This is steaming from its summit fumaroles and 2009 lava dome, not ash. Redoubt remains at Aviation Color Code Green and Volcano Alert Level Normal. :)

We don't think so. There is no clear evidence at this time that the M6.2 earthquake or earlier earthquakes are volcanic in nature, nor is there any indication that this seismic activity has any direct implications for future eruptive activity at Takawangha or Tanaga volcanoes.

Infrasound (top) and spectrogram data from Shishaldin's eruption 1/19-1/20. The subaudible infrasound is mapped to human hearing range. You can hear short explosions spaced closely until 1/20 0000, changing to sustained jetting, with increased ash emission. David Fee UAFGI/AVO
