An assessment of the relative importance of body and plasma properties in determining the ion current distribution in the wake of an ionospheric satellite
(Elsevier, 1980-06)
Measurements of ion currents (I+), electron temperatures (Te), values of satellite potential ([phi]s), ion concentrations (N+), and composition (M+), from the cylindrical electrostatic probe and the Bennett ion mass ...
Plasma dynamics in the night-time F-region at Arecibo
(Elsevier, 1985)
Incoherent scatter radar observations of the night-time F-layer at Arecibo, Puerto Rico, are used to determine horizontal gradients in peak electron density and the F-layer height. At certain times of night, in both the ...
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 ...
Large earthquakes in the macquarie ridge complex: Transitional tectonics and subduction initiation
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1989-03)
While most aspects of subduction have been extensively studied, the process of subduction initiation lacks an observational foundation. The Macquarie Ridge complex (MRC) forms the Pacific-Australia plate boundary between ...
The angular distribution of ion flux around an ionospheric satellite
(Elsevier, 1973-03)
Ion measurements from the Explorer 31 satellite were used to determine the angular distribution of ions around the satellite. The ion distributions were compared with the electron distributions measured on the same satellite. ...
Large intermediate-depth earthquakes and the subduction process
(Elsevier, 1988-12)
This study provides an overview of intermediate-depth earthquake phenomena, placing emphasis on the larger, tectonically significant events, and exploring the relation of intermediate-depth earthquakes to shallower seismicity. ...
A note on multiple flow equilibria
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1989-12)
A set of ordinary differential equations describing a mechanical system subject to forcing and dissipation is considered. A topological argument is employed to show that if all time-dependent solutions of the governing ...
Non-adiabatic motion of charged particles traversing a weak magnetic field: Pitch angle scattering
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1964-12)
A charged particle moves with velocity v in a constant non-uniform magnetic field H , spiralling with Larmor radius R . If R is small compared with the scale length L of the field, the magnetic moment associated with the ...
Effect of longitudinal electrostatic field on the whistler mode propagation in a warm magneto-ionic medium
(Elsevier, 1968-02)
The dispersion equation for a whistler mode propagation in a warm plasma, subjected to parallel static electric and magnetic fields, is derived by using a linearized coupled Vlasov-Maxwell equation. From the derived ...
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 ...
