delay and we have verified that the well integrity is intact. As per the hydraulic fracture plan in place at Preston New Road, work will now pause for at least 18 hours and is expected to recommence in the morning (Saturday, October 27, 2018).

Don't panic there was a much bigger one recorded off Formby in August (1.2) and as of today Formby is still there.
In fact these are way below normal seismic activity but I am sure the energy nimbies will try and wip up some ill informed hysteria as they sit round their gas fires and filthy wood burners.
We could bring up the vibrations set up by wind turbines.

It's not what we can feel or see happen with fracking that we should fear, it's what we can't see, which is what effect it is having on our water supply.
Which do you value more - cheaper heating or toxic water? You can't have both!

Apparently you can have both if done properly https://www.bbc.com/news/uk-37578189
God forbid we let science get in the way though.

Could you give an example of how the fracking in Lancashire is or could be affecting our water supply ?

The limits have been set, They are going over them, They need to find out why and if they can't get them under control I guess the fracking will stop. They're not even fracking yet are they?

As the site is monitored by more detectors than anywhere else in the Universe HOW do you know these minor unfelt tremors are not happening all over the Country right NOW.
Fire and the wheel are too much for some people Nuclear bomb testing went on ALL over the Earth in the past and it hasn't imploded yet so trying to find alternatives for the day when Putin closes the valves on gas pipes to this Country is rather an urgent problem.

No I can't, I'm not a "professional" engineer. But I do know that this will not eventually be the only fracking site in this region.
I used to believe in the medical profession to always give me the best treatment for any medical condition from which I should fall victim. I don't any more having been a victim of their incompetence at the highest level due to their greed, their lies and their arrogance. I now have utter contempt for many of them after they needlessly ruined my life with no chance of any compensation due to the way they have done it.
So why should I believe the words of the similar breed of "professionals" in which you are prepared to have 100% faith?
Don't come crying to me if your water supply is suddenly cut off for the next 30 years.

Like everything else, the media make a huge thing out of nothing. When coal mines were opened many years ago, there were always several earth tremors - just as there is with anything involving movement within the earth. Tin mining, copper mining etc.,
Fracking occurs within the outer crust of the ground. Within the oceans this crust is about five miles deep, on the continents it is up to 25 miles deep. Fracking drills down to at most 1.5 miles into the ground.
The larger an earthquake is the deeper its epicentre. Yes, tremors occur all across the UK regularly, they are not earthquakes and most are not even felt. But yes, also there have been more earth tremors at fracking sites - just as in coal mines, tin mines, etc.,
The chemicals used include H20, more commonly known as water - sand and silicates, and chemicals to prevent blockages - these chemicals are commonly found in many food products by the way. The only risk is that if the highly salted water formed within the deoxygenated shale may find its way into the rivers that are a source for our domestic water. This is only a very slight risk.
I am not an expert on geology - but I would have thought that the underlying bedrock in our area was not suited to finding profitable black shale. I may be wrong - but several drilling sites have been started and found to be unprofitable.
However - if it is profitable, then the UK would gain far more than it did from mining previous minerals, which can only be good for the economy. Several European countries do not have that resource.
