Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift southward early in the day and southeastward later.

Recent observations: Seismicity and extrusion rates continue at roughly the levels of the past few days, with the largest earthquakes of the past 24 hours between magnitudes 1 and 2. Despite the overcast conditions in the Portland area, weather is partly cloudy to sunny at the volcano. Yesterday's wet weather increased the moisture in the crater and caused some periodic steaming of the old lava dome that was visible on the volcanocam this morning. Field crews working on the flanks of the volcano are conducting routine GPS geodetic surveys and running seismic experiments.
