Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds that rise above the crater rim today would drift south-southeastward early and broadly southward to eastward later.

Recent observations: The crater is clear this morning, and images from the USGS camera at the crater mouth show that the dome continues to grow. Seismic and deformation data continue trends of the past few weeks. Tomorrow if the weather cooperates, field crews plan to install and retrieve instrumentation packages in the crater, conduct GPS surveys on the volcano's flanks, collect water samples, and service flow-warning instrumentation at the mouth of the crater.
