Foreshock Ion Motion Across Discontinuities: Formation of Foreshock Transients
Journal of Geophysical Research: Space Physics, 2023AbstractIn the ion foreshock, hot flow anomalies (HFAs) and foreshock bubbles (FBs) are two types of foreshock transients that have the strongest fluctuations, which can disturb the magnetosphere‐ionosphere system and increase shock acceleration efficiency.

Foreshock cavities and internal foreshock boundaries
Planetary and Space Science, 2011Abstract We present two case studies of cluster encounters with foreshock cavities. For one event, we are able, for the first time, to accurately relate the observation of a foreshock cavity to the measured position of the bow shock. This allows us to compute the shock angle, a vital parameter in models of foreshock cavity formation, with greater ...

This chapter revisits ‘the Cornish commotion’ of 1548 — a short-lived but, from the Crown's point of view, deeply troubling émeute which flared up in West Cornwall in April that year, during the course of which a royal commissioner who was overseeing the removal of images from local churches was killed.

IN February 1975, the Chinese Seismological Bureau successfully predicted a magnitude 7.3 earthquake near Haicheng, Liaoning Province. From their reports, it is obvious that many methods such as radon count, abnormal animal behaviour, seismic velocity, and tilt and telluric current anomalies were considered in making the long term prediction1.

Statistical model of earthquake foreshocks
Physical Review A, 1992We propose a statistical model of rupture as a mechanism for the occasionally observed marked increase of seismic activity prior to a great earthquake. The physical ingredients of the model are those of geometrical inhomogeneity and viscoelastic creep.

Correlation of Foreshocks and Aftershocks and Asperities
pure and applied geophysics, 1984A close correlation in spatial distribution of local seismic activity and energy release patterns before and after the 1979 Petatlan, Mexico earthquake suggests heterogeneity within the fault plane of this major low-angle thrust event associated with subduction along the Middle America Trench.

An overview of the observations of backstreaming electrons in the foreshock and the mechanisms that have been proposed to explain their properties will be presented. A primary characteristic of observed foreshock electrons is that their velocity distributions are spatially structured in a systematic way depending on distance from the magnetic field ...

Foreshocks and earthquake prediction
Tectonophysics, 1972Abstract If a group of foreshocks can be distinguished from ordinary seismic activities, it would contribute to earthquake prediction. In the case of two Japanese earthquakes, which were preceded by immediate foreshocks, the coefficient “b” in the magnitude versus frequency equation was significantly smaller than that of the aftershocks or of the ...
