Sulfur is found in meteorites. R.W. Wood suggests that the dark area near the crater Aristarchus is a sulfur deposit. Sulfur occurs native in the vicinity of volcanos and hot springs. It is widely distributed in nature as iron pyrites, galena, sphalerite, cinnabar, stibnite, gypsum, epsom salts, celestite, barite, etc.
The higher the sulfur content of these gases, the closer the volcano is to erupting. Gas samples may be taken and chemical sensors used to measure sulfur levels. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate.Volcanoes such as Mount St Helens in the USA and Mount Etna in Italy are closely monitored at all times.This is because they have been active in recent years and people who live nearby would benefit from early-warning signs of an eruption.he higher the sulfur content of these gases, the closer the volcano is to erupting.
