<P> The volcano is closely monitored by the Osservatorio Vesuvio in Naples with extensive networks of seismic and gravimetric stations , a combination of a GPS - based geodetic array and satellite - based synthetic aperture radar to measure ground movement and by local surveys and chemical analyses of gases emitted from fumaroles . All of this is intended to track magma rising underneath the volcano . No magma has been detected within 10 km of the surface , and so the volcano is classified by the Observatory as at a Basic or Green Level . </P>
