Compositional variations on the Moon: Recalibration of Galileo solid‐state imaging data for the Orientale region and farside Compositional variations on the Moon: Recalibration of Galileo solid‐state imaging data for the Orientale region and farside
Updated radiometric calibration and systematic processing procedures for Galileo solid‐state imaging (SSI) data from the first (1990) Earth‐Moon encounter are presented. These procedures were applied to a whole‐disk imaging sequence of the Moon centered near Mare Orientale, called Lunmap 14 (L14). Processing of L14 data included radiometric calibration, subpixel coregistration, scattered...

Comparison of BASS and VACM current measurements during STRESS Comparison of BASS and VACM current measurements during STRESS
Current measurements from a vector-averaging current meter (VACM) on a subsurface mooring and a benthic acoustic stress sensor (BASS) on a bottom tripod are compared to assess their relative accuracy. The instruments were deployed off northern California at a midshelf site (water depth approximately 90 m) as part of the STRESS (Sediment Transport Events on Shelves and Slopes) field...

Strain accumulation across the central Nevada seismic zone, 1973–1994 Strain accumulation across the central Nevada seismic zone, 1973–1994
Five trilateration networks extending for 280 km along the central Nevada seismic zone (1915 Pleasant Valley, M = 7.3; 1954 Dixie Valley, M = 6.8; 1954 Stillwater, M = 6.8; 1954 Rainbow Mountain, M = 6.6; 1954 Fairview Peak, M = 7.1; and 1932 Cedar Mountain, M = 7.2) have been surveyed 6 times since 1973 to determine deformation along the zone. Within the precision of measurement the...

Changes in long‐term extension rates associated with the Morgan Hill and Loma Prieta earthquakes in California Changes in long‐term extension rates associated with the Morgan Hill and Loma Prieta earthquakes in California
Frequent measurements since mid‐1981 of the distances from a geodetic monument located about 100 km south‐southeast of San Francisco to three monuments 30 to 40 km distant provide an unusually complete record of the deformation before and after two nearby earthquakes, the 1984 Morgan Hill (ML = 6.2) and 1989 Loma Prieta (Ms = 7.1) earthquakes. Except possibly for the first few months...

Strain accumulation in Owens Valley, California, 1974 to 1988 Strain accumulation in Owens Valley, California, 1974 to 1988
Strain accumulation observed over the 1974 to 1988 interval in a 25 by 100 km aperture trilateration network spanning Owens Valley is adequately described by a strain rate that is uniform in space and time. The tensor strain-rate components referred to a coordinate system with the 2 axis directed N18°W (parallel to the trend of the valley) and the 1 axis N72°E are ∈˙11′ = 0.042 ± 0.014...

Geodetic monitoring of the southern San Andreas Fault, California, 1980-1991 Geodetic monitoring of the southern San Andreas Fault, California, 1980-1991
Five geodetic arrays (10 to 40 km aperture) located along the San Andreas fault have been surveyed frequently (several times in most years) over the 1980–1991 interval to detect possible fluctuations in the deformation rate. In each survey of an array the distances between the same four to seven pairs of geodetic monuments were measured. The distances measured (with corresponding...

Interseismic uplift at the Nankai subduction zone, southwest Japan, 1951–1990 Interseismic uplift at the Nankai subduction zone, southwest Japan, 1951–1990
Uplift as a function of time from 1951 through 1990 has been deduced from annual mean sea level measured at 15 tide gages along the Nankai subduction zone, southwest Japan. The recurrence interval for rupture of the Nankai subduction zone is about 100 years, and the most recent rupture was in late 1946. Thus the 1951–1990 uplift record covers most of the first half of the earthquake...
