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 ...

Impact of Foreshock Transients on the Flank Magnetopause and Magnetosphere and the Ionosphere
Frontiers in Astronomy and Space Sciences, 2021 Mesoscale (on the scales of a few minutes and a few RE) magnetosheath and magnetopause perturbations driven by foreshock transients have been observed in the flank magnetotail.

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 ...

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.

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

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 ...

Recognizing the waveform of a foreshock [PDF]
, 2020 Abstract The 2011 Mw9.1 Tohoku, Japan, earthquake is the paradigmatic example of an earthquake anticipated by a significant foreshock activity, with a Mw7.3 earthquake occurred two days before, within about 10 km 1. Recent results 2 show that statistically relevant changes can be found in the magnitude distribution after the Mw7.3 foreshock but

On the statistical significance of foreshock sequences in Southern California [PDF]
, 2020 Earthquake foreshocks may provide information that is critical to short-term earthquake forecasting. However, foreshocks are far from ubiquitously observed, which makes the interpretation of ongoing seismic sequences problematic.

Unusual Martian Foreshock Waves Triggered by a Solar Wind Stream Interaction Region
The Astrophysical Journal Letters, 2023 Planetary bow shocks noncollisionally dissipate the incident bulk flow energy of solar wind into some other forms. To what extent and how solar wind disturbances affect the energy dissipation processes at the bow shocks on different planets remain ...
