Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift north-northeast.

Recent observations: A lava dome continues to grow within the crater accompanied by small earthquakes and rockfall activity. An earthquake of magnitude 3.0 and ensuing rockfall on Friday late morning sent dust up to the rim briefly. Two other smaller earthquakes (M1.1 and M2.2) have occurred in the past 24 hours.
