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 ...
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 ...
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 ...
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 ...
Earthquake source processes and subduction regime in the Santa Cruz Islands region
(Elsevier, 1990)
The source process of two large earthquakes that occurred in the Santa Cruz Islands subduction zone has been studied, one with a surface wave magnitude MS = 7.9 in 1966 and the other with MS = 7.7 in 1980. The seismic ...
An intercomparison between the GSWM, UARS, and ground based radar observations: a case-study in January 1993
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
The Global-Scale Wave Model (GSWM) is a steady-state two-dimensional linearized model capable of simulating the solar tides and planetary waves. In an effort to understand the capabilities and limitations of the GSWM ...
Modeling the seismic source and tsunami generation of the December 12, 1992 Flores Island, Indonesia, earthquake
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
On December 12, 1992 a large earthquake ( M s 7.5) occurred just north of Flores Island, Indonesia which, along with the tsunami it generated, killed more than 2,000 people. In this study, teleseismic P and SH waves, as ...
Two 1993 Kamchatka earthquakes
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Two earthquakes occurred in 1993 off southern Kamchatka. They have similar surface wave magnitudes, focal mechanisms, and depths, but have distinctly different characteristics. The November earthquake is a standard or ...
On the dynamics and composition of the high-latitude thermosphere
(Elsevier, 1991-09)
Recent experimental measurements of the dynamics of the neutral upper thermosphere have demonstrated the important roles of ion-drag and Joule heating processes in establishing the basic neutral wind morphology and controlling ...
