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 ...
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 ...
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 ...
Do trench sediments affect great earthquake occurrence in subduction zones?
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1989-03)
Seismic energy release is dominated by the underthrusting earthquakes in subduction zones, and this energy release is further concentrated in a few subduction zones. While some subduction zones are characterized by the ...
The core shadow zone boundary and lateral variations of the P velocity structure of the lowermost mantle
(Elsevier, 1989-04-01)
The recent determination of high-quality, short-period P-wave amplitude profiles near the core shadow zone for three source-receiver combinations allows an exploration of lateral variations in P velocity structure at the ...
Source process of the great 1971 Solomon Islands doublet
(Elsevier, 1989-09)
Large underthrusting earthquakes in the Solomon Islands tend to occur as multiplets, separated by a few hours to several days in time and 30-100 km in space. The largest sequence, a doublet on July 14, 1971 (Mw = 8.0) and ...
Introduction to subduction zones
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1988-09)
Observations of teleseismic P wave coda for underground explosions
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1988-03)
The early P wave coda (5–15 sec after the first arrival) of underground explosions at the Nevada Test Site is studied in the time domain using 2082 teleseismic short-period recordings, with the intent of identifying ...
