The 1867 Virgin Island tsunami was of a great effect for the Caribbean Islands. A maximal tsunami height of 10 m was recorded for two coastal locations (Deshayes and St. Rose) in Guadeloupe.

RésuméLe tsunami de 1867 des Îles Vierges a eu un grand effet sur les îles de la Caraïbe. Deux vagues de tsunami d'une hauteur maximale de 10 m ont été enregistrées en deux points des côtes de la Guadeloupe (Deshaies et Sainte-Rose). Les données historiques de cet événement pour la mer des Caraïbes sont discutées. La modélisation du tsunami de 1867 est effectuée dans le cadre de la théorie non linéaire en eau peu profonde. Les quatre orientations possibles de la source du tsunami dans le passage d'Anegada sont étudiées. La directivité de la vague de tsunami dans la Caraïbe est examinée. Les fluctuations temporelles de la surface de la mer sont calculées pour plusieurs points de la côte de la mer des Caraïbes. Les résultats de la simulation numérique sont raisonnablement en accord avec les données d'observation.
Abstract. The 1867 Virgin Island Tsunami reached large magnitude on the coasts of the Caribbean Islands. A maximum tsunami height of 10 m was reported for two coastal locations (Deshaies and Sainte-Rose) in Guadeloupe. Modelling of the 1867 tsunami is performed in the framework of the nonlinear shallow-water theory. The directivity of the tsunami wave source in the Caribbean Sea according to the assumed initial waveform is investigated. The tsunami records at the several coastal regions in the Lesser Antilles, Virgin Islands, Puerto Rico and South America are simulated. The comparison between the computed and observed data is in reasonable agreement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
