..I simply compared together 20 strongest earthquakes in recorded history with Moon distance, and discovered that Moon position in that time is totally random..

Yes I've always agreed that a near moon has no more noticeable an effect than a far moon..:)
Go read up on 'The Roche Limit' which explains how two bodies can be torn apart by each others gravity if they get too close to each other.
That won't happen with the Earth-Moon because they're too far away from each other, but the moon still exerts enough gravitational tug on the Earth to trigger--not cause-- earthquakes.
 
Roche limit is something else....It is related to this stuff, but it does not play any role.
Best example for triggering earthquakes because of tidal forces is Jupiter - Europa or Jupiter - Io system. Those are school examples how gravity of one large body can affect another one. But that's not the case with Earth - Moon system. Simply, Moon gravity is not strong enough to affect earth surface on that way.
Tides can be observed because that tiny force affects huge surface, and that's all.

Anyway, like i said before, all major earthquakes are not connected to the Moon distance :)

Like I said twice before, I agree with you about distance..:)
But I've moved on to gravity gradients which is a different thing. Google around and you'll see that the moons pull buckles the earths crust by about 16 inches a day, and if two plates are jammed against each other that can be enough to jog them and make them jump and release their pent up energy and cause a quake.
 
Ha ha perhaps we have a language problem here, so let me ask you a simple question-
We know the moons gravity creates a tidal bulge that causes the tides, but does the moons gravity also create a 'tidal bulge' in the earths solid crust?
 
Yes, but those are measured in micrometers.
So, answer is - no.
 
Ha ha you're a funny guy, you answer both 'yes' and 'no'.
In Britain we call that 'hedging our bets'..:)
 
It's not yes or not.
If question is "Can Moon trigger quakes by it's gravity?" Answer is no.
If it's "Does Moon affect solid ground?" Answer is yes, but it's barely measurable.

Good, you now admit the moon affects the earths crust, so we're making progress..:)
As for how measurable it is, i've seen quotes of "25 centimetres" at some websites, but scientists are not certain.
But now that you, me and scientists all agree that the moon affects the crust, it's only logical to assume that this very slight effect might trigger the release of pent up energy in the crust to produce earthquakes..:)

"These horizontal forces cause rock and water to feel a gravitational force which results in the flow of rock and water into the 'tidal bulges'"

Here are the more pressing questions!:doh:

No scientist would agree about that. That effect you are talking about is negligible.
Moon does not trigger earthquakes.
 
@205
Why silence?
Maybe there is nothign to say.

Where are updates?
They are on NASA website and all other sites that are tracking NEOs.
 
Not only does the moon buckle the earths crust but it does strange things to people-

Ive told all my mates there is gonna be an earthquake on 26/27th September. Either they will think Im a fruit loop or a bloody prophet... LOL

Well, since we all know your a fruit loop, that leaves a prophet...:hail:

Having lived in California for so many years, earthquakes instill fear in me, only when Im in a city. Since I moved to Ar-kansas, real fear comes in the form of tornadoes no matter where I am. Especially the ones that come in the night.
 
our problems here are Tornado's and yankees moving down here bringing their violence, crime, traffic and STD's. (quote from dear mother in law)

I am often at fault but live nowhere near one. Being estrogen impaired, I am ready to be faulty but not plate tech tonically.
 
And here is table showing moon distance and strongest quakes:

columns description:
per - perihelion distance for that month (km)
per date - perihelion date for that earthquake
apo, apo date - same for apogee
max columns - maximum values for that year

So, i believe that POS and scientist now can point us how does Moon affects quakes.
