Mt. Fitzherbert

Recent observations: Scientists from the Cascades Volcano Observatory continue to monitor the volcano remotely. No fieldwork was done this past week, but several crews will be out next week for geologic mapping, maintenance of seismic stations and acoustic flow monitors (AFMs), and collecting photogrammetry control points. The past week's seismic record is dominated by rockfalls in the crater during this hot, dry weather and by glaciogenic earthquakes as the glaciers continue to flow northwards.
