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 be transported to the east.

Recent observations: A number of small earthquakes in the last 24 hours have triggered rockfalls that lasted 1-2 minutes, and some have been followed tens of minutes later by continued rockfall activity as the growing dome continues to fall apart and spread. The dust clouds produced by the rockfalls have not made it over the crater rim. No other significant new activity has occurred.
