Saba and St. Eustatius (‘Statia’) are volcanic islands in the Caribbean Netherlands (Dutch Carribean). Due to subduction of the North and South American Plates under the Caribbean Plate, this region still has active volcanoes. The KNMI (Koninklijk Nederlands Meteorologisch Instituut) uses the PolaRx5S GNSS receivers to monitor the activity of volcanoes Mt. Scenery on Saba and The Quill on St. Eustatius.
GNSS observations are well suited to help monitoring active volcanoes.
