Cover Story: Hydrovolcanism is a type of volcanism where magma and water interact either explosively or non-explosively. Hydrovolcanism is commonly used as a synonym for phreatomagmatism. However, recently, phreatomagmatism has appeared more in association with volcanism that occurs in shallow subaqueous or terrestrial settings. Here, a revised and reviewed classification scheme is suggested for hydrovolcanism with special reference to its explosive varieties, based on their geo-environment in which magma–water interaction takes place and explosivity plus mode of energy transfer are required to generate kinetic energy to produce pyroclasts. Explosive hydrovolcanism is discussed here from a field context, from the perspective of monogenetic volcanism. View this paper

Late Quaternary Tectonic Activity of the Udine-Buttrio Thrust, Friulian Plain, NE Italy

  • Andrea Viscolani,
  • Christoph Grützner,
  • Manuel Diercks,
  • Klaus Reicherter and
  • Kamil Ustaszewski

The NW-SE trending Udine-Buttrio Thrust is a partly blind fault that affects the Friulian plain southeast of Udine in NE Italy. It is part of a wider fault system that accommodates the northward motion of the Adriatic plate. Although seismic reflecti...

Design Strategies to Mitigate Slope Instabilities in Structurally Complex Formations

  • Paolo Ruggeri,
  • Viviene M. E. Fruzzetti and
  • Giuseppe Scarpelli

Stiff jointed clays (SJC) belong to so-called structurally complex formations in which the macroscale features of the deposit, that is the pattern of discontinuities affecting the soil mass, influence its response at the scale of engineering works. S...
