Hydrovolcanic tuff rings and cones as indicators for phreatomagmatic explosive eruptions on Mars [PDF]
Journal of Geophysical Research: Planets, 2013 AbstractHydrovolcanism is a common natural phenomenon on Earth and should be common on Mars, too, since its surface shows widespread evidence for volcanism and near‐surface water. We investigate fields of pitted cones in the Nephentes/Amenthes region at the southern margin of the ancient impact basin, Utopia, which were previously interpreted as mud ...

Internal vs. external forcing in shallow marine diatreme formation: a case study from the Iblean Mountains (SE-Siciliy, Central Mediterranean) [PDF]
, 2009 A model of diatreme evolution in a shallow marine setting is based on a multi-disciplinary analysis of diatremes in the Iblean Mountains (Sicily). The approach includes stratigraphic, volcanological, structural, petrologic and compositional data.

TSUNAMI GENERATION DUE TO SUBMARINE VOLCANIC ERUPTIONS WITH PHREATOMAGMATIC EXPLOSION OR CALDERA SUBSIDENCE [PDF]
Coastal Engineering Proceedings, 2014 An index of submarine volcanic explosivity concerning tsunami generation has been proposed on the basis of the relationship between phreatomagmatic explosion and resultant initial waveform of tsunamis. In the generation process of tsunamis due to phreatomagmatic explosion, the seawater touches magma of high temperature, after which the water evaporates
