In explosive volcanic eruptions, the sudden release of gases from magma may cause rapid movements of the molten rock. When the magma encounters water, seawater, lake water or groundwater, it can be rapidly fragmented. The rapid expansion of gases is the driving mechanism of most explosive volcanic eruptions. However, a significant portion of ...
The eruption triggered the sudden release of about 100,000–300,000 tons of carbon dioxide (CO 2). [2] [3] The gas cloud initially rose at nearly 100 kilometres per hour (62 mph; 28 m/s) and then, being heavier than air, descended onto nearby villages, suffocating people and livestock within 25 kilometres (16 mi) of the lake.

Lake Nyos (/ ˈ n iː oʊ s / NEE-ohs) [1] is a crater lake in the Northwest Region of Cameroon, located about 315 km (196 mi) northwest of Yaoundé, the capital. [2] Nyos is a deep lake high on the flank of an inactive volcano in the Oku volcanic plain along the Cameroon line of volcanic activity.
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.
The first helicopter overflight of Kīlauea's new SW rift zone eruption site at 6 AM HST on June 3, 2024 showed lava fountaining from 1 km (0.5 mi)-long fissures and volcanic gases blowing downwind.
Sulfur monoxide has been detected around Io, one of Jupiter's moons, both in the atmosphere [15] and in the plasma torus. [16] It has also been found in the atmosphere of Venus, [17] in Comet Hale–Bopp, [18] in 67P/Churyumov–Gerasimenko, [19] and in the interstellar medium. [20] On Io, SO is thought to be produced both by volcanic and ...
A volcanic eruption in Iceland close to the capital Reykjavik is slowing, experts said on Tuesday, hours after officials had warned it was spewing out "life-threatening toxic gas". Icelandic ...
The pipes over which they are standing serve to guide sulfur vapors and condense them, thereby facilitating production. [2] The Ijen volcano complex is a group of composite volcanoes located on the border between Banyuwangi Regency and Bondowoso Regency of East Java, Indonesia. It is known for its blue fire, acidic crater lake, and labour ...
