Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift northwestward to northeastward.

Recent observations: The volcano is visible this morning under high clouds. Seismic records show the low-level seismicity of ongoing lava-dome extrusion typical of the past many months. A magnitude 1 earthquake occurred yesterday afternoon at 14:35 PST. A signal on local recorders this morning at about 07:53 PST is arrival of an M7.7 tectonic earthquake with an epicenter in northern Chile.
