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 broadly southward at low altitudes and south-southeastward at higher altitudes.

Recent observations: Conditions remain largely unchanged from those of the past few days—frequent small earthquakes and occasional larger ones, as well as rockfalls accompanied by minor ash clouds from the growing lava spine. Repeat photographs from the DomeCam shows that the lava spine is moving slightly westward and, in response, the adjacent northeastern part of the new dome is sagging slightly toward it.
