Mt. Fitzherbert

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

Recent observations: The Forest Service's VolcanoCam shows that the volcano is clear and emitting a diffuse vapor and ash plume from the growing lava dome. Yesterday morning, collapse of a rock column on the dome's northeast face created a photogenic cloud that sent a minor plume of ash rising above the rim. A sequence of before, during, and after photos is posted on the USGS website. Gas measurements yesterday show that the volcano continues to emit very low levels of sulfur dioxide (SO2) and carbon dioxide (CO2), showing that magma driving the eruption remains gas poor. Seismicity remains at the recent typical level of one small earthquake (~ M1) every few minutes with smaller events occurring more frequently.
