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 would be transported to the southwest all levels until late this afternoon. This evening lower level winds will continue to move ash to the southwest, but upper level winds (for ash column to 12 km) would blow to the northeast.

Recent observations: The crater is free of clouds this morning. The level and character of seismicity has not changed in the past 24 hours. Small earthquakes are still occurring at the rate of one every 1 to 3 minutes, indicating that lava extrusion is continuing. Rockfalls from the growing spine may be expected to occur sporadically in the foreseeable future. Ventings of steam associated with larger rockfalls this past week have lofted ash to about 15,000 feet.
