Description:
In this paper we describe the results of a project
ongoing at the Istituto Nazionale di Geofisica e Vulcanologia
(INGV). The objective is to develop and implement a
system for monitoring and forecasting volcanic plumes of
Etna. Monitoring is based at present by multispectral infrared
measurements from the Spin Enhanced Visible and
Infrared Imager on board the Meteosat Second Generation
geosynchronous satellite, visual and thermal cameras, and
three radar disdrometers able to detect ash dispersal and fallout.
Forecasting is performed by using automatic procedures
for: i) downloading weather forecast data from meteorological
mesoscale models; ii) running models of tephra dispersal,
iii) plotting hazard maps of volcanic ash dispersal and deposition
for certain scenarios and, iv) publishing the results on
a web-site dedicated to the Italian Civil Protection. Simulations
are based on eruptive scenarios obtained by analysing
field data collected after the end of recent Etna eruptions.
Forecasting is, hence, supported by plume observations carried
out by the monitoring system. The system was tested on
some explosive events occurred during 2006 and 2007 successfully.
The potentiality use of monitoring and forecasting
Etna volcanic plumes, in a way to prevent threats to aviation
from volcanic ash, is finally discussed.
