Lava dome growth at Mt St Helens volcano paused in late January 2008, after more than 3 years of activity. Over the past few weeks no extrusion of lava has been detected. The lava dome is still hot and may form hot avalanches and steam explosions. Melting of snow could produce lahars. Seismicity is at very low levels at the volcano. Gas emissions are barely detectable, and daily ground-tilt events have stopped. The volcano alert level has been reduced from orange to yellow.
