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 northeast.

Recent observations This morning, cameras at Johnston Ridge Observatory are providing glimpses of the crater through intervening clouds. There have been no changes in background levels of seismicity or motion of the growing dome. Data from a GPS spider atop the dome, which fell over in early April and was righted on April 20, show that the rate of movement there has been constant since the spider was deployed in early February. Given a relatively wet weather forecast, no field work is planned for the remainder of this week.
