Letizia Spampinato BSc

PhD Student, supervised by Dr Clive Oppenheimer and Dr. Sonia Calvari, senior researcher at Istituto Nazionale di Geofisica e Vulcanologia, Catania, (Italy)

Application of thermal imaging to lava flow hazard assessment at Mt. Etna (Italy)

Biography

After I obtained my first degree in Earth Sciences in 2002, I took a research post at the Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Catania, joining the Volcanology and Geochemistry Group. Since November 2002, I have been applying thermal imaging to research and monitoring of the active volcanoes of southern Italy, (Mt Etna, Stromboli and Vulcano). The instrument used is a FLIR TM 695 thermal camera, and I have been able to study several eruptions including the 2002-03 eruptions at Stromboli and Mt. Etna. In addition, I also work with the Cartography Group of the INGV Catania Section, particularly during volcanic crises, when I assist with lava flow field mapping based on thermal images and digital photo interpretation.

Thermal image

The monitoring of active lava flow field evolution has become one of the main focuses of studies on basaltic volcanoes characterized by effusive activity. The evaluation of hazard and the simulation of lava flow paths are crucial to developing mitigation strategies to protect settled areas. Mt. Etna, for instance, with its frequent lava effusions from lateral vents has threatened towns, villages and tourist facilities several times. At the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Catania-Section, volcano surveillance is carried out by several different techniques, including the use of a TM 695 thermal imaging camera manufactured by FLIR. Infrared imaging surveys (handheld or tripod-mounted camera) conducted on Mt. Etna and also on Stromboli (Aeolian Islands, Italy) have enabled tracking of the development of lava flow fields and the collection of a large amount of data even when it was impossible to approach directly the active lava flows.

I will focus on infrared imagery collected during the 2002-3 eruption of Mt Etna with two main objectives: (i) to detect lava flow field spreading, and (ii) to discriminate lava flow field structures by mapping features such as lava tubes, which contribute to hazard because they promote the lengthening of lava flows (Calvari and Pinkerton, 1998). The study of lava flow field emplacement mechanisms and lava flow field structures is fundamental to assessment of lava flow invasion risk and its potential effects on land, property, and people. The techniques applied and developed, and the results obtained from this study of Etna, should be applicable to other basaltic volcanoes.
