Vog is created when volcanic gases (primarily oxides of sulfur) react with sunlight, oxygen and moisture.The result includes sulfuric acid and other sulfates. [4] Vog is made up of a mixture of gases and aerosols which makes it hard to study and potentially more dangerous than either on their own.
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 ...
After a volcanic eruption, evaporation over ocean will lower, because it is largely determined by the ocean surface temperature change. The quick response of evaporation to the surface cooling and the delayed response of river runoff to the associated lower precipitation lead to an increased sea level.
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 conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
You can’t breathe in there," said evacuated resident Robynn Stagg, 58, who drove through the thick, orange sulfur dioxide haze earlier this week in a failed attempt to check on her home.
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 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 ...
