According to CVO, during 3-8 November, seismicity at Mount St. Helens remained at a low level compared to early in the unrest. The seismicity during the report period was consistent with a continuing, slow rise of magma driving uplift of the crater floor and feeding a surface extrusion of lava. The overall low rates of seismicity and gas emission suggested that the lava reaching the surface was gas poor, thereby reducing the probability of highly explosive eruptions in the near term.

Activity at Mt St Helens is persistent and evolving. VolcanoWorld directs you to the following websites for the most up to date information
