Dear gadlen-ga;

Thank you for allowing me an opportunity to answer your interesting question.

I was able to find a couple of references to a TWO HUNDRED ton stone
being hurled a considerable distance by the Cotopaxi volcano:

"Solid bodies are thrown into the air with enormous force and to
proportionally great heights, those not projected vertically falling
in consequence at considerable distances from the volcano. A block
weighing 200 tons is said to have been thrown nine miles by Cotopaxi;
masses of rock weighing as much as twenty tons to have been ejected by
Mount Ararat in 1840; and stones to have been hurled to a distance of
thirty-six miles in other cases."

'The San Francisco Calamity '
http://www.bookrags.com/books/sfclm/PART19.htm

"In all great eruptions the flow of the lava is preceded by the
ejection of vast quantities of volcanic dust, ashes, dross, slag, and
loose stones. These are tossed into the air with tremendous violence,
consequently, to a great height. The stones thus ejected are sometimes
of immense size. A rock, whose weight is estimated at two hundred
tons, was thrown from the summit of Cotopaxi to the distance of more
than ten miles."

In 1907 Taal volcano in the Phils threw a 50 tonner 20 km away in a
garden, still on display. It's big as a truck.
