[b-hebrew] Thera quote

I am familiar with the quote.

The geographic distribution of the ash is a given.  We know exactly what
that is.  Clearly ash went much more and farther in one direction than the
toher - and in the farther direction it travelled far indeed.

The quote attempts to guess what time of year the eruption occurred at by
explaining the prevailing weather pattern.    I don't think one could
guarantee there wasn't a gale at a funny time of year or whatever, but it
basically makes sense to me.

This the wrong reasoning. Of course that for the Theran outbursts not having
reachead higher strata  would the direction of the wind at the time of the
outburst be important and would redirect them. These "low" outbursts would
also according to the laws of ballistic be also the shortest in the reach of
the volcano. Such ones under the correct angle and powerfull enough to reach
higher strata would be completely independent of the winds and reach more
remote regions.

So what happened on Melos is typical for a "low" shot. The rest depends om
the volcano itself.
