Unfortunately, you never spelled out what you imagined.
Quite the contrary: you ducked a question which would have enabled
you to clearly state what you imagined.

You never explain this "Unfortunately." Instead you indulge in a
shell game below, substituting "evidence of subduction" for
"direct observation of subduction" and thereby creating a false
virtual reality of "naivete" about me.

Why did you not SAY what you meant instead of using misleading words
like "with actual eyes"?

So you think it is NOT evidence for subduction????
No, you are indulging in misleading language which tends to create the
impression that I think it is the ONLY evidence for subduction.
And you know that I think nothing of the sort.
And you keep doing it below, so my next comment will be more forceful
as a result.

It does nothing of the sort, and you are not describing even one
example of this alleged naivete.
You are disingenously substituting "evidence of suduction" for
"direct observation of subuction." Once this is obvious, your
entire case for naivete on my part collapses.

Unfortunately, you still haven't answered this question, preferring
to try an pick a fight with me by making unsupported accusations
of naivete.

Let's see you try and explain why, taking into account what I wrote
about filming of slippage along e.g. the San Andreas fault.
If you can't do better than your inept attempt below,
the logical inference is that you didn't answer my
question at first because it took you several hours to dream
up this unsupported retort.

I wouldn't use the word "volcanoes" for that.

That's up to YOU to tell ME. Can't you even figure out why
I was asking "Why even mention volcanoes?"

What part of "shifting of oceanic crust" didn't you understand?

"quite local" -- why don't you QUANTIFY that? Do you think cameras
spaced ten miles apart would miss all the slippage from MAJOR
earthquakes? It would take less than a hundred such cameras to
monitor the whole visible part of the San Andreas fault.
Your use of the singular "camera" suggests extreme naivete on
YOUR part, whereas you have yet to quote as single statement by
me that is anywhere near as naive.

Are you suggesting that the Marianas Trench is actually a whole
conglomerate of parallel short trenches, and that subduction
could occur along only a few of them during a 9 point earthquake?
If so, I'd like to see some documentation for it.

I did. And you've responded. Cryptically, in defiance of your
alleged desire for expediting things:

Perhaps you should stop accusing me of naivete and then never
identifying anything that indicates naivete.
That would make it unnecessary for Oxyaena, Simpson, and Howler
Monkey to try and make you out to be my innocent victim, as they
are doing now.
Because then we would have a mature adult conversation.

No, I was not. It was you who were unclear with the misleading

You kept asking insulting questions instead of helpfully trying
to tell me why you think it is impossible to have direct instrumental
observation of subduction.

...at present. But you are still dragging your feet as far as
explaining why you are thoroughly convinced that there will
never be a visual record of subduction:
"it's not something you could get movies of."
-- Harshman, way up there where Oxyaena and Simpson
and Howler Monkey can pretend they never saw it.
