Journal ArticleDOI
Magmatic Gas Composition Reveals the Source Depth of Slug-Driven Strombolian Explosive Activity
Mike Burton,Mike Burton,Mike Burton,Patrick Allard,Patrick Allard,Patrick Allard,F. Murè,F. Murè,F. Murè,Alessandro La Spina,Alessandro La Spina,Alessandro La Spina +11 more
TL;DR: Spectroscopic measurements performed during both quiescent degassing and explosions on Stromboli volcano are used to demonstrate that gas slugs originate from as deep as the volcano-crust interface (∼3 kilometers), where both structural discontinuities and differential bubble-rise speed can promote slug coalescence.
Book ChapterDOI
Crater Gas Emissions and the Magma Feeding System of Stromboli Volcano
Patrick Allard,Alessandro Aiuppa,Mike Burton,Tommaso Caltabiano,Cinzia Federico,Giuseppe Salerno,Alessandro La Spina +6 more
TL;DR: In this paper, the chemical composition and mass output of these crater emissions (gases, trace metals, radioactive isotopes) were measured using different methodologies: within-plume airborne measurements, ground-based plume filtering, and/or in situ analysis, remote UV and open-path Fourier transform infrared absorption spectroscopy.
Journal ArticleDOI
Open-path FTIR spectroscopy of magma degassing processes during eight lava fountains on Mount Etna
Alessandro La Spina,Mike Burton,Patrick Allard,Patrick Allard,Salvatore Alparone,Filippo Murè +5 more
TL;DR: In this article, a series of 16 discrete lava fountain paroxysms occurred at the Southeast summit crater (SEC) of Mount Etna, preceding a 28-day long violent flank eruption.
OtherDOI
Patterns of bubble bursting and weak explosive activity in an active lava lake—Halema‘uma‘u, Kīlauea, 2015
Bianca G. Mintz,Bruce F. Houghton,Edward W. Llewellin,Tim R. Orr,Jacopo Taddeucci,Rebecca J. Carey,Ulrich Kueppers,Damien Gaudin,Matthew R. Patrick,Mike Burton,Piergiorgio Scarlato,Alessandro La Spina +11 more
TL;DR: In this article, the authors propose a method to solve the problem of homonymity in homonym identification, i.e., homonym-of-individuals-with-groups.
Journal ArticleDOI
Aerosol Optical Properties of Pacaya Volcano Plume Measured with a Portable Sun-Photometer
TL;DR: In this paper, Sun-photometer multichannel measurements of aerosol optical depths (AODs) in the visible and near-infrared spectral ranges, and Angstrom parameters of the plume issued from the Pacaya volcano, Guatemala, are presented for the first time.
