PRESS OF 14/12/2007
(Updated at 09:00 local time)This press is on the analysis of seismic signals, carried out in the hall monitoring INGV section of Naples (Osservatorio Vesuviano), where the signals are centralized network a large seismic Banda who works on Stromboli.
Currently acquired data from 10 of the 13 stations that make up the network. The seismic activity registered in the last 24 hours has submitted the following characteristics (GMT times):
• An analysis of the seismograms showed no signs associated with seismic events.
• The amplitude volcanic tremor is a medium value, with a rising trend.
• The counting of events Very Long Period (VLP), gave a value of about 14 events per hour.
• The amplitude of the signals on VLP is low.
• The location of the source signal VLP through analysis of semblance indicates a depth ipocentrale within the 400 m-500 m asl
• The parameters of seismic signal polarization in Banda Frequency VLP are disturbed the high level of seismic noise low frequency of marine origin.
• The magnitude of explosion-quakes ranged between low and medium.
