Mt. Fitzherbert

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 east-northeastward.

Recent observations: Overnight, three large earthquakes of about magnitude 3 occurred amidst the ongoing sequence of smaller (mostly less than M1.5) earthquakes. This mini-burst of large earthquakes is similar to others that have occurred episodically in the past several weeks. Such a pattern represents nothing unusual in the expected sequence of events accompanying lava-dome growth. No field work was undertaken yesterday and none is planned today. In the coming days, field crews will conduct visual and hydrological observations, replacement and maintenance of seismic equipment, and gas and thermal-imaging measurements as weather permits.
