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 broadly east-northeastward early in the day, switching to a southeastwardly trajectory later in the day.

Recent observations: Stormy weather envelopes the mountain this morning. A relatively large (probably M3+), shallow, near-surface earthquake at 11:19 am (PDT) yesterday generated a small dust plume (from rockfall) that rose above the rim. Such quakes, while now relatively rare, are not unusual for the type of ongoing dome-growth eruption occurring at the volcano.
