Mt. Fitzherbert
USGS Update 2006-Jan-18 11:30
Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim would drift to the east (ENE to ESE) throughout the day.
Recent observations:The lava dome in the crater of Mount St. Helens continues to grow as lava is slowly extruded, accompanied by periodic small earthquakes. Progress of the eruption currently is tracked by seismometers, GPS receivers, and tiltmeters, which transmit to the observatory continuously. Aside from an infrequent, limited view of the mountain caught by the USFS webcam, we have had no visual observations of the crater in the 31 days since December 18, 2005, owing to stormy winter weather.
