Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise up to 7 km above sea level would drift broadly north in the morning, changing to northeast by afternoon. Ash that rises up to 12 km elevation would trend southeast in the morning and northeast in the afternoon.

Recent observations: The mountain is clear this morning, with partly cloudy conditions expected the remainder of the day. Our instruments show no significant change in patterns of seismicity or deformation. The GPS receiver on the new dome continues to plow westward at about a meter per day, the same rate it has had since its installment on the 24th of February. There are no changes in vent conditions as indicated by tilt stations on the old dome both northeast and northwest of the vent area.
