Hi Theodore - There are quite a few reasons why you could smell sulfur, and most of them are not volcanic. When you say "smelling sulfur", do you mean it smells like rotten eggs, or like a burning match? If rotten eggs, sewage somewhere is the most likely culprit. There are volcanoes on St. George, although they have not been active for thousands of years. The volcanoes on St. Paul are younger. Thank you, Cheryl Cameron -------- Theodore Lekanof wrote: I would like to know as to why we are smelling sulfur here on St. George Island. One minute we smell it then later on the day it's gone. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
