Mount St. Helens, USA (volcano Update)

Mount St. Helens, USA

Growth of the new lava dome inside the crater of Mount St. Helens continued during 8-15 February, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. Comparison of photos taken between 17 December and 7 February showed that the base of the active lobe of the lava dome enlarged by about 100 meters. A series of photographs taken during the week of 5 February showed that the active part of the new lava dome continued to extrude, with points on the surface of the dome moving a couple of meters per day. St Helens remained at Volcano Advisory (Alert Level 2); aviation color code Orange.
