An extinct volcano by definition is a dead volcano, which has not erupted in the last 10,000 years and is not expected to ever erupt again. In other words, an extinct volcano implies that there is no magmatic, seismic or degassing activity going on at the volcano and that it’s not expected to erupt again in a comparable time scale of the future.
• A volcano in Russia may be active again and scientists are worried that it could have “catastrophic” consequences1
• Iceland fears dormant volcano may be waking up2
• Previously extinct volcano raised to eruption warning level in Colombia: eruption would be first in recorded history3
• Dormant volcanoes from around the world are coming to life for the first time in 160,000 years4
• Fourth dormant volcano shows earthquake on the West Coast — Mammoth Mountain California5
More importantly, unrest is growing right now among some of the world’s Super-volcanoes like Laguna del Maule in Chile and Italy’s Campi Flerei — under the city of Naples. Since 2005, Campi Flegrei has been undergoing what volcanologists call an uplift. Campi Flegrei showing signs of reawakening, Italy6
The Campi Flegrei may be nearing a critical pressure point necessary to drive an eruption for the first time in 500 years, according to scientists. The pace of ground deformation and low-level seismic activity has recently increased and they are similar to two other active volcanoes – Rabaul in Papua New Guinea and Sierra Negra in the Galapagos – ‘both showed an acceleration in ground deformation before eruption with a pattern similar to that observed at Campi Flegrei,’ said one Italian geophysicist.
