There are growing fears among residents in Tenerife that Mount Teide may become active in the near future, after a number of tremors were registered during the weekend.
Mount Teide, which measures 7,500ft from its ocean floor base, has been dormant for over 100 years. There was a partial eruption through one of its vents in 1909, and the last time its summit erupted was way back in 850 CE.
But this past weekend, seismic sensors registered a large amount of activity around the site, and a higher than normal amount of carbon dioxide has been released into the air. CO emission usually precedes volcanic activity.
Local authorities are closely monitoring the situation, while residents call for evacuation plans to be drawn immediately.
