- Abstract
- Focusing on the Island of Stromboli, this research investigates whether airborne remote sensing systems,
such as those based on digital photogrammetry and laser scanner sensors, can be adopted to monitor slope
deformation and lava emplacement processes in active volcanic areas. Thanks to the capability of extracting
accurate topographic data and working on flexible time schedules, these methods can be used to constrain
the regular and more frequent measurements derived from satellite observations. This work is dedicated to
the monitoring of Stromboli's volcanic edifice which is beneficial when obtaining quantitative data on the
geometry of deformation features and the displaced (failures and landslides) and emplaced (lava flows)
volumes. In particular, we focus on the capability of extracting average effusion rates from volume
measurements that can be used to validate or integrate satellite-derived estimates.
Since 2001, a number of airborne remote sensing surveys, namely Digital Photogrammetry (DP) and Airborne
Laser Scanning (ALS), have been carried out on Stromboli's volcano to obtain high resolution Digital Elevation
Models (DEM) and orthophotos with sub-meter spatial resolution and a time schedule suitable for monitoring
the morphological evolution of the surface during the quiescent phases. During the last two effusive eruptions
(20022003 and 2007) the surface modifications, created on the Sciara del Fuoco slope and on the crater area
as a consequence of effusive activity, were quantified and monitored using the same methodologies. Thiswork,
which is based on the results obtained from the multi-temporal quantitative analysis of the data collected from
2001 to 2007, mainly focuses on the 2007 eruption but also accounts for analogies and differences regarding
the 20022003 event. The 2007 eruption on the Sciara del Fuoco slope from 27 February until 2 April, produced
a compound lava field including a lava delta on the shoreline, discharging most of the lava into the sea. The
comparison of the 2007 DEMs with a pre-eruption surface (2006 LIDAR survey) allowed for the evaluation of
the total lava volume that accumulated on the subaerial slope while two syn-eruption DEMs were used to
calculate the average effusion rates during the eruption. Since the evolution of a lava field produced during an
eruption can be seen as a proxy for the magma intrusion mechanism, hypotheses are formulated on the
connection between the lava discharge and the instabilities suffered by the slope. (literal)
