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 south-southwestward early in the day and south-southeastward later.

Recent observations: No significant changes in patterns of earthquakes or ground deformation have occurred over the past day. A series of photographs taken from a fixed point on the old lava dome last week over a 2.5-hour period showed that the active part of the new lava dome continues to extrude; points on the surface of the dome are moving a couple of meters per day. Crews are heading to the field today to make thermal and photographic observations, to measure gas flux, and to make some repairs to antennas and power systems at several monitoring sites. More field work is planned for tomorrow.
