We will be in touch
?
yes, totally.
the watford gap is the second most active fault line in Europe.
oh please.
this has to be a wind up.
getting bored of stupid questions now.
has someone "borrowed" kaesaes account to troll with?
No Kaesae, it couldnt
Yes Olly, it could. Ever is a long time!
I don't think so.
Lots of little earthquakes due to the country slowly springing back into shape after having been squashed by lots of ice during the ice age (no, not last Winter).
But we're not near the edges of any tectonic plates.

Yes.
But equally, one day they could be a boy born who could swim faster than a shark.
Well it could but would be so far off into the future it wouldn't affect you - we aren't close enough to any Techtonic plates to feel proper earthquakes - we do feel aftershocks and very small quakes but not ones big enough to do proper damage.
As the Techtonic plates keep moving (one is being pushed under the other) - we are slow moving towards the edge of a plate and then we could well discover the joys of big quakes - but it's so far off into the future it isn't something we need to worry about as we'll be long gone and well past worm feed by then (assuming you don't believe in reincarnation in which case it will get you at some point!).
Ever is a very long time.
Edinburgh Castle on the plug of an extinct volcano. The north western tip of Scotland was once part of the North American plate. Loch Ness is on the line of the Great Glen Fault and they reckon that the highlands of Scotland were once higher than the Himalayas.
Why couldn't it happen? There is no proof that it couldn't.
Actually it could happen, and quite soon.
As any student of history knows, huge amounts of coal, iron, lead and other minerals have been mined out of this country over hundreds of years.
It is a badly kept secret in the higher echelons of government that this has now reached a critical level, such that Britain is now only a few thousand tonnes away from starting to float.
Were this to happen, there would of course be huge "earthquakes" as Britain slowly sailed off into the Atlantic (or crashed into France, depending on the prevailing winds).
Fortunately, Steps have been Taken.
When the gravity of the threat was first realised, the Channel Tunnel was immediately put in place as part of a top secret deal between Britain and France to anchor our country firmly to Europe. To allay public suspicion it was explained away as being needed for "transport", but this was just a ruse to prevent widespread panic.
If that fails (as is widely expected) then "Plan B" is to utilize the vast numbers of propellers (ingeniously disguised as "wind turbines") that have been placed around the country. These will guide the country in whatever direction is desired. All that is needed for this to happen is to reverse the direction of flow of current from the National Grid. A single flick of a switch and we will finally control our own destiny.
Our great country will become a true seafaring nation, as it sails majestically around the oceans of the world, and a new era of British sea faring dominance will have begun.
Why couldn't it happen? There is no proof that it couldn't.
Well, except for the fact that big earthquakes happen on plate boundaries, and we're not near one. In a few hundred million years, perhaps, but in anything approaching a human timescale it's extremely unlikely.
luked2 - I salute your creativity in the field of paranoid fantasy 🙂
(unless you weren't being tongue in cheek, in which case you're mad as a box of hats)
luked2 - brilliant! 😆
High 5s Luked 🙂
luked2 - it must be true - I just read it on STW forum. Inspired post that one 🙂
I survived the Dudley earthquake.
In fact, I slept through it 😕

Brilliant
If that does happen, can we anchor it somewhere a bit warmer pls.
Well, except for the fact that big earthquakes happen on plate boundaries ...
Not always ...

Full speed ahead Capt Luke - can we go South a few hundred miles?
We're nearer to a plate boundary than you think. How do you think the Alps and the Pyrenees were formed?
oh please.this has to be a wind up.

How's it a 'stupid question'? Perfectly reasonable one to me, and one that could lead to some interesting and enlightening responses. It's your response that's stupid, if you ask me.
The simple response would be "we're not on a fault line, any quake would be minor".
We're nearer to a plate boundary than you think. How do you think the Alps and the Pyrenees were formed?
Plenty distant enough to dissipate quake energy to the point where we'd bearly feel it.
I know where the plate boundaries are!
Depends what you mean by big I suppose:
Research suggests that the largest possible earthquake in the UK is around 6.5.
From the BGS website.
If Leeds hadn't gained promotion on Saturday we could have had one - epicentre Elland Road, Leeds, West Yorkshire.
They think a large movement of plates of southern Ireland caused a tsunami to devastate the Somerset levels a few hundred years ago.
The original church on top of Glastonbury Tor was demolished by an earthquake. Either it was a big quake, or building regs were still in their infancy 🙂
why Kael?
You thinking of putting some of your special grease in the faultline to make the plates slide over each other easier? 👿 😀
(sorry couldnt resist getting in there before someone else did!)
Our great country will become a true seafaring nation, as it sails majestically around the oceans of the world, and a new era of British sea faring dominance will have begun.
And we shall indoctrinate the world with political correctness, force foreigners to become health and safety obsessed and we'll ensure everyone has free healthcare and an unbelievable raft (groan) of other benefits.
erm - have you all forgotten the earthquake last year? It was something like 8 on the richter scale and made lots of chimneys fall down. Lots of people were shouting about it the next day, but i managed to sleep right through it (and was only about 8 miles from the epicentre).
So - yes - large earthquake could and did hit britain.
Lol! 8 on the Richter scale is the same as the 1906 San Francisco one and the 2008 Sichuan that killed 68,000 people. The one you slept though was NOT a big earthquake, otherwise by definition you'd have woken up and it'd have toppled more than a few chimney pots!
How could it have been large and so benign?
The UK is on a fairly stable piece of continental crust, and unlike the Pacific, the North Atlantic isn't ringed by subduction zones.
Iceland is one of the nearest plate boundaries to us, but as this is on the mid Atlantic mid ocean ridge it is a constructive plate margin (ie volcanic activity leading to the production of new crustal rock) rather than a destructive plat margin (subduction zone).
The Alps are indeed the result of active plate movements - the African Plate colliding with Europe - much of the volcanic and seismic activity with this collision is associated with the various micro-plates in the Mediterranean.
So in geological timecales - yes, but likley to be very far into the future.
In human timescales - very very unlikely
the 2008 quake (biggest in 25 yrs) was 5.2 not 8
http://www.earthquakes.bgs.ac.uk/
thats alot more than I would have thought in last month
(although all only a similar intensity to my wife having a good fart!)
http://www.geologyshop.co.uk/ukequakes.htm
The average recurrence the UK may expect can be described as follows:
an earthquake of 3.7 or larger every 1 year
an earthquake of 4.7 or larger every 10 years
an earthquake of 5.6 or larger every 100 years.
Geologists know their stuff ok, but they seem pretty bad at web design.
At the risk of swelling his head, further repsect innit Luke. 😀
So which tyres for a 4.7 earthquake?
The average recurrence the UK may expect can be described as follows:
an earthquake of 3.7 or larger every 1 year
an earthquake of 4.7 or larger every 10 years
an earthquake of 5.6 or larger every 100 years.
That may or may not be right, but it's based on a very small database and may not be correct. The New Madrid event that I mentioned above would not be expected from an analysis like that.
yeah....but u will probly be dead before it happens...
it could happen given enough geological time as indeed could almost anything given enough time..... except you seeing sense that will never happen
Q. which tyres for an earthquake?
A. Specialized Ground Controls
OK - i was a little over enthusiastic about the scale (should have googled it first) i was just disappointed to have missed it when my parents 100miles away didnt! - [url= http://www.earthquakes.bgs.ac.uk/recent_events/uk_special/market_rasen_27022008.htm ]earthquake info[/url] but is that not still a sign that a 'large' earthquake could happen?
What is the definition of 'large'?
Evening.
By large I mean 6.5 to 7.5 on the richter. Isn't it a lot more likely that because of all the mining especially for oil that earth quakes will occur a lot more frequently.
After all doesn't the oil act as a large dampening unit for the crust, what woulds happen if a large piece of crust suddenly broke of and sank?
This is from my other thread but I thought you would be more likely to help me research it.
I've been having more of my crazy thoughts.
As I said the earth must realign its self to the cosmos and to do this it must tilt on it's axis.
Which is what it appears to be trying to do!
http://www.breakingnewsandsport.com/chile-earthquake-knocked-earth-off-its-axis/6191050/
What if this and all the other large scale earth quakes are just signs that this event is drawing closer.
Look at it this way, if we are seeing an increase in massive earth quakes and eruptions and also extreme weather it's because there is pressure building under the earth’s crust.
The magnetic north is also moving,
http://news.nationalgeographic.co.uk/news/2009/12/091224-north-pole-magnetic-russia-earth-core.html
We can see from every day events that there is something happening under the earth’s crust.
Are we to believe that these events and climate change are not related? That the amount of energy that is being produced at the centre of the earth has no effect on weather patterns?
Some of the energy that the core of the earth gives off will be in the magnetic and electro magnetic spectrum, it will therefore have an effect on physical matter.
I want to investigate what's happening. Why let a bunch of government lackies tell us what's going on.
I know I'm a brain farting idiot but I'm still prepared to have a go at finding out.
We all know that something is happening, I will stop mucking about and investigate this, for once single track will you work together to see what we can find out?
Some strong but not too destructive in Ferry Meadows based in Peterborough with damaged roofs being the worst.
Sounds like someone rolling their wheelie dustbin out!
Wasn't there a constructive zone between England and Scotland?
I dunno but I ran out of my house when the Earthquakes have happened!
zaskar are the earth quakes happening more frequently and how much longer is their duration, a lot is being made about the intensity and nothing about how long they last.
Surely the amount of energy being released is decided to some extent by how long the quake lasts. How exactly does the richter scale work, anyone know?
Umm Kaesae.. do some reading up and you might find out why none of what you wrote makes any sense!
By the way there are a fair few experts on STW in various subjects like climate and geology. They are already good at finding out 🙂
Hey molgrips.
I've taken your advice and did some reading, turns out umm isn't an actual word?
That shows what you know!
I don't want to do loads of research, as you have said there are a lot of experts on here with years of knowledge and understanding.
I would simply like to add my capacity to investigate the situation and analyze information from an unusual perspective to the mix.
What's the point in me starting from scratch, when all I need to be able to do is ask the right questions.
That said here are three questions just now.
1) Are there forces within the earth’s crust or core of the planet, that we can determine from observing the frequency, intensity and duration of events like earth quakes or eruption and also tsunami like occurrences, that are increasing?
2) Is there a correlation between the increase in how frequent these events occur and the increase in unpredictable or extreme weather aka climate change?
3) Have events like this happened before in the earth’s past and if they have would they have left a trace anywhere that we could use to study the frequency intensity and duration of the event. Either in geology or similar sciences?
I don't need to be an expert all I need to do is ask the right questions, I would love to research this but I have more work on than I can do as it is. The bottom line is I have no time!
I've just read this :
Our great country will become a true seafaring nation, as it sails majestically around the oceans of the world, and a new era of British sea faring dominance will have begun.
Truly brilliant 😀
You've set the bar pretty high luked2, I wouldn't be in too much of a rush to match that again
.......although I'd be delighted if you did 8)
I don't think so.
Lots of little earthquakes due to the country slowly springing back into shape after having been squashed by lots of ice during the ice age (no, not last Winter).
Called isostatic response
earthquakes are nowt to do with oil, or lack of it. Or coal, gas or any other natural resource.
Apologies if I oversimplify it, but I'm not a geologist...
the earth's crust is made up of lots of plates which move around over the hot bit, the mantle. What makes them move is the convection currents in the mantle. Some plates are moving apart, others are moving together, and some are sliding along parallel to each other.
Where the plates are moving apart, new crust comes up from the mantle in the form of lava. Best example is the mid-Atlantic ridge, where the North American plate and Eurasian plate are separating. The results here are mostly underwater, with the exception of Iceland and its many volcanoes.
The Hawaian islands are right in the middle of the Pacific plate, so you wouldn't expect any of this to affect them - except that there's a "hot spot" under the crust where magma bubbles up to the surface quite slowly (in comparison) to create "Shield volcanoes" like Kilaueia and Mauna Kea (sp!). This is how this particular island chain is being created
where the plates are moving together, one dives under the other - this is a subduction zone - occasionally "sticking". When they unstick, they do so very quickly, creating an earthquake. Further away from the subduction zone, the crust buckles up to form mountains. Sometimes in those mountains, the crust cracks right down to the mantle, allowing magma to seep to the surface to form a volcano like Mount St Helens, Vesuvius or Mt Etna.
Where the plates move parallel to each other, again they often stick, and when they unstick, you get an earthquake. I may be wrong but I think the San Andreas fault in California as an example of this
There are earthquakes & volcanoes happening all the time; it's just that these days with 24 hour multi-channel TV, we get to see more reports. No more or fewer than normal, they're just being reported more/better
Kaesae
1) No. Geologists look at timescales of millions of years, so a few in a couple of years is nothing. It's impossible to deduce global geological trends in a human lifetime or even thousands of lifetimes. All we have to go on is the geological record. There have been periods of high volcanism in the past and low volcanism, but I would think that earthquake activity would be very hard to determine from the geological record. Big earthquakes can only be found in the past from either historical records, if there are any, or from the things that they cause eg giant mudslides, mega tsunamis etc.
2) I would say no, see above. Climate can change at least locally in a few hundred years, or even 50 or so. Geology has a vastly longer timescale, which in itself would tend to steer us away from any link between the two. A couple of billion years ago though it was a different story - volcanism created lots of Oxygen in the atmosphere and also water, which allowed life to evolve. But that took a long time!
3) In the geological past, all sorts of things have happened. A few earthquakes in a few years is absolutely postively nothing compared to what's gone before!
Re oil and gas extraction - this sort of thing produces small tremors as the rocks settle where people've been digging, but you'll admit that whatever humans can do is absolutely minute compared to forces that can demolish hundreds of thousands of homes in a few minutes, or raise the Alps from the floor of an ocean.
There was quite a big quake in Folkestone a couple of years back. Caused £1000,000 worth of improvements.
I'll get me coat.
I've been having more of my crazy thoughts
Finally I can say I agree with you.
I want to investigate what's happening.....We all know that something is happening, I will stop mucking about and investigate this....[b]I don't want to do loads of research[/b]
you really are a confused individual aren't you
