Episodic strain accumulation in Southern California
W. Thatcher
1976, Science (194) 691-695
Reexamination of horizontal geodetic data in the region of recently discovered aseismic uplift has demonstrated that equally unusual horizontal crustal deformation accompanied the development of the uplift. During this time interval compressive strains were oriented roughly normal to the San Andreas fault, suggesting that the uplift produced little shear strain...

A. J. Boettcher, R. M. Haralick, C. A. Paul, Norman Smothers
1976, Journal of Research of the U.S. Geological Survey (4) 727-732
Thermal-infrared imagery was used to locate ground-water inflow along a 50-mile (80-kilometre) reach of the Kootenai River and Lake Koocanusa and a 55-mi (88-km) reach of the Clark Fork of the Columbia River in northwestern Montana and northeastern Idaho. The imagery confirmed that measured streamflow gains below Noxon Rapids Dam,...

Este F. Hollyday
1976, Journal of Research of the U.S. Geological Survey (4) 517-531
Imagery from the first Earth Resources Technology Satellite (renamed Landsat-1) was used to discriminate physical features of drainage basins in an effort to improve equations used to estimate streamflow characteristics at gaged and ungaged sites. Records of 20 gaged basins in the Delmarva Peninsula of Maryland, Delaware, and Virginia were...

Relocation of local earthquakes by seismic ray tracing
E.R. Engdahl, W.H.K. Lee
1976, Journal of Geophysical Research (81) 4400-4406
Seismic ray tracing is used to relocate a set of local earthquakes recorded by a dense seismic array in Bear Valley, California. The crustal velocity structure is two-dimensional and incorporates most of the known and inferred velocity differences in the region. Relocated hypocenters fall within the San Andreas fault zone,...

Mathematical models for nonparametric inferences from line transect data
K.P. Burnham, David R. Anderson
1976, Biometrics (32) 325-336
A general mathematical theory of line transects is develoepd which supplies a framework for nonparametric density estimation based on either right angle or sighting distances. The probability of observing a point given its right angle distance (y) from the line is generalized to an arbitrary function g(y). Given only that...
