Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds rising above the crater today would drift slowly to the west today.

Recent observations: Small earthquakes accompanying lava dome extrusion continue to occur every 1-2 minutes, punctuated by occasional rockfall signals on seismic records. A large rockfall occurred yesterday evening at 4:59pm, producing a small ash cloud that could be seen from the Portland area.Views from the US Forest Service's web camera at the Johnston Ridge Observatory are clear this morning and show a small steam plume emanating from the new lava dome, as well as dust coming from minor rockfalls on the crater walls and the growing lava dome. Continued clear and hot weather today will make for excellent views of the ongoing eruption from the US Forest Service's visitor's centers at Coldwater Ridge and Johnston Ridge. Occasional sizeable rockfalls may produce ash clouds large enough to be visible from the Portland area.
