The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
The volcano released approximately 150,000 tonnes of CO 2 each day, or approximately 4.5 million tonnes of carbon dioxide by 19 April 2010. The massive reduction of air travel occurring over European skies caused by the ash cloud, saved an estimated 1.3 to 2.8 million tonnes of carbon dioxide from entering the atmosphere by 19 April 2010.

Two people wear hoodies and masks to shield themselves from the ash emitted by the Popocatépetl volcano in Atlixco, Mexico, on May 22, 2023. The volcano's activity has increased over the last ...
Mexico’s most dangerous active volcano spewed ash and smoke on Tuesday, with photos showing massive columns of gray emissions – large enough to ground nearby flights.
Volcano: Toba Caldera Complex: Date: c. 74,000 years BP: Location: Sumatra, Indonesia: VEI: 8: Impact: Covered the Indian subcontinent in 5 cm (2.0 in) of ash, [1] volcanic winter may have caused a severe human population bottleneck
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...
Volcanic ash deposits on a parked McDonnell-Douglas DC-10-30 during the 1991 eruption of Mount Pinatubo, causing the aircraft to rest on its tail.While falling ash behaves in a similar manner to snow, the sheer weight of deposits can cause serious damage to buildings and vehicles, as seen here, where the deposits were able to cause the 120 ton airliner's centre of gravity to shift.
The volcanic ash that could have brought KML Flight 867 crashing into the Talkeetna Mountains traveled 150 miles from the erupting Redoubt Volcano, according to a USGS fact sheet.
