Chlorite control of correlations between strain and anisotropy of magnetic susceptibility
(Elsevier, 1990)
Anisotropy of magnetic susceptibility (AMS) has in the past been used as an indicator of finite strain; mathematical relationships between the measured AMS ellipsoid and the finite strain ellipsoid in slates are numerous. ...
Linear and nonlinear computations of the 1992 Nicaragua earthquake tsunami
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Numerical computations of tsunamis are made for the 1992 Nicaragua earthquake using different governing equations, bottom frictional values and bathymetry data. The results are compared with each other as well as with the ...
A theory of ionospheric thermal radiation
(Elsevier, 1966-08)
The ionosphere is considered as a dissipative medium in which the random thermal motions of the charged particles act as a source of thermal radiation. Attention has been focused on the electrons colliding with ions and ...
Modelling of composition changes during F-region storms: a reassessment
(Elsevier, 1991)
A recalculation of the global changes of thermospheric gas composition, resulting from strong heat inputs in the auroral ovals, shows that (contrary to some previous suggestions) widespread increases of mean molecular mass ...
Measurements of the dynamics and coupling of the equatorial thermosphere and the F-region ionosphere in Peru
(Elsevier, 1988)
Simultaneous Fabry-Perot Interferometer (FPI) and Incoherent Scatter Radar (ISR) observations from Arequipa and Jicamarca, Peru, respectively, were obtained on 24 and 25 September 1986, during which there was substantial ...
Fluorescence as a source of noise in Q-switched ruby laser atmospheric backscattering experiments
(Elsevier, 1969-06)
Interpretation of the results of atmospheric baekscattering experiments, when using a Q-switched ruby laser as the source of photons, requires consideration of several sources of noise in the statistical analysis. This ...
Response of the neutral particle upper atmosphere to the solar eclipse of 7 March 1970
(Elsevier, 1972-04)
A series of five pitot probes were launched from Wallops Island, Va. (38[deg]N) in conjunction with the solar eclipse, 7 March 1970. Three soundings were programmed to occur at 40, 80 and 100 per cent obscuration of the ...
Separation of paramagnetic and ferrimagnetic susceptibilities using low temperature magnetic susceptibilities and comparison with high field methods
(Elsevier, 1994-02)
Magnetic susceptibility of rocks can be dominated by diamagnetic and paramagnetic matrix minerals, ferrimagnetic and antiferromagnetic trace minerals, or a combination. The interpretation of magnetic fabric data (anisotropy ...
Asperity distribution and earthquake occurrence in the southern Kurile Islands arc
(Elsevier, 1987-11)
The seismicity in the southern Kurile Islands arc is characterized by a complex overlapping of aftershock zones of a few great and many large earthquakes (Ms [greater, double equals] 7.0). The spatial relationships of these ...
Validation of HRDI MLT winds with meteor radars
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
A validation study of the mesospheric and lower-thermospheric (MLT) wind velocities measured by the High-Resolution Doppler Imager (HRDI) on board the Upper-Atmosphere Research Satellite (UARS) has been carried out, comparing ...
