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

Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

Magnetic Signatures of a Plasma Wake Behind the Swarm Satellites
Abstract This study provides first observational evidence of a plasma wake behind ESA's Swarm satellites, manifesting itself by a brief magnetic field strength spike and bipolar field variations in transverse direction. These magnetic signatures occur only near the dip‐equator where the magnetic declination is close to zero.

Abstract The oceanic tidal magnetic field, mainly driven by the circular orbital motion of the Moon, is an essential part of the time‐varying geomagnetic field. The previously adopted time‐harmonic (TH) base worked well in fitting the primary M2 ${M}_{2}$ tidal field, but extracting the other weaker modes like the N2 ${N}_{2}$ was difficult with only a

Abstract Poleward boundary intensifications (PBIs) are one of the most common auroral disturbances and have been shown to play a key role in substorm dynamics. PBIs are commonly interpreted as the ionospheric signature of magnetotail reconnection, providing insight into X‐line evolution.
