Mount St Helens - something happened last night

At 20:39 last night there was a spectacular brightening of the glow on Mount St Helens. The glow which has been relatively quiet in recent days flared up to a level which has not been seen since it first appeared last October. This sudden burst of activity may have corresponded with a large piece of the lavadome breaking off exposing fresh lava to the air. Better weather over the coming days may enable USGS/CVO scientists to observe any major changes to the lavadome that have occured.
