DOI: 10.1002/esp.4284
Abstract: The age of past lava flows is crucial information for evaluating the hazards and risks posed by effusive volcanoes, but traditional dating methods are expensive and time-consuming. This study proposes an alternative statistical dating method… read more here.

DOI: 10.1007/s00445-017-1176-y
Abstract: Thermokarst terrains develop when ice-bearing permafrost melts and causes the overlying surface to subside or collapse. This process occurs widely throughout Arctic regions due to environmental and climatological factors, but can also be induced by… read more here.

DOI: 10.1007/s00445-019-1309-6
Abstract: Lava emplacement at monogenetic volcanoes has been seldom documented when compared to persistently active volcanoes such as Mt. Etna or Kilauea. To expand the scientific understanding of lava emplacement, and to help assess the hazards… read more here.

DOI: 10.1007/s12040-019-1208-4
Abstract: The Deccan trap basaltic lava flows host a plethora of secondary minerals, notably zeolites, quartz and calcite. These minerals occupy the vesicles and cavities that are formed during the solidification of the lava flows. Much… read more here.

DOI: 10.1016/j.epsl.2020.116163
Abstract: Abstract We document remarkably efficient thermo-mechanical erosion by a small-volume lava flow. Downcutting by a basaltic-andesite lava flow on the steep-sided Momotombo volcano, Nicaragua, occurred at 100 times the rate commonly reported for thermal erosion… read more here.
