To think all these earthquakes are strange??

[Mammylamb]

Recently there seems to have been a lot of earthquakes (Japan, nz, Mexico). Is it normal to get so many close together in time? (admittedly thousands of miles apart)

I have lived on this planet for 50 years and a number of days.

There have been many times that have felt a bit 'end of the earthy'.

I agree now is probably one of those times, but I am so over it. It has happened so many time through my life, I have learnt to calm down an realise it probably really is not the end!

Also, I am too busy just getting on with life to give a shit!

Most people live in denial - the masses.

Yes, there is definitely something going on.

Mother Earth is angry because we do not respect her.

But we are going into the 5th Dimension so lots of shit before that (to work things out) and lots of people checking out beforehand. Their choice. They need to work out their stuff on another dimension.

NZ has countless earthquakes/tremors/aftershocks every day, most of them just aren't felt by people. The whole country sits on fault lines, so is prone to them. The same goes for Japan.

Recent devastating earthquakes in Haiti, Chile and China, as well as magnitude 7+ earthquakes in Indonesia and California, might give the impression that earthquake activity is increasing.

In fact, a quick look at earthquake statistics over the last 20 years shows that this is not the case.

On average there are about 15 earthquakes every year with a magnitude of 7 or greater.

As with any almost random phenomena, the number of earthquakes each year varies slightly from this average, but in general, there are no dramatic variations.

So far this year, there have been six magnitude 7+ earthquakes, in keeping with the annual rate.
Energy budget

Earthquake activity is controlled by the motion of the Earth's tectonic plates, driven by heat generation from the decay of radioactive elements deep inside our planet. Thermodynamics requires that for more energy to come out of a system, more energy has to go in.

A long term increase in earthquake activity would require an increase in the Earth's internal energy supply, which would be difficult to account for.

This is why all your children need to study geography at school (biased geography teacher here) the most relevant and interesting subject around (yep biased but I believe it!)
Guess what I've been talking about today at work!

Probably a statistical blip.

Or it could be that they are somewhat linked, as the plates that form the Earth's crust are also linked. So, it could be that one adjustment is followed by other re-adjustments.

It's also possible that the large hurricanes and water displacement have had some impact. Butterfly effect and all that.

Still, I wouldn't worry.

For all you religious pet lovers-

Help is at hand.

As an atheist I run a post rapture pet rescue service.
One easy up front payment is all it takes.

I've pondered whether numerous underground nuclear tests have any impact. I know this sounds a bit crazy and I'm aware of plate tectonics etc but all that energy has to do some damage surely? And I know that earthquakes have always existed, as have hurricanes, but it does seem like mother nature is intent on making a strong point lately.

GladAllOver - and your point?

Of course there has always been earthquakes/hurricanes etc. I belivevI said that?

But - all weather records since they began about 250 years ago have been broken within the last 20 years or so.

And you think that's worth ignoring?

Well done.

And I would worry.

Not for this year or next - but for our children and grandchildren.

And I repeat - I'm no doom and gloom merchant. Absolutely not.

I'm just a someone who thinks ahead and reads.

The numerous tests were in the 78's and 80's (after atmospheric ones were banned)
There have been sod all tests for the last 20 years

Oh, and by the way I'm an atheist.

I read about science.

My responce of choice here would be to call the Winchester 😂

Winchesters even, though we could all go to the Winchester, have a pint and wait for it all to blow over as well.

I think ones just gone off in Japan, unless that was yesterday.

San Andreas fault hasn't let of a big quake in a while - it's due- especially with all the Mexico ones along the southern plate edge.

Ta1kinpeece NK detonated the largest one for a very long time a short while ago and a tunnel collapse was registered shortly afterwards.... This was the latest in a series of about 7 in the last decade.

Except in North Korea.

But, there's fracking.

And hurricane Irma was detected by seismographs.

Maybe because there have been small ones.

Jimmy Kimmel talked on his show about a recent one shortly after the Mexican quake.

I read somewhere that with Donald Trump saying climate change is bollocks, it's like climate change has said to someone 'is that right? Here, hold my drink'

in the 50's 60's and 70's the USA and the USSR were popping off one a week each
and the North Korean one is piddy compared with some of the big early ones

seriously
Kim is massively over hyped

PS The Korean test was around
100 kilotonnes (100,000 tonnes equivalent)
the biggest USSR atmospheric test was
50 megatonnes (50,000,000 tonnes equivalent

I'm not I remember that 84 earthquake!! Or tremor I guess we should say. I was washing my face and trying water splashed around in the sink!! (I never knew it was the miners' fault though )

You are thinking in human timescales. You think our current weather is extreme but what about the ice age? That must have set a few records! In geological terms the ice age is a recent event. The last glacial period only ended 10,000 years ago.
