Schematic illustration of a series of numerical simulations of the two-layer PDC model. a A two-layer PDC is generated from the inlet boundary (x=0) and flows into a proximal inclined channel with length 9.68 m (slope angle θ=6∘) and into a distal horizontal channel (θ=0∘). b There are three interfaces,…

Infrasound waveforms recorded at Mt. Etna during July-August, 2019 and their spectrograms. Data are high-pass filtered (0.01 Hz) to remove the effect of long-period noise. (a) Ash explosion (~75–85 s) at the NEC; (b) Deep intra-crater gas explosions from BN; (c) Sequence of Strombolian explosions at the NSEC. De Angelis S., L.

Fig. 4. Stratigraphic constrained cluster analysis of selected calcareous nannofossils from core ND14Mbis for the 10.95–7.22 kyrs time interval, compared with lightness values (L*). Colour bands represent abundance values (%). Cascella A., S. Bonomo, F. Lirer, G. Margaritelli, H. Checa, I. Cacho, L. D. Pena, J. Frigola (2021).Global and Planetary…

Figure 1. Bathymetric map of the Ross Sea (modified from [24]). WAIS = West Antarctic Ice Sheet, EAIS = Eastern Antarctic Ice Sheet. The red rectangle indicates the studied area. HR = Hallett Ridge, BA = Bank A, BB = Bank B. Red dots indicate the studied box cores: BC02…

Global distribution of eruption volumes for VEI 0 – 8 eruptions. a) Distributions obtained by maintaining separation between eruptions belonging to different VEI classes. The red and orange symbols on one side, and the blue and green symbols on the other side, refer to data with only consistent, or…

FIGURE 1. Observed (∙) vs. simulated (∘) magnitude-intensity distribution. Observed data from the LaMEVE database (Crosweller et al. 2012; Brown et al. 2014; www2.bgs.ac.uk/vogripa/, accessed in February 2019). Magnitude and intensity as in Pyle (2015), also defined in the Methods. The space of variables has been sampled through a Latin…
