Mt. Fitzherbert

Nighttime timelapse taken 2005-Aug-12

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 eastward to east-southeastward.

Recent observations: Occasional large quakes and associated rockfalls continue to occur, the most recent (~M3) at 8:52 this morning. Ash plumes associated with rockfalls typically rise above the rim and quickly dissipate. Otherwise, seismicity and deformation remain largely the same as in the past several days. Analysis of a digital elevation model from July shows that the volume of the new dome is about 58 million cubic meters (76 million cubic yards), almost 75 percent of the volume of the 1980s lava dome. The new dome continues to grow at a rate of about 1.3 cubic meters per second (almost 2 cubic yards per second).
