Galeras Update for 8/28/07

Current Galeras status from INGEOMINAS, translated via Google:

PRESS OFFICIAL NOTICE – REFERENCE: REPORT OF ACTIVITY OF THE VOLCANO
GALERAS, 27 of August of 2007 (6: 50 p.m.)

The activity of the volcano stays in:

Level III (CHANGES IN the BEHAVIOR OF the VOLCANIC ACTIVITY)

From the permanent pursuit and analysis that the Vulcanológico Observatory makes of
INGEOMINAS in Grass, stands out that:
¨ stays the occurrence of events related to transit of flowed to the interior of the system
volcanic. In the last week the occurrence of small events has been increased, of character
superficial.
¨ the located electronic clinometers in the top, maintained the tendency that brought from
previous weeks.
¨ Azufre Dioxide emissions stay (SO2) in levels significant, similar to the reported ones
in the previous official notice. The column has dispersed preferential towards the flank
noroccidente by action of winds.

INGEOMINAS continues kind to the evolution of the volcanic activity and will inform opportunely
changes that can be detected

Galeras Weekly Update for 8/13/07

Current weekly status report for Galeras from INGEOMINAS, translated via Google:

PRESS OFFICIAL NOTICE – REFERENCE: REPORT OF ACTIVITY OF THE VOLCANO
GALERAS, 13 of August of 2007 (7: 10 p.m.)

The activity of the volcano stays in:

Level III (CHANGES IN the BEHAVIOR OF the VOLCANIC ACTIVITY)

From the permanent pursuit and analysis that the Vulcanológico Observatory makes of
INGEOMINAS in Grass, stands out that:
♦ During the last week increased the number of events associated with transit of flowed to the interior of the volcanic conduits, but its energy diminished with respect to the considered thing for the week immediately previous. However, the energy of events related to rock fracture, registered considerable increase, mainly by the occurrence of the earthquake of Local Magnitude 3.2 of August 6, that it was mentioned in the official notice of the previous week.
♦ the located electronic clinometers in the top, showed the same tendency that brought from
previous weeks.
♦ day 6 of August was made measures of Dioxide of Azufre (SO2) in the highway encircle,
specially towards sector NW of the volcano, which reached a maximum value of 326 ton/day, that it is considered low quantitatively.

INGEOMINAS continues kind to the evolution of the volcanic activity and will inform opportunely
changes that can be detected.

Galeras Weekly Update for 7/23/07

Weekly update for Galeras From INGEOMINAS:

PRESS OFFICIAL NOTICE – REFERENCE: REPORT OF ACTIVITY OF THE VOLCANO GALERAS, 23 of July of 2007 (5: 50 p.m.)
The activity of the volcano stays in:
Level III (CHANGES IN the BEHAVIOR OF the VOLCANIC ACTIVITY)

From the permanent pursuit and analysis that the Vulcanológico Observatory of the INGEOMINAS makes in Grass, one stands out that:
¨ the energy and the number of earthquakes registered in the last week, showed values low, quantitatively similar to which was handled before the seismic cluster happened between 5 July and July 9 of 2007.
¨ Predominaron events related to the dynamics of the magmatic fluids, some of which can be associated with processes of gas liberation. Between the earthquakes registered in this week, the event stands out Screw of July 21 (05: 41 p.m.).
¨ Measurements of conducted the Sulfur Dioxide emanations in July 19, maintained values similar to the measured ones in the previous week.
¨ two sobreflights of recognition were made, in one from which it obtained thermal images of the active cone, which they showed values of temperature of the rock which they are relatively similar to those obtained earlier this year. The gas discharge, continues appearing by several points of the periphery of the main crater and from the bottom of he himself.

INGEOMINAS continues kind to the evolution of the volcanic activity and will opportunely inform the changes that can be detected.

Galeras Weekly Update for July 8-16, 2007

Current Galeras status, translated via Google from INGEOMINAS:

REPORT OF ACTIVITY OF THE VOLCANO GALERAS, 16 of July of 2007 (6: 10 p.m.)

The activity of the volcano stays in: Level III (CHANGES IN the BEHAVIOR OF the VOLCANIC ACTIVITY)

From the permanent pursuit and analysis that the Vulcanológico Observatory of the INGEOMINAS makes in Grass, one stands out that:

♦ the increase in the seismicity of Galeras reported in both communicated previous, stayed until afternoon of the 9 of July, when gradually a disminuición of the registered earthquakes began, as much in occurrence as in energy.

In the last days the seismicity maintains low levels, with predominance of events related to dynamics of the magmatic fluids, some of which they are related mainly to processes of gas liberation. Between the earthquakes registered in this week, 4 have been observed Tornillo type, the last one of which it appeared 14 of July the past (to 06:05 a.m.).

♦ Measurements of the Sulfur Dioxide emanations conducted day 12 of July, maintain an increase with respect to the values that came measuring from end of the 2006, reflecting with this greater liberations in relative terms.

♦ the climatic conditions in the top, have prevented to make flights. INGEOMINAS continues kind to the evolution of the volcanic activity and will opportunely inform the changes that can be detected.
