  • Fragmentation-induced fluidization occurs in concentrated pyroclastic density currents where rapid particle breakage causes flow compaction and subsequent high pore fluid pressure, reducing friction and explaining their long runout.

  • Pyroclastic density currents are able to travel large distances because they generate their own air lubrication, according to large-scale laboratory experiments.

  • Liquid electrolytes in batteries are considered to be macroscopically homogeneous ionic transport media despite having a complex chemical composition and atomistic solvation structures. A micelle-like structure in a localized high-concentration electrolyte for which the solvent acts as a surfactant is reported.

  • The hazards of pyroclastic surges remain poorly mitigated globally. Here, the authors show that their destructiveness is amplified by turbulent excursions of dynamic pressure energy that focusses inside the largest eddies and internal gravity waves.

  • Lithium metal is considered an ideal anode for high-energy rechargeable lithium batteries, but understanding its nucleation and growth at the nanoscale remains challenging. Using cryogenic transmission electron microscopy and simulations, a structural and morphological evolution scenario for Li deposits is proposed.

  • Pyroclastic density currents are complex multiphase flows originating from volcanic eruptions and account for almost a third of volcanic fatalities globally. This Review discusses recent advances in understanding of the complex internal processes within pyroclastic density currents and how these influence the flow dynamics and hazard footprints.
