Block models of crustal motion in southern California constrained by GPS measurements
[1] We estimate slip rates on major active faults in southern California using a block model constrained by Global Positioning System measurements of interseismic deformation. The block modelExpand
A geological and geophysical context for the Wenchuan earthquake of 12 May 2008, Sichuan, People's Republic of China
On 12 May 2008, a magnitude 7.9 earthquake ruptured the Longmen Shan margin of the eastern Tibetan plateau. This event occurred within the context of long-term uplift and eastward enlargement of theExpand
Subducted slabs and the geoid: Constraints on mantle rheology and flow
Geoid anomalies are primarily the result of the density contrasts driving mantle convection and plate motion. The total geoid anomaly resulting from a given density contrast in a convecting earth isExpand
Effects of plate bending and fault strength at subduction zones on plate dynamics
For subduction to occur, plates must bend and slide past overriding plates along fault zones. Because the lithosphere is strong, significant energy is required for this deformation to occur, energyExpand
Estimates of Seismic Potential in the Marmara Sea Region from Block Models of Secular Deformation Constrained by Global Positioning System Measurements
We model the geodetically observed secular velocity field in north- western Turkey with a block model that accounts for recoverable elastic-strain ac- cumulation. The block model allows us toExpand
Localization of gravity and topography: constraints on the tectonics and mantle dynamics of Venus
SUMMARY We develop a method for spatio-spectral localization of harmonic data on a sphere and use it to interpret recent high-resolution global estimates of the gravity and topography of Venus in theExpand
Relatively recent construction of the Tien Shan inferred from GPS measurements of present-day crustal deformation rates
THE Tien Shan—a high, seismically active intracontinental mountain belt, 1,000–2,000 km north of the Himalaya—has grown as a result of India's collision with Asia1. The crustal shortening (˜ 200 ± 50Expand
Long-wavelength variations in Earth’s geoid: physical models and dynamical implications
The seismic velocity anomalies resolved by seismic tomography are associated with variations in density that lead to convective flow and to dynamically maintained topography at the Earth’s surface,Expand
Thermal and Magmatic Evolution of the Moon
As with all science, our continually developing concepts of lunar evolution are firmly tied to both new types of observations and the integration of these observations to the known pool of data. ThisExpand
Present day kinematics of the Eastern California Shear Zone from a geodetically constrained block model
We use Global Positioning System (GPS) data from 1993–2000 to determine horizontal velocities of 65 stations in eastern California and western Nevada between 35° and 37° N. We relate the geodeticExpand
