Foreshocks and earthquake prediction

Tectonophysics, 1975
Abstract Results of a statistical investigation of the magnitude and time distributions of foreshocks in the area of Greece are reported. Further evidence is presented that the parameter b , in the frequency—magnitude relation, has a smaller value before than after the main shock, and that the time distribution of foreshocks follows a statistical ...

Foreshock compressional boundary

Journal of Geophysical Research: Space Physics, 2009
We employ 2.5‐D electromagnetic, hybrid simulations that treat ions kinetically via particle‐in‐cell methods and electrons as a massless fluid to study the formation and properties of a newly discovered boundary named the foreshock compressional boundary (FCB).

Solar wind deceleration in the foreshock as the source of the foreshock compressive structures

The foreshock is a turbulent region located upstream of the quasi parallel bow shock. It is dominated by waves and reflected back-streaming particles that interact with each other and result in the creation of different foreshock phenomena. Xirogiannopoulou et al.

Foreshock Transients and Their Geoeffects

2020
<p>Foreshock transients are frequently observed upstream from the bow shock (such as Hot Flow Anomalies, foreshock cavities, and foreshock bubbles). They play a significant role in the mass, energy and momentum transport from the solar wind into the magnetosphere and impact the whole&#160 ...

Formation of cavities in the foreshock

AIP Conference Proceedings, 2007
Results from electromagnetic hybrid simulations (kinetic ions, fluid electrons) of the magnetosphere during radial IMF are discussed with focus on the structure of the ion foreshock and the associated ULF waves. In particular, we show that this region is populated with numerous structures that are associated with large (∼50%) drops in solar wind ...
