Abstract
Since 1979 explosive activity of Etna produced
many short-lived ash-plume forming eruptions that
created several problems to the operations of
Catania and Reggia Calabria airports. In 2001 and
2002 a prolonged explosive activity caused
continuous tephra injection in the atmosphere for
several weeks. Lapilli and ash blanketed the
volcano slopes down to Catania airport 35 km far
from the vent, and fine particles reached
hundreds of km of distance up to the northern Africa
coast. The effects have been very serious
disrupting the Catania airport operations for many
days during three months as never was happened in
Italy since the last Vesuvius eruption occurred in 1944.
Italian Institute of Geophysics and
Volcanology (INGV) is in charged for
monitoring the eruptive phenomena of Etna
volcano. It have to furnish to Catania
International Airport Direction, Italian
Agency for Civil Aviation (ENAC) and Italian
National Civil Protection data on ash cloud
dispersion on Sicilian airspace and on ash
fallout on Catania airport. To put in operation
one efficient ash-cloud monitoring system we
will use the remote sensing IR images
transmitted in real time by MSG satellite
and by o network of ground-based IR
cameras observing the volcano summit.
