Observations of a new foreshock region upstream of a foreshock bubble's shock [PDF]
Geophysical Research Letters, 2016 Earth's foreshock is a region within the solar wind upstream of Earth's bow shock filled with backstreaming solar wind particles reflected at the shock.

Traveling Foreshocks and Transient Foreshock Phenomena [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractWe use the multispacecraft capabilities of the Cluster and Time History of Events and Macroscale Interactions during Substorms (THEMIS) missions to show that two types of foreshock may be detected in spacecraft data. One is the global foreshock that appears upstream of the Earth's quasi‐parallel bow shock under steady or variable interplanetary

Helium in the Earth's foreshock: a global Vlasiator survey [PDF]
Annales Geophysicae, 2020 The foreshock is a region of space upstream of the Earth's bow shock extending along the interplanetary magnetic field (IMF). It is permeated by shock-reflected ions and electrons, low-frequency waves, and various plasma transients.

On the edge of the foreshock: model-data comparisons [PDF]
Annales Geophysicae, 2008 We present the results of a global hybrid code simulation for the solar wind-interaction with the Earth's magnetosphere during an interval of steady radial IMF.

Pervasive Foreshock Activity Across Southern California [PDF]
Geophysical Research Letters, 2019 Foreshocks have been documented as preceding less than half of all mainshock earthquakes. These observations are difficult to reconcile with laboratory earthquake experiments and theoretical models of earthquake nucleation, which both suggest that ...

Irregular rupture process of the 2022 Taitung, Taiwan, earthquake sequence [PDF]
Scientific Reports, 2023 In September 2022, two destructive earthquakes of moment magnitude (M w) 6.6 (foreshock) and 7.1 (mainshock) occurred in Taitung County, south-eastern Taiwan.

Statistical study of foreshock cavitons [PDF]
Annales Geophysicae, 2013 In this work we perform a statistical analysis of 92 foreshock cavitons observed with the Cluster spacecraft 1 during the period 2001–2006. We analyze time intervals during which the spacecraft was located in the Earth's foreshock with durations ...

The statistics of foreshock cavities: results of a Cluster survey [PDF]
Annales Geophysicae, 2008 We use Cluster magnetic field, thermal ion, and energetic particle observations upstream of the Earth's bow shock to investigate the occurrence patterns of foreshock cavities. Such cavities are thought to form when bundles of magnetic field connect to

New Physical Implications From Revisiting Foreshock Activity in Southern California
Geophysical Research Letters, 2023 Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...

ARTEMIS Observations of Foreshock Transients in the Midtail Foreshock
Geophysical Research Letters, 2020 AbstractForeshock transients such as hot flow anomalies (HFAs) are frequently observed in the dayside foreshock. They can disturb the local bow shock, magnetopause, and consequently the magnetosphere‐ionosphere system through dynamic pressure perturbations. Recent multipoint observations found that such perturbations can even propagate from the dayside
