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 ...
English: Average carbon dioxide (CO2) emissions of subaerial volcanoes globally from the time period of 2005 to 2017. This includes emissions from volcanic crater and does not include diffuse degassing emissions. It also shows emissions during passive degassing, i.e. not during eruptions.
Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Volcanism, vulcanism, volcanicity, or volcanic activity is the phenomenon where solids, liquids, gases, and their mixtures erupt to the surface of a solid-surface astronomical body such as a planet or a moon. [1]
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.

The last time Campi Flegrei erupted was in 1538, and one of the system’s biggest explosions occurred around 39,000 years ago.. In September, the former head of the Vesuvius observatory at Italy ...
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.
