Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 2. Probabilistic Invasion Maps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study presents a new method to assess the hazard of deposit‐derived pyroclastic density currents (PDC), a critical threat on volcanic islands and on populated slopes of active volcanoes, considering the exemplary case study of Stromboli (Italy).

Empirical Scaling Relationships Between Fault Length and Throw‐Rates Modulated by Fault Interactions in Extensional Regimes

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Throw rates of active faults are expected to scale with fault length because the geometric moment of a fault is directly related to its dimensions. However, empirical data sets commonly display substantial scatter, which limits the use of fault scaling relationships for seismic hazard assessment and for understanding the mechanics of ...

Surface ocean iron fertilization: the role of subduction zone and hotspot volcanic ash and fluxes into the Pacific Ocean [PDF]

, 2011
Surface ocean iron (Fe) fertilization can affect the marine primary productivity (MPP), thereby impacting on CO2 exchanges at the atmosphere-ocean interface and eventually on climate.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

Geomechanical rock properties of a basaltic volcano

Frontiers in Earth Science, 2015
In volcanic regions, reliable estimates of mechanical properties for specific volcanic events such as cyclic inflation-deflation cycles by magmatic intrusions, thermal stressing, and high temperatures are crucial for building accurate models of volcanic ...

Can the International Reference Ionosphere Model Predict Long‐Term Trends in the Ionosphere?

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The International Reference Ionosphere (IRI) model can partially reproduce ionospheric long‐term trends (LTTs), although not intentionally, provided that an appropriate effective ionospheric index is used. We evaluate how model predictions driven by a solar activity proxy (R12) and by an effective ionospheric proxy (IG12) can reproduce the ...

Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...

Crustal Heat Flow Drives the Earthquake Magnitude Distribution

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Earthquake magnitude‐frequency distributions exhibit significant space‐time variations, which can provide critical insights into the physical processes driving seismicity. Understanding these variations is crucial for assessing seismic hazards and uncovering the physical processes driving earthquakes.
