1 Mount Teide is currently a dormant volcano, but many scientists believe it will erupt again in the near future. 2  In the mid seventeenth century a group of Englishmen were the first Europeans to reach the summit of Mount Teide. The most recent eruption of Mount Teide happened in 1909. 2  It also erupted in 1798, 1706, 1705 and 1704. 3  On his voyage of discovery Christopher Columbus apparently saw the 1492 eruption of Mount Teide when he was sailing past Tenerife.
Sleeping Giants. Volcanologists (geologists who study volcanoes) classify volcanoes as either active, dormant, or extinct. An active volcano is a volcano that is currently erupting or has erupted recently, such as Mount St. Helens, which most recently erupted in 1980.A dormant volcano is one that has not erupted recently but is expected to do so again. Prior to its 1980 eruption, Mount St. Helens had been classified as dormant.n extinct volcano is a volcano that volcanologists do not think will ever erupt again, such as Mount Buninyong in Australia. It is often difficult to determine which volcanoes are extinct and which are dormant.
