ometres, (2-1/2 miles) from the summit of Etna. To the
west of, and somewhat above the principal crater, a second one was
formed, but its activity was of short duration. The liquid lava issued
with such violence that in 24 hours it had reached the base of Monte
Calanna, a distance of 3 kilometres, (nearly 2 miles). After surrounding
this hill, it divided into two currents, one of which ran towards
Zaffarana, and the other towards Milo. At a distance they seemed to
present a united front of 2 kilometres, (1-1/4 mile), which threatened
to destroy all the villages below. The Val del Bove was already
entirely overrun; Isoletta dei Zappinelli in the midst of the lavas of
1811 and 1819 was overwhelmed; the valley of Calanna was buried under
the fire with lava, when on the 28th of August the lava hurled itself
into the narrow passage of the Portella di Calanna. A frightful cascade
of lava was then seen to precipitate itself from a height of 60 metres,
with a harsh metallic noise, accompanied by loud cracking. Zaffarana was
on the eve of total ruin; the fire had taken the direction of the ravine
which terminates there, when suddenly, in the beginning of September,
the devastating stream stayed its march against the ill-fated district.
On the contrary that which had taken the direction of Milo, reinforced
by a new current on the 10th of September, destroyed the hamlet of
Caselle del Milo; and afterwards divided itself into two branches, which
left the village of Caselle in safety between them.
The inhabitants of La Macchia and Giarre gave themselves up for lost;
for it seemed that the lava would be obliged to follow the valley of
Santa Maria della Strada; happily, however, from the 20th of September
onward, it ceased to advance perceptibly. The eruption did not totally
subside till March 1853; but the lava-flows did no more than travel by
the side, or on the top of the older, without extending beyond them.
The crater of 1852 was called the Centenario, from its having been
formed at the time of the centenary of the fete of S. Agatha. Santiago,
in the island of Cuba, was destroyed by an earthquake on the very day of
the eruption.
During the whole period of the eruption, only one explosion proceeded
from the great crater of Etna. By it an enormous column of ashes and
scoriae was cast into the air.
On the 9th of September white ashes were seen on the summit, which at a
distance appeared like snow. When pressed together by t
