Assessing minimum pyroclastic density current mass to impact critical infrastructures: example from Aso caldera (Japan)

Probabilistic PDC invasion maps for four sets of simulations (N=1000 each run) with different values of collapsing volume and vent positions sampled uniformly within Aso caldera. The other input parameters are derived from expert judgment. Dotted gray circles mark the positions of the five marker sites. Contour lines show the…

Quantifying the Statistical Relationships Between Flank Eruptions and Major Earthquakes at Mt. Etna Volcano (Italy)

Histograms of the interevent time of earthquakes and flank eruptions <4 months, including pie charts of the positive values (dark colors), negative values in [−2.5, 0] days (light colors), and lower than −2.5 days (white). (a, c, e) show the earthquakes with Ix ≥ V–VI EMS; (b, d, f) those with Ix ≥ VII–VIII EMS. (a,…

Physical and morphological characterization of the 19 May 2021 ash cloud deposit at Stromboli (Italy)

Photos (a),(b),(c) and (d) illustrate successive moments of the collapse and related PDC emplacement from the INGV thermal camera located at Punta dei Corvi, the SW side of the Sciara del Fuoco (SdF); the arrow indicates the NE craters, and the white dashed line indicates the shoreline. (a) represents the…

Global rates of subaerial volcanism on Earth

Papale P., D. Garg, W. MarzocchiFrontiers in Earth Science, https://doi.org/10.3389/feart.2022.922160 Abstract Knowledge of the global rates of volcanism is fundamental for modeling the Earth, as those rates closely relate to plate tectonics, crustal growth, mantle dynamics, atmospheric evolution, climate change, and virtually any aspect of the global…
