Luciano Zuccarello has worked at the Istituto Nazionale di Geofisica e Vulcanologia (INGV-Sezione di Catania, Italy) since 2001. Since 2003, he has been responsible for the seismic mobile network of INGV-Sezione di Catania.

He has managed the deployment of multichannel and broad-band seismic networks at active areas worldwide, including: Etna, Stromboli, Vesuvio, Campi Flegrei, Panarea, Aquila (Italy), Teide (Canary Is., Spain), Fogo-Furnas (Sao Miguel Is., Azores, PT), Decepcion (Antarctica).

He participated in several European and Italian projects (e.g. e-Ruption (5th Framework Program – EVRI-2002-CT00421); TOMODEC, Deception Island, Antartica; VOLUME (6th Framework Program – Sustainable development, global change and ecosystems, FP6-2004-Global-3); DPC-V2, PAROXYSM Definition of expected precursors for major explosions, paroxysms and effusive eruptions at Stromboli volcano)).

His research interests are: (i) Array seismology on volcanoes. Wavefield composition, polarization analysis, source location of tremor, Long Period and Very Long Period seismic events, volcanic signals source processes; (ii) Seismological monitoring of active volcanoes; (iii) Cross-analysis of various geophysical signals; (iv) Analysis and source inversions of Very Long Period volcanic signals using numerical modelling of the waves propagation through a complex medium with topography.

In 2006 he began a PhD with the UCD Geophysics Group on volcano seismology




Research Interests

Project Title : Numerical modelling of seismic sources at Mount Etna, Sicily.

Supervisor(s): Prof. Christopher J. Bean and Dr. Saccorotti G.

Project Description: Detailed investigations on low-frequency signals from Mt Etna have been systematically carried out since the installation of the broadband network (late 2003), that allowed observation of sustained Long-Period (LP) and Very-Long-Period (VLP) activity during both quiescence periods and eruptive phases. The location of low frequency events provides hints on the extension and geometry of the shallow part of the plumbing system and establishes constraints for quantifying pressure transients and mass transport during the uprising of fluids along the feeding conduits. Therefore, this analysis represents a crucial step toward the quantification of mass budget during either quiescent or eruptive stages, towards a better volcano hazard evaluation. In particular, the source mechanisms of VLP events during the December 2005 - January 2006 period will be investigated, using full wavefield numerical simulations. During this period, an increase in the amplitude of the volcanic tremor was observed at Mt Etna, in almost total absence of eruptive activity. Green’s functions will be calculated at each station using a monodimensional velocity model and a three-dimensional discrete elastic lattice method, which takes into account the real topography. A Moment Tensor decomposition of the VLP source will be performed, using a frequency-domain, full-waveform inversion of the broad-band ground displacement recordings. Finally, the results will be compared with geochemical and geophysical data collected during the same period, with a view to improving our understanding of the relationships between VLP seismicity and volcanic activity at Mt Etna.
