3. Water and carbon dioxide

Water and carbon dioxide are usually the most abundant gases emitted during basaltic volcanism.


The most abundant volcanic gas is water vapor. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes.

These gases could be potential hazardous to people, animals, agriculture, and property. [Source]
