Caribbean Plate Boundary Kinematics
Research Guide
What is Caribbean Plate Boundary Kinematics?
Caribbean Plate Boundary Kinematics studies relative motions between the Caribbean, Nazca, and South American plates using earthquake slip vectors and GPS velocities to model oblique convergence and escape tectonics.
Research integrates focal mechanisms, seismicity patterns, and geodetic data to quantify plate velocities. Key works include Molnár and Sykes (1969) with 827 citations analyzing tectonics via seismic data, and Trenkamp et al. (2002) with 475 citations from CASA GPS observations. Over 10 foundational papers exceed 300 citations each.
Why It Matters
Kinematic models predict seismicity along plate boundaries, informing hazard mitigation in the Caribbean and northern South America. DeMets (2001, 392 citations) provides Cocos-Caribbean motion estimates critical for Central American Volcanic Arc slip. Trenkamp et al. (2002, 475 citations) reveal wide plate margin deformation via GPS, guiding earthquake risk assessment in southern Central America. Pindell and Kennan (2009, 773 citations) update tectonic evolution for resource exploration in the Gulf of Mexico.
Key Research Challenges
Resolving Oblique Convergence Rates
Quantifying slip partitioning between strike-slip and convergence remains difficult due to sparse GPS data. DeMets (2001) estimates Cocos-Caribbean motion but highlights uncertainties in volcanic arc slip. Trenkamp et al. (2002) observe wide deformation complicating rigid plate assumptions.
Integrating Long-Term vs. Present Motions
Reconciling geological records with modern GPS velocities challenges evolutionary models. Sykes et al. (1982, 333 citations) calibrate Caribbean motion over 7 million years using seismic zones. Pindell et al. (1988, 381 citations) propose plate-kinematic frameworks needing GPS validation.
Modeling Escape Tectonics Blocks
Escape tectonics in northern South America requires multi-plate interactions beyond binary models. Pindell and Kennan (2009) synthesize Gulf of Mexico-Caribbean evolution but note mantle frame discrepancies. DeMets et al. (2000, 353 citations) constrain Caribbean-North America motion via GPS yet underexplore South American interactions.
