The principal components of volcanic gases are water vapor (H 2 O), carbon dioxide (CO 2), sulfur either as sulfur dioxide (SO 2) (high-temperature volcanic gases) or hydrogen sulfide (H 2 S) (low-temperature volcanic gases), nitrogen, argon, helium, neon, methane, carbon monoxide and hydrogen.
The effects of volcanic eruptions containing sulfur dioxide aerosols on the ozone layer are complex, however. In the absence of anthropogenic or biogenic halogenated compounds in the lower stratosphere, depletion of dinitrogen pentoxide in the middle stratosphere associated with its reactivity to the aerosols can promote ozone formation.

an estimated 10–120 million tons of sulfur dioxide were emitted, produced the "Year Without a Summer" [23] 1808 ice core event: Unknown eruption near equator, magnitude roughly half Tambora: Emission of sulfur dioxide around the amount of the 1815 Tambora eruption (ice cores from Antarctica and Greenland). [24] 1808
The eruption was one of the most powerful of the 19th century, spewing so much sulfur dioxide into the stratosphere that annual average temperatures in the Northern Hemisphere dropped by about one ...
A volcanic eruption is essentially the only natural way for short-lived – less than a few years – gases like sulfur dioxide and water vapor to make it into the stratosphere.
Measurements of sulfur dioxide emissions showed a rapid increase from 500 t (550 short tons) per day by May 13 to 5,000 t (5,500 short tons) per day by May 28. [ 9 ] [ 8 ] This implied that there was a rising column of fresh magma beneath the volcano.
When volcanoes erupt, they eject carbon dioxide (CO 2), water, hydrogen, sulfur dioxide (SO 2), hydrogen chloride, hydrogen fluoride, and many other gases (Meronen et al. 2012). CO 2 and water are greenhouse gases, which comprise 0.0415 percent and 0.4 percent of the atmosphere, respectively.
The eruption of one the world’s most active volcanoes continues to captivate onlookers on Hawaii’s Big Island. ... The park’s volcanic activity can produce hazardous gases like sulfur ...
