| 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. |
