Current Stromboli status from INGV, translated via Google:
Official notice of 13-9-2007
Modernization to the hours 12,00 premises
(the hour ones specify to you in the text are all GMT)In the day odierna on the Island of Stromboli 2 units of staff INGV are present that operate
within four fields of monitoring: Volcanology, Sismologia, Geochemistry and Deformations.The data supplied in last the 24 hours from the nets of monitoring of the deformations of the ground (nets GPS and Topographical) istallate on the island do not show meaningful variations regarding the trend record i to you previous days.
The images of the infrared television camera mail on the Peak over the Fossa, in last the 24 hours, have shown one optimal visibility of the craterica area from the hours 17:22 of day 12.
The explosive activity has been produced mainly from following the mouths:
- in the northern portion of the craterica area two mouths have produced outbreaks of rough material (lapilli and bombs). The mouth mails on the northern hem of the area craterica has produced to outbreaks with one frequency of 2-3/h and height <80 m while mouth mails in inner position regarding the previous one has produced outbreaks with one medium height and frequency 5-6/h < 150 m (i project of some outbreaks have exceeded i 200 m).
- in the portion sporadic activity of launch of brandelli centers them a mouth has shown one of
it washes.
- in the southern portion of the craterica area a mouth has produced medium 3 esplosioni/h of ash diluted of medium height < 150 m before being taken in cargo from i twenty dominant.
The thermal television camera of 190 quota s.l.m and the visible one of quota 400, in last the 24, do not have shown changes meant to you regarding the previous days neither of the area they of the Sciara centers of Fire before, neither of northern the part sommita them of the volcano the second one. From the television camera visible of quota 400, they have been observed the more energetic ash outbreaks and the activity of degassamento of the craterica area.
The data from 12 of the 13 stations are acquired that compose the net. The recorded sismica activity in the last ones 24h it has introduced following characteristic (times GMT):
• The visual analysis of the sismogrammi has not evidenced marks them sismici combinable to events franosi.
• The amplitude of the vulcanico tremor oscillates on a lower-middle level.
• Conteggio of the Very events the Long Period (VLP) it has supplied an equal value to approximately 12 events/hour.
• The amplitude of marks them VLP is on a low level.
• Localization of the source of marks them VLP, by means of analysis of the semblance, indicates that the ipocentrale depth is comprised between 400 and 500 m s.l.m.
• Some events of type LP Are present.
The analysis of the acquired geochimici parameters in last the 24 hours, through the monitoring net continuous and the discreet measures, are of synthetized continuation:
• The temperature of the measured ground to 50 cm of depth from station SST02, located to
Peak Over the Fossa, extension stable values. The measured temperature is around to the 70°C.
• The flow of CO2 from the ground measured from Station STR02 mails on the Peak over the Fossa extension a every day medium value of 5900 g m-2 d-1 in last the 24 hours. One are found light increment regarding the acquired medium values in the last period.
• The flow of SO2 measured from net FLAMES in the day of the 12 September is of approximately 180 t/d.
• Not there are modernizations of relationship C/S of the plume of Stromboli.
