El vulcanismo en guinea ecuatorial y los peligros naturales asociados
Contenido principal del artículo
Resumen
Se resumen en este artículo las principales amenazas geológicas asociadas al vulcanismo activo de la Línea Volcánica de Camerún en la que se inserta la región insular de la República de Guinea Ecuatorial (islas de Bioko, Annobón (Pagalú), Corisco, Elobey Grande y Elobey Chico) y se pasa revista a la actividad tectónica reciente de esta importante estructura geológica. Se mencionan algunas de las medidas estructurales y no estructurales a considerar para la reducción de la vulnerabilidad volcánica del territorio.
