    Phase partitioning during fragmentation revealed by QEMSCAN Particle Mineralogical Analysis of volcanic ash

    Volcanic ash particle properties depend upon their genetic fragmentation processes. Here, we introduce QEMSCAN Particle Mineralogical Analysis (PMA) to quantify the phase distribution in ash samples collected ...

    Crystal plasticity as an indicator of the viscous-brittle transition in magmas

    Understanding the flow of multi-phase (melt, crystals and bubbles) magmas is of great importance for interpreting eruption dynamics. Here we report the first observation of crystal plasticity, identified using...

    The permeability of fractured rocks in pressurised volcanic and geothermal systems

    The connectivity of rocks’ porous structure and the presence of fractures influence the transfer of fluids in the Earth’s crust. Here, we employed laboratory experiments to measure the influence of macro-fract...

    Volcanic drumbeat seismicity caused by stick-slip motion and magmatic frictional melting

    During volcanic eruptions, solidifying magma ascends through the volcanic conduit, often accompanied by repetitive, drum-beat seismicity. Laboratory experiments on magma samples from Soufrière Hills Volcano, M...
