  • Insights into the dynamics of the Nirano Mud Volcano through seismic characterization of drumbeat signals and V/H analysis 
    Antunes, Verónica; Planès, Thomas; Obermann, Anne; Panzera, Francesco; D'Amico, Sebastiano; Mazzini, Adriano; Sciarra, Alessandra; Ricci, Tullio; Lupi, Matteo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Mud volcanoes are rapidly-evolving geological phenomena characterized by the surface expulsion of sediments and fluids from over-pressurized underlying reservoirs. We investigate the Nirano Mud Volcano, Northern Italy, ...
  • Lusi, a clastic-dominated geysering system in Indonesia recently explored by surface and subsurface observations 
    Karyono, Karyono; Obermann, Anne; Lupi, Matteo; Masturyono, Masturyono; Hadi, Soffian; Syafri, Ildrem; Abdurrokhim, Abdurrokhim; Mazzini, Adriano (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The spectacular eruption of Lusi began in NE Java, Indonesia, on 29 May 2006 and is still ongoing. Since its birth, Lusi has presented a pulsating activity marked by frequent eruptions of gas, water, mud and clasts. The ...
  • The plumbing system feeding the Lusi eruption revealed by ambient noise tomography 
    Fallahi, Mohammad Javad; Obermann, Anne; Lupi, Matteo; Karyono, Karyono; Mazzini, Adriano (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Lusi is a sediment‐hosted hydrothermal system featuring clastic‐dominated geyser‐like eruption behavior in East Java, Indonesia. We use 10 months of ambient seismic noise cross correlations from 30 temporary seismic stations ...
  • Seismicity at Lusi and the adjacent volcanic complex, Java, Indonesia 
    Obermann, Anne; Karyono, Karyono; Diehl, T; Lupi, Matteo; Mazzini, Adriano (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    We study the local seismicity in East Java around the Arjuno-Welirang volcanic complex that is connected via the Watukosek Fault System, to the spectacular Lusi eruption site. Lusi is a sediment-hosted hydrothermal system ...
