“…2000 years is surprising given that triggering events, including major earthquakes and hurricanes have affected the region in recorded history. Pilkey et al (1980) found that sand layer frequency increases with increasing tectonic activity, which is highlighted by the comparison between the 500 and 700 year turbidity current recurrence in the tectonically influenced Navidad Basin (Seiglie et al, 1976), and the 3000-6000 year turbidity current Fig. 17.…”

“…0.07–0.08 mm year −1 ) long‐term sedimentation rates for the WB and VIB, respectively, fall within the lower end of the range of sedimentation rates calculated for basins adjacent to carbonate platforms (e.g. Bornhold & Pilkey, ; Seiglie et al ., ). The low sedimentation rates are influenced by the lack of gravity flow deposits and may be a combination of: (1) the ability of the high basin walls to accommodate significant quantities of sediment, (2) limited off‐shelf transport and infrequent seismic or storm triggers, causing the basin to be starved of turbidity current and debris flow deposits, or (3) low rates of pelagic production and limited input of material transported by water masses entering through the Anegada Passage (Fig.…”

“…). Unlike other intra‐platform carbonate basins such as Exhuma Sound in the Bahamas (Crevello & Schlager, ) and Navidad and Hispaniola‐Caicos basins (Bennetts & Pilkey, ; Seiglie et al ., ; Ditty et al ., ), the VIB lacks well‐defined basin‐wide turbidites or debris sheets within the upper few metres of the sedimentary section. Instead, these sand‐rich layers are restricted to the eastern most section of the basin, where numerous channels from the north and south walls of the basin and from the Ginger Basin to the NE coalesce in a distinct base of slope fan (Fig.…”

“…Studies of deep-water basins adjacent to modern carbonate platforms show that they contain a complex pattern of either basin-wide or marginal debris flow and turbidite deposits intercalated with thin, discontinuous sand layers and pelagic muds (e.g. Bornhold & Pilkey, 1971;Seiglie et al, 1976;Ditty et al, 1977;Schlager & Chermak, 1979;Crevello & Schlager, 1980;Droxler & Schlager, 1985;Andresen et al, 2003;Jorry et al, 2008;Webster et al, 2012). The continuity, thickness, and composition of the sand and pelagic intervals within these basins have been used to determine the source area characteristics, transport-initiating trigger events, and how the basin morphology interacts with individual flows to affect their transport.…”

The Virgin Islands and Whiting basins in the Northeast Caribbean are deep, structurally controlled depocentres partially bound by shallow‐water carbonate platforms. Closed basins such as these are thought to document earthquake and hurricane events through the accumulation of event layers such as debris flow and turbidity current deposits and the internal deformation of deposited material. Event layers in the Virgin Islands and Whiting basins are predominantly thin and discontinuous, containing varying amounts of reef‐ and slope‐derived material. Three turbidites/sandy intervals in the upper 2 m of sediment in the eastern Virgin Islands Basin were deposited between ca. 2000 and 13 600 years ago, but do not extend across the basin. In the central and western Virgin Islands Basin, a structureless clay‐rich interval is interpreted to be a unifite. Within the Whiting Basin, several discontinuous turbidites and other sand‐rich intervals are primarily deposited in base of slope fans. The youngest of these turbidites is ca. 2600 years old. Sediment accumulation in these basins is low (<0.1 mm year−1) for basin adjacent to carbonate platform, possibly due to limited sediment input during highstand sea‐level conditions, sediment trapping and/or cohesive basin walls. We find no evidence of recent sediment transport (turbidites or debris flows) or sediment deformation that can be attributed to the ca. M7.2 1867 Virgin Islands earthquake whose epicentre was located on the north wall of the Virgin Islands Basin or to recent hurricanes that have impacted the region. The lack of significant appreciable pebble or greater size carbonate material in any of the available cores suggests that submarine landslide and basin‐wide blocky debris flows have not been a significant mechanism of basin margin modification in the last several thousand years. Thus, basins such as those described here may be poor recorders of past natural hazards, but may provide a long‐term record of past oceanographic conditions in ocean passages.

Submarine morpho-structure and active processes along the North American-Caribbean plate boundary (Dominican Republic sector)

The northern margin of Hispaniola records the oblique collision/underthrusting of the Bahamas Carbonate Province with the island-arc. Due to the collision, northern Hispaniola has suffered several natural disasters caused by major earthquakes and tsunamis, such as the historic earthquake of 1842, the tsunami caused by earthquake-driven slumping in 1918 in the Mona Passage, the seismic crisis of 1943-1953 with five events of M>7.0 or the seismic crisis of 2003 with a main shock of M6.3 and a large aftershock of M5.3. Using new swath multibeam bathymetry data and vintage single-and multi-channel seismic profiles, we have performed a regional scale analysis and interpretation of the shallow surface and active processes along the northern margin of the Dominican Republic. We have identified three morphostructural provinces: a) the Bahamas Banks, b) the Hispaniola Trench and c) the Insular Margin, which are divided into two tectonic domains, the Collision Domain and Underthrusting Domain. The southern slope of the Bahamas Carbonate Province shows a very irregular morphology produced by active erosive processes and normal dip-slip faulting, evidence of an extensional tectonic regime and margin collapse. This collapse is of major extent in the Oblique Collision Domain where there are erosive and fault escarpments with higher dip-slip fault throws. The Hispaniola Trench, is formed by the Caicos and Hispaniola basins in the underthrusting domain, and by the Santisima Trinidad and Navidad basins in the Oblique Collision Domain. They have a flat seafloor with a sedimentary filling of variable thickness consisting of horizontal or sub-horizontal turbiditic levels. The turbiditic fill mostly proceeds from the island arc through wide channels and canyons, which transports sediment from the shelf and upper slope. The Insular Margin comprises the Insular Shelf and the Insular Slope. The active processes are generated on the Insular Slope where the Northern Hispaniola Deformed Belt is developed. This Deformed Belt shows a very irregular morphology, with a WNW-ESE trending N verging imbricate thrust-and fold system. This system is the result of the adjustment of the oblique collision/underthrusting between the North American plate and the Caribbean plate. In the Oblique Underthrusting
