232 Earthquakes in Sicily. 
explosions fron the burning mountain. St. Marco suffered 
exceedingly, but Naso was entirely destroyed.* e vol- 
canoes of Kolie contributed much to the earthquakes of Ca- 
Jabria and Messina in 1783. Stromboli was almost always in 
great commotion. For many days it seemed like a mad bull, 
which, raised above the waves, by his roaring filled Calabria 
and Sicily with terror. Vulcano often accompanied it, and 
its deep rumblings, and vast columns of smoke and flame, 
were terrible. 
After the violent earthquake of Sciacca in 1816, the same 
evil fortune happened to other parts of the island. On the 
15th of April, 1817, a severe shock terrified the people of 
Caltagirone in Valdinoto, and of the neighbouring places. 
One happened at Catania in October, and another on the 
20th of February of the following year, 1818, which was 
enormous. All the towns about Atna were ruined, and many 
lives lost. Catania felt its injurious effects. It was felt all 
over the island, since at Palermo it produced three undula- 
tions. Others which followed it, and which continued to

cinity enjoyed repose until the Sth of September, when all 
Madonia was convulsed. Other shocks succeeded in Oc- 
tober and November. On the 25th of February, 1819, a very 
severe one was felt, which extended to agreat distance. At 
Palermo three motions were produced, the last of which was 
very violent. The shocks in the whole of the vast extent of 
the mountains, where so much injury was done to the houses 
of the numerous inhabitants of these regions, were always 
receded and followed by subterranean murmurs, and distant 
explosions. Under these places it seems that those sub- 
stances were deposited, which tna inflamed and ejected 
from its mouth in the fellowing May; because after the erup- 
tion commenced, Madonia was left in quiet; while #tna,
