Two questions raised by Roger and Answers

Amit;

1) Can you show me an example of that? 2 quakes of equal mag and location.
Your cycle theory is simply wrong. The moon has nothing to do with quakes.
If it did, you would not have failed my long term test.

2) There are quakes not on plate boundaries but we do know why. Subduction zones for example.
Quakes related to volcanos for another.

Yes, your hits are due to chance. Otherwise you would not have failed my test.

Roger


AND  ANSWERS TO THOSE QUESTIONS


Roger 

OK, As you wish

1)As per plate tectonic theory, 7.5+ quake can occur at same location only after stresses built up again ,may be 50 years , 100 years , you specify 

now look at the following quakes

a)7.9 at 10.51 UTC,at 4.5 south and 153.2 East, on 17th December 2016...PNG

b) 7.9 at 4.30 UTC, at 6.24 South and 155.17 East on 22nd January 2017....PNG 

c)7.5 at 13.28 UTC at 6.7 south and 155 East on 19th April 2014....PNG

d)7.5 at 1.44 UTC at 5.46 South and 151.8 East on 5th May 2015.....PNG


e)7.5 at 12.58 UTC at 4.08 South and 152.56 East on 14th May 2019...PNG

Do you think 7.5+ quake equivalent stress can be accumulated in one month ?

How do you explain all these with plate tectonics ?

Ok next question

Look at the following quake
7.7 at Gujarat , India ( 23.4 North and 70.2 East) on 26th January 2001 at 3.16 UTC

Do you think there is volcano here
or plate boundary 
or Subduction Zone

How do you explain this 7.7 major quake

SO , think out of the box

Old theories are not necessarily correct especially when it says ,it is unable to predict major quakes

VERY GOOD! That's the sort of response I like to see.

The answer to the first part is that it depends on a lot of things we don't even know about.
Stress migrates around the plate boundary as it is possible, depending on the shape and distance to the next lock point. In faults like the San Andreas, relatively straight, it may be a long time while in areas like you mention it will be much shorter since the total stress is not released by one quake.

I don't know the geology of India so can't answer the next question.

Here's a test for you.

In the period 1973 to 2018 there were 6448 mag 6+ quakes in the NEC catalog.

That calculates out as 12.8 quakes per month or 1 every 2+ days.

So how can your 3 day windows miss so often?

We are talking about correctness of existing theory Plate tectonics.
Regarding my theory ,you have already given your opinion that it is useless
So ,let plate tectonics be correct first.
We will talk about ,what you believe correct and show how it is not correct or complete
Amit

Roger Hunter said...

Amit;

You may prove that I am wrong but that does not prove that you are right.

We may both be wrong and in fact, I have already shown that you ARE incorrect.

Roger

AMIT said...

Roger
I am sorry
Nothing personal.
We are taking about exesting plate Tectonic theory. It is nothing yours or mine
Amit

Roger Hunter said...

Amit;

No, you're right; this is not personal and I hope I have not offended you.

Roger

AMIT said...

Roger
Ok

we will not talk of existing plate tectonics ,since you say it may not be correct
Now for the test you have thrown open for me.....



Amit

Here's a test for you.

In the period 1973 to 2018 there were 6448 mag 6+ quakes in the NEC catalog.

So how can your 3 day windows miss so often?

Roger


This is because , 6+ quakes have a cluster on prone dates , they are not equally distributed ,so tat you can say 6+ quake every third day

Here is a proof

Take Japan quake of 9.5 on 11th March 2011

now between 10th March to 13 March 2011 , can you imagine how many 6+ quakes all over word

46

46 numbers of 6+ quakes in one window

There are 6+ quake spike and concentration on major quake day/prone dates

That is why taking average and saying there is one quake(6+) on third day is not correct

Amit

AMIT said...

Roger

sorry....typo mistake...
between 10th March to 12th March 2011

AMIT said...

Roger
Correct way,I think ,is...
to take one 6+ quake per three day window, even if ,there are more than one 6+ quake on given date
Amit

Watch out ,this is what may theory says

On the date when tidal pull is maximum , low tide and high tide both are extreme.
When it is high tide below crust it breaks open fault and hence quake
However ,when low tide below the crust there are splitting pull on fault and hence quake.
The reason shown here, water weight over crust is not correct.
Water weight of say 100 MTR is not compared to 100 km crust weight

Hello, you used to write excellent, but the last few posts have been kinda boring...
I miss your super writings. Past few posts are just a little bit out of track!

I rarely drop comments, but i did a few searching and wound up here "Two questions raised by Roger and Answers".

And I do have 2 questions for you if it's allright.
Is it only me or does it look as if like some of these comments come across like
coming from brain dead folks? :-P And, if you are writing on additional places, I'd like to keep up with
everything fresh you have to post. Could
you list of the complete urls of your communal sites like your linkedin profile, Facebook page or twitter
feed?
