SEASAT geoid anomalies and the Macquarie Ridge complex
(Elsevier, 1985-03-30)
The seismically active Macquarie Ridge complex forms the Pacific-India plate boundary between New Zealand and the Pacific-Antarctic spreading center. The Late Cenozoic deformation of New Zealand and focal mechanisms of ...
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 ...
Chemistry of the thermosphere and ionosphere
(Elsevier, 1979)
The ionosphere offers an excellent laboratory for the study of atomic and molecular processes. Densities are low, permitting highly reactive species to accumulate in measurable quantities. Temporal and spatial scales are ...
The source rupture process of the Great Banda Sea earthquake of November 4, 1963
(Elsevier, 1987-04)
The Banda Sea earthquake of November 4, 1963 is one of the largest (Mw = 8.3) intraplate events. It involved oblique thrusting at an intermediate depth within the subducted lithosphere near the abrupt bend in the southeastern ...
Equatorial night-time F-region events: a survey of 6300 A airglow intensity maps at Arecibo
(Elsevier, 1981-08)
6300 A nightglow intensities have been mapped along an arc following the emission layer. The resulting time vs zenith angle airglow maps show significant structure which is classified into three main types: meridional ...
Rupture of a seismic gap in southeastern Alaska: the 1972 Sitka earthquake (Ms 7.6)
(Elsevier, 1989-04-15)
The Sitka, Alaska, earthquake of July 30, 1972 (Ms = 7.6) is one of the largest strike-slip events since 1963. This earthquake is thought to have ruptured the Pacific-North America plate boundary segment between the large ...
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 ...
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 ...
