Possibly a major eruption.
The Mt St Helens cam has some great views todayhypatia said:Well I hope she wakes in a good mood.
Current status is Volcano Advisory (Alert Level 2); aviation color code ORANGE: Growth of the new lava dome inside the crater of Mount St. Helens continues, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.
Recent observations: The active part of the new lava dome continues to crumble and produce rockfalls and occasional ash clouds that rise above the crater rim. Crews plan to be in the field on Thursday and possibly Friday of this week to make a number of observations, to repair our voice radio-communications system, and to install a sensitive tiltmeter in a shallow borehole in the old lava dome. The latter is aimed at improving our understanding of the process of lava-dome extrusion.
