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.

Recent observations: Again it is sunny and clear today at the mountain. Partly sunny conditions are expected for the remainder day, allowing visual observations from the ground and air. Seismicity continues as very small periodic earthquakes, recurring every few minutes, punctuated by occasional larger but still small events. The large earthquakes are typically less than M3 and occur at a rate of less than 1 per day; there have been none of these in the last 24 hours. The active dome continues to build with motion to the west at about 1 meter per day, consistent with the trend established over the last two months. Monitoring instruments show no significant change in patterns of earthquake activity or deformation.
