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 north-northwestward to northward. Under these conditions, Johnston Ridge and the east end of Highway 504 could receive ash fall.

Recent observations: Clouds obscure the crater this morning. Although seismicity remains unchanged over the past several days and GPS units on the older part of the new dome show little movement, thermal observations and images from a camera at the mouth of the crater show that the western end of the dome continues to grow.
