Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim today would drift north-northeastward early in the day, and swing southeastward later in the day.

Recent observations: This morning, clouds obscure the mountain, and no field work is planned for today. Overnight a few more earthquakes of about magnitude 2.5-3 occurred amidst the ongoing pattern of frequent smaller earthquakes. Such swarms have occurred on several occasions during the past month and are not unusual given the nature of the eruption. Results from the gas-sensing flight on Friday are still being processed and will be made available once processing is complete.
