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 volcanic haze contains small quantities of ash, water vapor, sulfur aerosols, and liquid droplets suspended in the air. The main concerns for human health in volcanic haze consist of ash, sulfur dioxide gas (SO 2), and sulfuric acid droplets (H 2 SO 4), which forms when volcanic SO 2 oxidizes in the atmosphere. Volcanic haze can be both an ...
The eruption produced a voluminous and incandescent plume that rose 5,000 m (16,000 ft) above the vent and a probable short pyroclastic flow of approximately 2-3 km down the south and southeastern slopes of the volcano. The eruption lasted for six minutes and was followed by a relatively strong volcanic earthquake.
Geological mapping showed that much of the surrounding plains were formed by lahar flood deposits from previous eruptions. Volcanic activity increased throughout May. 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.
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.
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).

4 Classic Types Of Volcanoes. The eruption has been occurring within a closed area of Hawai'i Volcanoes ... The park’s volcanic activity can produce hazardous gases like sulfur dioxide, which ...
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 ...
