THE EFFECT OF SUBIONOSPHERIC PROPAGATION ON WHISTLERS RECORDED BY THE DEMETER SATELLITE – OBSERVATION AND MODELLING

The effect of subionospheric propagation on whistlers recorded by the DEMETER satellite – observation and modelling

During a routine analysis of whistlers on the wide-band VLF recording of the DEMETER satellite, a specific signal structure of numerous fractional-hop whistlers, termed the "Spiky Whistler" (SpW) was identified.These signals appear to be composed of a conventional whistler combined by the compound mode-patterns of guided wave propagation, suggestin

Faults Get Colder Through Transient Granular Vortices

Abstract Fault temperatures govern their weakening and control the dynamics of earthquakes during slip.Despite predictions of significant temperature rise within fault gouges during earthquake events, observations of frictional melting zones along exhumed faults are relatively rare.Could there be a heat transfer mechanism, previously not considered
