The April issue of Weather has a review of a book about the Tambora
eruption. In the review, it says that the "eruption was bigger by at
least one order of magnitude than any before it." Should he have
added something on the lines of "except for the mystery eruption
that occurred only seven years earlier which may have been as big
and had a greater effect on the climate"?

Where is the evidence for this earlier volcanic action? It should
have left a sizeable hole somewhere or a bunch of fresh lava and ash
fields. A caldera forming volcanic explosion is difficult to hide!

I remain puzzled why Tambora did not precipitate a display of winter
nacreous clouds at temperate latitudes in the same way that Krakatoa
did for a couple years following its less significant eruption.


It appears to have occurred near the beginning of December 1808.

If there wasn't such a violent eruption then one must assume that the
atmosphere anticipated the Tambora eruption by half-a-dozen years or
more. Unlikely, I think. ;-)
