Subduction zone coupling and tectonic block rotations in the North Island, New Zealand
- L. Wallace, J. Beavan, R. Mccaffrey, D. Darby
- Geology
- 1 December 2004
[1] The GPS velocity field in the North Island of New Zealand is dominated by the long-term tectonic rotation of the eastern North Island and elastic strain from stress buildup on the subduction zone…
Plate-boundary deformation associated with the great Sumatra–Andaman earthquake

TLDR
Fault locking, block rotation and crustal deformation in the Pacific Northwest
- R. Mccaffrey, A. Qamar, P. Zwick
- Geology
- 1 June 2007
SUMMARY
We interpret Global Positioning System (GPS) measurements in the northwestern United States and adjacent parts of western Canada to describe relative motions of crustal blocks, locking on…
Block kinematics of the Pacific-North America plate boundary in the southwestern United States from inversion of GPS, seismological, and geologic data
- R. Mccaffrey
- Geology
- 1 July 2005
[1] The active deformation of the southwestern United States (30°–41°N) is represented by a finite number of rotating, elastic-plastic spherical caps. GPS-derived horizontal velocities, geologic…
Oblique plate convergence, slip vectors, and forearc deformation
- R. Mccaffrey
- Geology
- 10 June 1992
Slip vectors from thrust earthquakes at subduction zones where convergence is oblique to the trench often point between the directions of relative plate convergence and normal to the trench axis,…
Active tectonics of northwestern U.S. inferred from GPS‐derived surface velocities
- R. Mccaffrey, R. King, S. Payne, M. Lancaster
- Geology
- 1 February 2013
Surface velocities derived from GPS observations from 1993 to 2011 at several hundred sites across the deforming northwestern United States are used to further elucidate the region's active…
Balancing the plate motion budget in the South Island, New Zealand using GPS, geological and seismological data
- L. Wallace, J. Beavan, R. Mccaffrey, K. Berryman, P. Denys
- Geology
- 2007
SUMMARY The landmass of New Zealand exists as a consequence of transpressional collision between the Australian and Pacific plates, providing an excellent opportunity to quantify the kinematics of…
Global frequency of magnitude 9 earthquakes
- R. Mccaffrey
- Geology
- 1 March 2008
For decades seismologists have sought causal relationships between maximum earthquake sizes and other properties of subduction zones, with the underlying notion that some subduction zones may never…
Crustal motion in Indonesia from Global Positioning System measurements
- Y. Bock, L. Prawirodirdjo, É. Calais
- Geology
- 1 August 2003
Terrestrial Reference Frame 2000. We compute poles of rotation for the Australia, Eurasia, and Pacific plates based on our analysis of the global GPS data. We find that regional tectonics is…
GPS and seismological constraints on active tectonics and arc‐continent collision in Papua New Guinea: Implications for mechanics of microplate rotations in a plate boundary zone
- L. Wallace, C. Stevens, Jones Taugaloidi
- Geology
- 1 May 2004
[1] The island of New Guinea is located within the deforming zone between the Pacific and Australian plates that converge obliquely at ∼110 mm/yr. New Guinea has been fragmented into a complex array…
