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.

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 ...

Sensors, 2020 Significant seismicity anomalies preceded the 25 October 2018 mainshock (Mw = 6.8), NW Hellenic Arc: a transient intermediate‐term (~2 yrs) swarm and a short‐term (last 6 months) cluster with typical time‐size‐space foreshock patterns: activity increase,

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.

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.

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.

Advances in Space Research, 1995
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 ...

MMS observations of wave activity in the particle foreshock bubble foreshock region
2020<p>Foreshock bubbles (FBs) are kinetic transient phenomena formed due to the interaction between IMF discontinuities and backstreaming energetic ions in Earth&#8217;s foreshock region. FBs can be driven by both rotational discontinuities and tangential discontinuities and are typically observed under higher solar wind ...
