==Geology==
The islands are located on the Cayman Rise which forms the northern margin of the Cayman Trough. The trough is the deepest point in the Caribbean Sea and forms part of the tectonic boundary between the North American Plate and the Caribbean Plate. The Cayman Rise extends from southeastern Cuba along the northern margin of the Cayman Trough toward Costa Rica and resulted from Paleocene to Eocene island arc formation with associated volcanism along an extinct subduction zone.〔(H. Sigurdsson, et al., ''History of circum-Caribbean explosive volcanism: 40Ar/39Ar dating of tephra layers,'' Ch. 20 in ''Volume 165, Proceedings of the Oceanic Drilling Program,'' 26 May 2000, ISSN 1096-7451 ) 〕 The islands are formed of marine limestone and dolostone that was uplifted during the late Miocene epoch.〔J.E. Davies and M.A. Brunt (1994), "Scientific Studies in the Cayman Islands", in: (''The Cayman Islands: Natural History and Biogeography'', Volume 71 ), edited by M. A. Brunt. Springer. p. 1. ISBN 9780792324621.〕 Due to the Islands location, the Cayman Islands do get Earthquakes.
