Eastern Approaches: Interball in the International Solar‐Terrestrial Program
Perspectives of Earth and Space Scientists, 2022 Progress in space plasma physics, or Heliophysics, necessarily requires the combined efforts of scientists in many nations employing observations from many spacecraft and ground‐based observatories.

Local bow shock environment during magnetosheath jet formation: results from a hybrid-Vlasov simulation [PDF]
Annales Geophysicae, 2023 Magnetosheath jets are plasma structures that are characterised by enhanced dynamic pressure and/or plasma velocity. In this study, we investigate the formation of magnetosheath jets in four two-dimensional simulation runs of the global magnetospheric ...

Journal of Geophysical Research: Solid EarthAbstractForeshocks are spatially clustered seismic events preceding large earthquakes. Since the dawn of seismology, their occurrence has been identified as a possible mechanism leading to further crustal destabilization, hence, to major failures. However, several cases occurred without any previous anomalous seismic activity, so that the hypothesis of

Nature Communications, 2021 Studies of Mercury’s foreshock have analyzed in detail the properties of ultra-low frequency waves. However, an open question remains in regards to understanding favorable conditions for these planetary foreshocks waves. Here, we report that 0.05–0.41 Hz

GéosciencesThe advanced determination of the type (foreshock–aftershock–swarm) of an ongoing seismic cluster is quite challenging; only retrospective solutions have thus far been proposed.

Comparing foreshock characteristics and foreshock forecasting in observed and simulated earthquake catalogs [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractIn this paper, we compare the empirical results regarding foreshocks obtained from the Japan data with results for synthetic catalogs in order to clarify whether or not the corresponding results are consistent with the description of the seismicity by a superposition of background activity and epidemic‐type aftershock sequence (ETAS) models ...

Oblique propagation and temperature effects on the resonant right-hand ion beam instability
Frontiers in Astronomy and Space Sciences, 2023 The resonant right-hand instability (RHI) is often the dominant mode driven by reflected ions upstream of Earth’s quasi-parallel bow shock. In the tradition of Peter Gary, this paper further explores the right-hand instability using numerical solutions ...

Geophysical Research LettersWe investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station.

Substorm Effects on Chorus Emissions Modulated by ULF Waves
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.
