Paleomagnetism of the Upper Silurian and Lower Devonian carbonates of New York State: evidence for secondary magnetizations residing in magnetite
(Elsevier, 1982-12)
Paleomagnetic directions for the Upper Silurian and Lower Devonian carbonates of the Helderberg escarpment (New York State) differ from expected Late Silurian and Early Devonian directions for cratonic North America. The ...
Temporal variation of large intraplate earthquakes in coupled subduction zones
(Elsevier, 1989-04-15)
The focal mechanisms of intraplate earthquakes within subducting lithosphere are frequently used to infer large-scale stress regimes induced by slab-pull, bending or unbending, and lateral segmentation and undulations of ...
Great earthquakes and subduction along the Peru trench
(Elsevier, 1989-11)
Subduction along the Peru trench, between 9 and 15[deg] S, involves both large interplate underthrusting earthquakes and intraplate normal-fault earthquakes. The four largest earthquakes along the Peru trench are, from ...
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 ...
