Face to Face from 5000km?
Isnt 5000km the complete opposite of Face to Face?
SO2 and CO2 are about 5 - 10 times normal (for Iliamna) and a bit higher than the maximum levels detected in 1996. This points to a magmatic intrusion, but remember that not all intrusions result in eruptions. Most don't.
So here we have me, Mr. Fearmongering, Triggerhappy Alerthog, laughing at scientists because THEY raised the alert on a volcano that has lots of bark, but no bite!
A flight to measure levels of gas emission and make visual observations of the summit area occurred on Saturday, March 17. Data from the flight indicate that the volcano is emitting elevated levels of sulfur dioxide and carbon dioxide, consistent with a magmatic source. It is not known, however, if this is a newly intruded magma, or whether new pathways for gas from preexisting magma have caused the increased gas flux. The amount of gas being emitted is broadly similar to levels seen in 1996-1997, when a likely magmatic intrusion but no eruption occurred at the volcano.
Observers on the flight saw vigorous and plentiful fumaroles (gas vents) at the volcano's summit, consistent with the elevated gas emissions. No obvious signs of recent rockfall, large areas of newly exposed bedrock, or unusual disturbance of the glacial ice were observed. Some deformation of the ice at the headwall of the Red Glacier on the east side of the summit was seen, but it is not clear whether this is related to the current volcanic unrest; avalanching of the glacier is common on this very steep area and was last seen in 2008.
