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

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

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.

Pervasive Foreshock Activity Across Southern California
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 ...

Relationship Between the 2019 Ridgecrest, California, MW7.1 Earthquake and Its MW6.4 Foreshock Sequence [PDF]
EntropyThe 2019 Ridgecrest MW7.1 earthquake has received significant attention due to its complex fault activity. It is also noticeable for its MW6.4 foreshock sequence.

Dynamics of the Foreshock Compressional Boundary and Its Connection to Foreshock Cavities [PDF]
Journal of Geophysical Research: Space Physics, 2013 AbstractWe use several global hybrid (kinetic ions, fluid electrons) simulation runs for steady and time‐varying interplanetary magnetic field (IMF) conditions to examine the dynamics of the foreshock compressional boundary (FCB) and its connection to foreshock cavities.

Foreshock Migration Preceding the 2016 Mw 7.0 Kumamoto Earthquake, Japan
Geophysical Research Letters, 2016 We investigated the spatiotemporal evolution of an earthquake sequence following a series of large shallow intraplate earthquakes, including a Mw 6.2 foreshock and Mw 7.0 main shock, in the Kumamoto area of Kyushu, SW Japan.

Foreshocks Explained by Cascades of Triggered Seismicity [PDF]
Journal of Geophysical Research: Solid Earth, 2003 The observation of foreshocks preceding large earthquakes and the suggestion that foreshocks have specific properties that may be used to distinguish them from other earthquakes have raised the hope that large earthquakes may be predictable. Among proposed anomalous properties are the larger proportion than normal of large versus small foreshocks, the ...

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.
