Geophysical research utilizes analytical and numerical tools to quantify tectonic processes. Basic geophysical research lays the ground for understanding of Earth processes, which affect natural hazards and resource estimation.
Mid-plate volcanoes load tectonic plates and cause the plates to flex. Plate flexure, in turn, can modify the volcanic eruptions. In transform plate boundaries, the majority of relative plate motion takes place by lateral displacement between two tectonic plates. Read ten Brink and others research papers.

At rift zones the continental crust and lithosphere are subjected to extensional stresses, which result in the formation of sedimentary basins. These basins sometime accumulate natural resources of oil, gas and water. Read ten Brink and others research papers.

In subduction plate boundaries, one tectonic plate sinks under another tectonic plate. The process of sinking is often accompanied by large earthquakes, volcanism, and the building of mountains. Read ten Brink and others research papers.

Shallower structure and geomorphology of the southern Puerto Rico offshore margin
Bathymetric Terrain Model of the Puerto Rico Trench and the Northeastern Caribbean Region for Marine Geological Investigations
Multibeam bathymetry data collected in the Puerto Rico Trench and Northeast Caribbean region are compiled into a seamless bathymetric terrain model for broad-scale geological investigations of the trench system. These data, collected during eight separate surveys between 2002 and 2013, covering almost 180,000 square kilometers are published here in large format map sheet and digital spatial data.
Slab tears and intermediate-depth seismicity
Active tectonic regions where plate boundaries transition from subduction to strike slip can take several forms, such as triple junctions, acute, and obtuse corners. Well-documented slab tears that are associated with high rates of intermediate-depth seismicity are considered here: Gibraltar arc, the southern and northern ends of the Lesser Antilles arc, and the northern end of Tonga trench. Seism
Seismic evidence for a slab tear at the Puerto Rico Trench
The fore-arc region of the northeast Caribbean plate north of Puerto Rico and the Virgin Islands has been the site of numerous seismic swarms since at least 1976. A 6 month deployment of five ocean bottom seismographs recorded two such tightly clustered swarms, along with additional events. Joint analyses of the ocean bottom seismographs and land-based seismic data reveal that the swarms are locat

Gravity modeling of the Muertos Trough and tectonic implications (north-eastern Caribbean)
The Muertos Trough in the northeast Caribbean has been interpreted as a subduction zone from seismicity, leading to infer a possible reversal subduction polarity. However, the distribution of the seismicity is very diffuse and makes definition of the plate geometry difficult. In addition, the compressive deformational features observed in the upper crust and sandbox kinematic modeling do not neces
Extension in Mona Passage, Northeast Caribbean
As shown by the recent Mw 7.0 Haiti earthquake, intra-arc deformation, which accompanies the subduction process, can present seismic and tsunami hazards to nearby islands. Spatially-limited diffuse tectonic deformation within the Northeast Caribbean Plate Boundary Zone likely led to the development of the submerged Mona Passage between Puerto Rico and the Dominican Republic. GPS geodetic data and
Morphotectonics of the central Muertos thrust belt and Muertos Trough (northeastern Caribbean)
Multibeam bathymetry data acquired during the 2005 Spanish R/V Hesp??rides cruise and reprocessed multichannel seismic profiles provide the basis for the analysis of the morphology and deformation in the central Muertos Trough and Muertos thrust belt. The Muertos Trough is an elongated basin developed where the Venezuelan Basin crust is thrusted under the Muertos fold-and-thrust belt. Structural v
Bivergent thrust wedges surrounding oceanic island arcs: Insight from observations and sandbox models of the northeastern caribbean plate
At several localities around the world, thrust belts have developed on both sides of oceanic island arcs (e.g., Java-Timor, Panama, Vanuatu, and the northeastern Caribbean). In these localities, the overall vergence of the backarc thrust belt is opposite to that of the forearc thrust belt. For example, in the northeastern Caribbean, a north-verging accretionary prism lies to the north of the Easte
