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

One of the possibilities to prevent building pounding between two adjacent structures is to consider appropriate in-between separation distance. Another approach might be focused on controlling the relative displacements during seismic excitations. A...

2D Runout Modelling of Hillslope Debris Flows, Based on Well-Documented Events in Switzerland

  • Florian Zimmermann,
  • Brian W. McArdell,
  • Christian Rickli and
  • Christian Scheidl

In mountain areas, mass movements, such as hillslope debris flows, pose a serious threat to people and infrastructure, although size and runout distances are often smaller than those of debris avalanches or in-channel-based processes like debris floo...

  • Cédric H. David

As drought occurs in a region it can have cascading effects through the water cycle. In this study, we explore the temporal co-evolution of various components of the hydrologic cycle in California from 2002 to 2018. We combine information from the Gr...

The distinction between turbidites, contourites and hemipelagites in modern and ancient deep-water systems has long been a matter of controversy. This is partly because the processes themselves show a degree of overlap as part of a continuum, so that...

To understand the time evolutions of frontal speed and shape in a low-density granular flow, we propose a simple particle model. This model solves the equation of motion for each particle and simulates the time evolution of low-density granular flow....
