Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 1979 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 1979
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Interim report on the St. Elias, Alaska earthquake of 28 February 1979 Interim report on the St. Elias, Alaska earthquake of 28 February 1979
On 28 February 1979 an earthquake with surface wave magnitude (Ms) of 7.7 (W. Person, personal communication, 1979) occurred beneath the Chugach and St. Elias mountains of southern Alaska (fig. 1). This is a region of complex tectonics resulting from northwestward convergence between the Pacific and North American plates. To the east, the northwest-trending Fairweather fault accommodates...

A large landslide on Mars A large landslide on Mars
A large landslide deposit on the south wall of Gangis Chasma contains at least 100 billion m3of material that moved 60 km across the trough floor at a speed of more than 100 km/hr. The deposit consists of slump blocks at the head, hummocky material farther out, and a vast apron of longitudinally ridged material extending to the toe. The landslide deposit resembles many terrestrial ones...

Estimating pore and cement volumes in thin section Estimating pore and cement volumes in thin section
Point count estimates of pore, grain and cement volumes from thin sections are inaccurate, often by more than 100 percent, even though they may be surprisingly precise (reproducibility + or - 3 percent). Errors are produced by: 1) inclusion of submicroscopic pore space within solid volume and 2) edge effects caused by grain curvature within a 30-micron thick thin section. Submicroscopic...
