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 to the northeast in the morning then shift to a more north-northeast trajectory in the afternoon.

Recent observations: Unsettled weather continues at the mountain today. Instruments show no significant change in patterns of seismicity or deformation. Seismicity continues as series of small earthquakes every two to three minutes, punctuated by an occasional larger earthquake, e.g., a > M2 event at 22:23 PST Tuesday night. The active dome continues to build with motion to the west at about 1 meter per day, on-trend with recent observations. Monitoring data are within the range of typical recent values
