Bathymetry of the northeast corner of the Caribbean plate

Figure 1. Bathymetry of the northeast corner of the Caribbean plate. The main topographic features of this area include: the Lesser Antilles volcanic arc, the old inactive volcanic arc of the Greater Antilles (Virgin Islands to Hispaniola), and the Caribbean and North American oceanic plates. Note that the Puerto Rico Trench, a deep trough where the North American plate slides past and underneath the Antilles, becomes deeper and wider north of Puerto Rico. A limestone platform is tilted toward the trough in this area. Other large-scale features are the Muertos Trough, where Caribbean plate crust may slide under the Antilles, and the Virgin Islands and Anegada Trough, whose origin is unknown.
