This work deals with a comprehensive multiparametric and multilayer approach to study
earthquake-related processes that occur during the preparation phase of a large …

On 20 December 2021, after six quiet years, the Hunga Tonga–Hunga Ha'apai volcano
erupted abruptly. Then, on 15 January 2022, the largest eruption produced a plume well …

In this paper, we present a detailed study of the effects of the interplanetary magnetic field
(IMF) strength on the foreshock properties at small and large scales. Two simulation runs …

The Tonga-Kermadec subduction zone represents one of the most active areas from both
seismic and volcanic points of view. Recently, two planetary-scale geophysical events took …

Regular automatic recordings of the time series of the magnetic field, together with routine
manual absolute measurements for establishing dynamic baselines at Lampedusa Island …

The magnetic field satellite data are usually referred to geocentric coordinate reference
frame. Conversely, the magnetohydrodynamic waves modes in magnetized plasma depend …

Although initially it was presumed that foreshock waves would propagate directly into the
dayside magnetosphere, observational evidence for sinusoidal Pc3 waves in the …

The terrestrial foreshock as a region permeated by different types of plasma waves, various
particle populations, and strong wave activity is a subject of intensive investigations. Our …

A statistical study of Pc1–2 waves at southern polar latitudes is presented. Ultra-low
frequency geomagnetic field measurements collected at the Italian station Mario Zucchelli …

A long-duration upstream ultralow frequency (ULF) wave event was detected on 15
February 2009 by Cluster satellites, close to the bow shock nose. A clear wave activity was …
