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 today would be transported to the east-southeast.

Recent observations: Several minor rockfalls occurred overnight, alongside the regular “drumbeat” earthquakes. Occasional rockfalls, some of appreciable size that may produce dust clouds reaching over the crater rim, are to be expected as the new dome continues to grow and fall apart. Weather permitting, field crews hope to put in a full day of work around the volcano today. Items on the to-do list include retrieving a number of damaged seismic and GPS instruments in the crater (including several “spiders”), installing several replacement seismic “spiders”, deploying a number of temporary GPS instruments on the flanks, perform water sampling surveys, and other work as time allows.
