Certain constituents of volcanic gases may show very early signs of changing conditions at depth, making them a powerful tool to predict imminent unrest. Used in conjunction with monitoring data on seismicity and deformation, correlative monitoring gains great efficiency. Volcanic gas monitoring is a standard tool of any volcano observatory ...
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...

Volcanic ash is typically a mixture of crushed-up solids – including rocks, minerals and glass – and gases, such as water vapor, carbon dioxide and sulfur dioxide, according to NASA.
Strombolian eruptions are a type of volcanic eruption named after the volcano Stromboli, which has been erupting nearly continuously for centuries. [13] Strombolian eruptions are driven by the bursting of gas bubbles within the magma. These gas bubbles within the magma accumulate and coalesce into large bubbles, called gas slugs.
First: volcanic arc, volcanic belt and volcanic zone. Second: volcanic area, caldera cluster and caldera complex. Third: volcanic field, volcanic system and volcanic center. A volcanic field is a localized area of the Earth's crust that is prone to localized volcanic activity.
Aerial footage showed streams of orange molten lava and clouds of gases spewing from a snaking fissure about 900 meters (half a mile) long. Tourists are told to stay away from an erupting volcano ...
Sampling gases at a fumarole on Mount Baker in Washington, United States Fumaroles at Vulcano, Sicily, Italy. A fumarole (or fumerole; from French fumerolle, a domed structure with lateral openings, built over a kitchen to permit the escape of smoke [2]) is an opening in a planet's crust which emits steam and gases, but no liquid or solid material.
