Lesser Antilles - Geology

Geology

The Lesser Antilles more or less coincide with the outer edge of the Caribbean Plate. Many of the islands were formed as a result of the subduction of oceanic crust of the South American Plate under the Caribbean Plate in the Lesser Antilles subduction zone. This process is ongoing and is responsible not only for many of the islands, but also for volcanic and earthquake activity in the region. The islands along the South American coast are largely the result of the interaction of the South American Plate and the Caribbean Plate which is mainly strike-slip, but includes a component of compression.
