Where have all the earthquakes gone? Kansas and Ohio.

This is a short blog by a geologist in New Mexico about quakes caused by injection in the Kansas /Ohio area

Of course frackquakes are part of the scaremongerers’ armoury in Lancahire


But this is typical damage from a Mag4 quake in Los Angeles and few caused by even injection are that big.


In Kansas, seismic activity dropped from 1,967 earthquakes to 668 earthquakes over two years when regulations on oilfield disposal wells were applied. How did they achieve this?

All the Facts about Fracking – er – um

Ever since I started to find out what fracking entailed  I have been amuzed by the sheer nonsense put out by opponents of fracking. Worst are those who should know better like Friends of the Earth, Greenpeace  and Guardian Environment. They have been successful both in raising an awareness and hostility to fracking, but at times their followers/dupees come out with complete tosh.


Here is a prime example from a female protester at Preston New Road.  On 3rd of Sept this was posted on the FB page Lancaster fights Fracking entitled “All the Facts about fracking”

Here it along with my comments;

All the facts about fracking


I went to Preston New Road on Friday to demonstrate against the fracking company Cuadrilla. The idea was to go and stand outside cuadrilla’s gates to prevent deliveries etc from coming and going,

Is this actually legal? And how would she liked it if someone stopped her clients entering her premise for their “Neuroplastcity”?

this is what demonstraters were doing since March.
I found that the local people I talked to were very upset as the value of their properties had dropped 70% since Cuadrilla’s arrival.

Really! On what evidence? The evidence shows that house prices have not dropped

Fracking has already caused huge amounts of damage and fear in the area with ground tremors.

Yet another! Even tremors of Mag 2.3 don’t cause damage. This is simply falling for scaremongering

In 2011 at Preece Hall there were two significant tremors of Mag 1.5 and 2.3. Few felt them and no one reported any damages, though later some claimed that their property was damaged.

This image is useful. It shows that a Mag2.3 is about the same as a lightning bolt and that tremors that size are very common, with a about half a million every year. Further they are at least a billion times smaller than either the Nepal quake or the 2004 tsunami.


Fracking does cause seismic activity and many refer to 50 at Preece Hall. all but two were Mag 1 or less and would hardly cause a ripple in a teacup. Despite this many have used these “earthquakes” as a scare-mongering tactic and was used in the Greenpeace “Not for Shale” Campaign.


That was effective in conning locals and here its influence can be seen with concerns of “huge damage”. There was pretty clearly no damage.

The way the damage is caused is by enormous amounts of water poured a mile down

A profound mis-undrestanding of fracking. The water is pumped in under very high pressure, not poured.

into a pocket of gas,

I am beginning to despair. conventional sources have pockets of gas. Gas in shale is simply found in microscopic interstices in the shale.

This is a terrible misunderstanding. Some gas deposits, as in Holland, are found in underground caverns, but in fracking gas is extracted from shale, where the gas is found in the shale in tiny interstices in the rock. Hence in exploration a rough test is to put a piece of core from the shales into a “fish tank” and the amount of gas is indicated by the number of bubbles. There is simply no pocket of gas, but gas spread throughout the shale

this forces the gas up, along with all kinds of methanes

The gas is methane and there are no other kinds of methanes. This is so face-palming.



and other toxics.

Presumably a clumsy reference to the variopus stuff in flow-back

The drilling disturbs the land plates

This is simply hilarious and shows and incredible ignorance of even school-level geography. She is vaguely aware of palates but ain’t got a clue about plate-tectonics and quakes

and causes tremors and disturbances.

More guff

We heard that the government was going to start putting nuclear toxic waste down the drilling hole when the drilling was finished and cover it in! 😳 Terrifying !

If she hadn’t come out with such silly stuff before, I’d say she was lying. This is simply repeating someone else’s blatant lie.

There was about 50 or 60 of us and the same amount of police. People were very amusing , someone called to the police “I hope no one is getting robbed in Blackpool”
I can’t say I wasn’t a bit scared as I’d seen videos on FB the night before of the police being very rough indeed. Saying this, my own experience was that the long term demonstraters , who were there every day, were quite offensive to the police, but I saw why later!


We stood in the same spot outside the gates, as was customary , the police arrested one of our group for obstructing the highway.

That is illegal!!

We weren’t on the highway we were where we thought it was legal to stand. It turns out that Lancashire council had redesignated the land, that morning, to become part of the highway. The police are always talking about cooperation , if they had told us the facts, we would have moved , this was a really slimey way to get an arrest.
The police were arrogant , unpleasant and far too authoritarian, there were far too many of them, at one time one police person per demonstrator . Don’t we have a shortage of police ?

Well if you bait the police and continue pushing them to the limit, they may not be friendly.

We noticed an awful lot of support from motorists going past who beeped and waved.
Lancashire council voted against fracking

And a lot who didn’t beep. It was a the planning committee not the whole council

but a conservative minister over ruled this and granted a license !

No, the minister did not over-rule it. Cuadrilla appealed as is their legal right and after much evidence was taken, the minister upheld the advice of the Planning Officer


It seems it makes no difference to this government what the public want, they just need to get their hands on more cash and deal more destruction to our environment!

More of the usual mantras!

I am afraid i didn”t find one fact in this article




The author is a lady working in Lancaster and according to her FB page is;

As you read it you will see she makes a lot of statements about fracking and the behaviour of the police at the fracking site near Blackpool.

The post has been shared 40 odd times, including to to RAFF and RAG. If RAFF and RAG shared it , why didn’t they correct its howlers. It makes you wonder!

Assam Earthquake 15th August 1950

As we mark the 70th anniversary of India and Pakistan, we would also remember that the Assamese did not have a good day on the 15th August.

During the night a massive Mag 8.6 earthquake struck the area, with its epicentre just inside Tibet.That makes it far bigger than the Mag 7.8 in Nepal in 2015. However the damage or loss of life, though considerable, were far less as the area was less densely populated.

My own interest is that we were living in Jorhat on the tea plantations of Assam at the time and the quake became part of family history. We lived in a bungalow, which was built on stilts for protection against earthquakes and had about ten servants as was the norm.

So what happened?

The bungalow on stilts began to sway. Wardrobes fell over, but didn’t hit anyone.

The car, an american Studebaker, rolled out off the garage onto the lawn.

My parents took my brother and I to spend the night in the car.

In Jorhat there was much damage, but also poetic justice. There were acute food shortages and grain sellers kept their grain hoping to get higher prices. However the quake collapsed many of the warehouses and then the price dropped. Locals imply went in and took what they wanted.

The other personal detail concerns a friend of my parents, Frank Kingdom Ward, a botanist and plant-collector. He was known to be in the vicinity of the epicentre and was actually sleeping on top of it. nothing was heard of him for three months when he re-appeared. On 16th August he had intended to botanise in a Himalayan valley, but that was partly filled in with landslides. He slowly made his way out and returned to safety.

For further details read

Not surprisingly that is the biggest quake I’ve been in. When I was working at Kilembe mines as a geologist in the Ruwenzori Mountains of the Western Rift Valley smaller quakes were common. we often had Mag 3 to 5 quakes and as they did no damage we almost ignored. The most memorable one was during a church service at All Saints Church, Kilembe. Halfway through a hymn a quake struck and the whole church (wooden) shook violently. The organist missed a note and carried on. Nobody mentioned afterwards.

Two years earlier a Mag 6.5 hit the northern Ruwenzori and a dozen were killed, including the son of a vicar Rev Mikairi Nturanke, who I later knew well and went to a harvest service in his church. I preached my first sermon there!

Since then I’ve felt a few quakes in Britain but none more than 5.  the biggest caused a little damage but no injuries.

Living in Lancashire now, we often have unfelt Mag2s and occasionally a bit more but I have never felt any.

This biggest were those of Preece Hall fracking in 2011 being up to Mag 1.5 and Mag 2.3 . They were hardly felt and did no damage , despite dubious claims. The biggest damage was to the minds of certain people who read about them later and wrote creatively about them.


Many don’t grasp the Magnitude scale. I am rather simplifying and seismologists might like greater precision, but this gives the picture.

From this you will see that the fracking quakes of Lancashire were no more than lightning bolt, that the Mag 8.6 in Assam  was far greater than the explosion of Mt St Helens and about the same as Krakatoa.

Even the quakes, due to injection into wells,  of Oklahoma which are mostly about 3 to 4 are trivial compare to those of the 2004 tsunami, Nepal 2015 and Assam 1950




From the diagram above it is clear that any quake of less than Mag 4 does not cause significant damage.

Below is a map of quakes in 2017 showing that nearly all are confined to the Pacific Ring of Fire or the Alps-Himalaya Tectonic belt
