During the same time interval, CO 2 emissions from volcanoes during eruptions were estimated to be 1.8 ± 0.9 Tg per year [10] and during non-eruptive activity were 51.3 ± 5.7 Tg per year. [10] Therefore, CO 2 emissions during volcanic eruptions are less than 10% of CO 2 emissions released during non-eruptive volcanic activity.
The massive explosive eruption was hundreds of times more powerful than the atomic bomb dropped on Hiroshima. A volcanic eruption could just be a simple outpouring of material onto the surface of a planet, but they usually involve a complex mixture of solids, liquids and gases which behave in equally complex ways.

Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
Ubinas is a major source of volcanic carbon dioxide and sulfur dioxide in the atmosphere of Earth, producing SO 2 at a rate of about 11.4 ± 3.9 kilograms per second (1,510 ± 520 lb/min). [118] The sulfur dioxide output changes with volcanic activity. [119] Reportedly, the sound of the fumaroles can be heard from the village of Ubinas. [120]
The 1991 eruption rated 6 on the Volcanic Explosivity Index and came some 450–500 years after the volcano's last known eruptive activity. The eruption ejected about 10 km 3 (2.4 cu mi) of material, making it the largest eruption of the 20th century since that of Novarupta in 1912 and some ten times larger than the 1980 eruption of Mount St ...
The eruption reached 3 on the Volcanic Explosivity Index. [25] The mass of the ejected sulfur dioxide was about 700,000 metric tons, or about two percent of the mass of the erupted solid material, [14] making the eruption unusually sulfur rich. [26]
The Met Office has said it is monitoring a cloud of sulphur dioxide which passed over the UK after a volcanic eruption in Iceland. The “plume” of gas is understood to have begun passing over ...
During the Little Ice Age, volcanic eruptions produced ashes that blocked solar insolation. The Earth surface received less radiation, the temperature decreased significantly. The effect lasted for around 6–8 years (Fig. 5). [23] In addition, sulfur dioxide produced from eruptions reacted with the ozone layer to form sulfuric acid. Fine ...
