A homogeneous stochastic model for earthquake occurrences
Anne S. Kiremidjian, Thalia Anagnos
1980, Open-File Report 80-1153
The objective of this study is to develop a probabilistic model for earthquake occurrences with temporal and spatial memory. Stochastic processes are used to characterize both the spatial and temporal dependencies of seismic occurrences along a fault. Currently, only homogeneous space and time transitions are considered. The resulting process however...

1980, Open-File Report 80-205
Three exploratory wells were drilled for geological, geophysical, and hydrological purposes in Salt Valley, Grand County, Utah. Cap rock, salt, and interbeds of the Paradox Member of the Hermosa Formation of Middle Pennsylvanian age were penetrated. The observed depth below land surface of the cap rock-salt interface ranges from 163...

1980, Open-File Report 80-591
A coal deposit in Bay County, Mich., typical of Pennsylvanian-coal deposits in the State, was studied to determine the degree to which hydrologic factors might affect future coal mining. The coal deposit, which averages about 0.5 meters in thickness, lies 50 meters below land surface. It is part of a...

Grinnell and Sperry Glaciers, Glacier National Park, Montana: A record of vanishing ice
Arthur Johnson
1980, Professional Paper 1180
Grinnell and Sperry Glaciers, in Glacier National Park, Mont., have both shrunk considerably since their discovery in 1887 and 1895, respectively. This shrinkage, a reflection of climatic conditions, is evident when photographs taken at the time of discovery are compared with later photographs. Annual precipitation and terminus-recession measurements, together with...
