These characteristics make sulphur dioxide a good target for volcanic gas monitoring. It can be detected by satellite-based instruments, which allow for global monitoring, and by ground-based instruments such as DOAS. DOAS arrays are placed near some well-monitored volcanoes and used to estimate the flux of SO 2 emitted.
An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future. [1] A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. [1]
Volcanoes that are not currently active, but may be either dormant or extinct or of otherwise uncertain inactive volcanic status. Wikimedia Commons has media related to Inactive volcanoes . Subcategories
Volcanoes vary greatly in their level of activity, with individual volcanic systems having an eruption recurrence ranging from several times a year to once in tens of thousands of years. [76] Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform among ...
Mount Gambier is one of Australia's youngest volcanoes, but estimates of the age have ranged from over 28,000 to less than 4,300. [1] The most recent estimate, based on radiocarbon dating of plant fibres in the main crater suggests an eruption a little before 6000 years ago. [1] [2] It is believed to be dormant rather than extinct.
Two long-dormant “supervolcanoes” on two separate continents appear to be stirring to life. Well, maybe. In recent months, more than a thousand minor earthquakes have rattled the area around ...

Volcanoes known to have Surtseyan activity include: Surtsey, Iceland. The volcano built itself up from depth and emerged above the Atlantic Ocean off the coast of Iceland in 1963. Initial hydrovolcanics were highly explosive, but as the volcano grew, rising lava interacted less with water and more with air, until finally Surtseyan activity ...
