DOI: 10.1002/2017jb014683
Abstract: In this study, we collected samples from subaerial basaltic glassy margins from the second Hawaii Scientific Drilling Project (HSDP2) core. We employed the rigorous ‘IZZI’ method during the paleointensity experiment combined with the stringent ‘CCRIT’… read more here.

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.

Chemical variability in peralkaline magmas and magma reservoirs: insights from the Khaggiar lava flow, Pantelleria, Italy

DOI: 10.1007/s00410-020-01678-0
Abstract: Silicic volcanoes are increasingly understood to be underlain by crystal-rich and vertically extensive magma reservoirs within which disequilibrium is widespread. Observations from ignimbrite deposits demonstrate that silicic magma reservoirs are often compartmentalised and compositionally stratified.… 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/s00445-018-1192-6
Abstract: During an eruption, time scales of topographic change are fast and involve vertical and planimetric evolution of millimeters to meters as the event progresses. Repeat production of high spatial resolution terrain models of lava flow… read more here.

DOI: 10.1007/s12040-020-01418-9
Abstract: The crust is a vesicular layer that caps the compact core of sheet lava flows. We describe for the first time, a crust composed of multiple layers (each distinguished by a chilled glassy rind) from… 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.

DOI: 10.1016/j.jsames.2017.04.014
Abstract: Abstract The understanding of the paleosecular variations (PSV) of the geomagnetic field in South America is still biased by the scarcity of data. Especially, the recent geomagnetic PSV is characterized by the large growth of… read more here.
