The glow returns to Mount St Helens

Last nights images from the Volcanocam showed the incandecent glow intermittently during last night. So it appears that fears of the early demise of the glow were unfounded... New processed movies of the glow have been posted.

The USGS/PNSN report that, "The mountain is clear today and emitting a moderate steam plume. Seismicity and deformation of the south part of the lava dome are proceeding at rates similar to those in the recent past. Digital analysis of recent aerial photography suggests that the overall rate of dome growth may have slowed down since late November. Later this week, field crews plan to install more GPS units near the vent area to measure extrusion rate."
