Authorities drop Galeras volcano alert to orange

Thursday, 26 August 2010 06:32 Kirsten Begg

Colombia's Institute of Mining and Geology (Ingeominas) on Wednesday night lowered the alert on the Galeras volcano in the south-western department of Nari?o from red to orange.

Ingeominas director Mario Ballesteros said the warning had been reduced because the volcano's activity had stabilized, but stressed that local residents should remain on alert. An orange alert means an eruption is expected in days or weeks.

The Colombian air force "was able to fly over [the volcano] and in the middle of the cloudiness observed gases and ashes exiting numerous sectors of the active cone," Ballesteros said.

On Wednesday afternoon only some 300 of the region's 8,000 residents had evacuated the area surrounding the volcano, despite calls from the government to do so.

Seismic activity continues but alert remains at "Orange"

Summary of the text in Spanish: Activity continues after a "low explosivity" eruptive episode on the 25th of Aug, triggering the initial "red" alert and characterized by a broad column of gases and rock emitted ballistically, seismic activity continues.

On August 30, 2010, 1:15 PM, a Magnitude 4.0 Richter, seism impacting Pasto and several other communities was recorded. Volcanic activity continues to fluctuate, particularly in terms of energy and including events of fracture of the volcanic "building" structure and magma flow [It is not clear if this is an outflow of lava].

Between the 26th, when the alert was downgraded to "orange," and the 31st of August there have been 12 tremors, hence the continued alert level.
