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-northwestward early in the day, and switch to a more northwestward drift later in the day.

Recent observations: Field instruments indicate that the lave dome continues to grow at a rapid rate. The view from the VolcanoCam this morning shows the crater partly filled with clouds and steam. If the weather improves sufficiently, we may attempt to obtain new aerial photographs of the lava dome. Otherwise, we have no field plans for today. If weather permits, field crews plan to measure gas, install new GPS, take new photographs, and collect a rock sample later in the week.
