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.
A dormant volcano or sleeping volcano is a volcano that has been quiet for a long time, but still has signs it may erupt again. A volcano becomes dormant when the vent is blocked by hardened lava, called a plug, or if the magma seeps back under the earthâs crust. Volcanoes can be dormant for hundreds of years.n practice, it is often impossible to distinguish between a dormant and an extinct volcano and several volcanoes thought to be extinct have subsequently re-erupted. Volcanoes can be dormant for hundreds or thousands of years and, due to the lack of eruptions, are usually eroded and worn down.
