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 ...
The calculated and observed ionospheric properties during Atmospheric Explorer-C satellite crossings over Millstone Hill
(Elsevier, 1978-01)
The Atmospheric Explorer-C (AE-C) satellite passed almost directly over the Millstone Hill incoherent scatter radar station on 14 February 1974 and passed within the near vicinity of the station on 15 February 1974. ...
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 1957 great Aleutian earthquake
(Birkhäuser-Verlag; Springer Science+Business Media, 1994-03)
The 9 March 1957 Aleutian earthquake has been estimated as the third largest earthquake this century and has the longest aftershock zone of any earthquake ever recorded—1200 km. However, due to a lack of high-quality seismic ...
Characteristics of ionospheric thermal radiation
(Elsevier, 1966-08)
A theoretical observation of the characteristics of ionospheric thermal radiation is made using a linear theory, based on a macroscopic concept with the aid of fluctuating electromagnetic field theory. The thermal noise ...
Rupture process of large earthquakes in the northern Mexico subduction zone
(Birkhäuser-Verlag; Springer Science+Business Media, 1994-03)
The Cocos plate subducts beneath North America at the Mexico trench. The northernmost segment of this trench, between the Orozco and Rivera fracture zones, has ruptured in a sequence of five large earthquakes from 1973 to ...
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 ...
Inference of ground surface temperature history from subsurface temperature data: Interpreting ensembles of borehole logs
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1996-08)
Ground surface temperature histories (GSTHs) inferred from borehole temperaturedepth ( T-z ) data are often degraded, to a various extent, by random or systematic noise in the T-z data and in the measurements of thermophysical ...
Introduction to “tsunamis: 1992–94”
