Wrong. You are confusing scale with cause.
And you won't learn cause.

If a quake is caused by a plume rising from subducted material it will
tend to cause more stress relief in the same way as opening a can of
pop will release more than one bubble.

Not only that but it will bring the windypops up from all over the
planet.

For a remarkable weather barometer for earthquakes you would do well
to follow the charts on here:

When a Lows system leaves one of the continents it has to break
through the anticylone blet to get to the Arctic.

Why it has to do that when it could get rid of its energy by mixing
then and ther and why it then has to go to the Antarctic continent
each and every time for all three continents supplying the cyclonic
masses sis a demonstration of the wave effect of weather.

Once it reaches the Antarctic hit has to rise the three or so miles of
dome the continent comprises.

Rising in that temperature it loses its cyclonic identity and would
become and High instead of a Low.

But wave physics isn't like that. What happens instead is that the
wave goes underground. How and the rest of it I do not yet know.

Observe the action when one of those dark patches reaches a bay such
as the Ross Ice Shelf as it did with that mag 7 recently.

Yes.
And no.

It takes a great deal of energy out of the system to produce a quake
of that magnitude.

Also the enrgy involved is related to storms that rach cyclosis some
80 degrees from the epicentre. This rarely happens in most places
because large storm are generally confined to so few regions. However
this is a remarkable wea5her spell the equale to that of 1947 and
1963.

Earthquakes occur in aquifers several miles down. The pressure and
temperature has to be enough to dissolve rock. The tidal nature of
earthquake and wave physics does the rest.

You will notice that mountain building isn't incremental but they are
shoved up out of the ground several meters at a time according to the
severity of the quake.

Another statistic in the favour of plate tech being the work of fools
is that most quakes are in the mounts not the trenches, almost always
along the same stretch of coast measured from the shelf height.

***

One more thing, you being a citizen of eastern Canada:

You will notice the behaviour of the MetO North Atlantic chart
corresponds with the occurrence of quakes. Currently it is also
showing its relationship with tornadic cells.

When one of your Lows passes through a Greenland High and almost any
other High to the east of it, there is a tendency for tornadoes -as
shown in the tornado reports charts from NWS.
