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 northeastward, although early in the day at high-elevation they would drift broadly eastward.

Recent observations: The volcano is clear this morning affording good views of the newly growing lava dome. The actively emerging slab of solidified lava can be seen as the highest hump on the left side of the snow-free mass. Seismicity continues to be relatively quiet, with a steady background of small quakes occasionally punctuated by a moderate-sized earthquake, such as at 11:49 p.m. yesterday and 7:40 a.m. today. GPS data show that a part of the active dome continues to move slowly westward at about a meter per day.
