A huge volcano on the island of Tenerife has sparked fears of a HUGE eruption after nearly 100 mini earthquakes were reported in FOUR HOURS in the region.1teidThe Volcanology Institute of the Canary Islands (Involcan) reported a significant spike in seismic activity on Sunday afternoon. Some 92 microquakes were recorded in Adeje and Vilaflor in the space of four hours, with one measuring more than 1.5 on the Richter scale.

The majority of the quakes took place between 7 and 13km below ground sparking fears Mount Teide could be about to blow. Involcan has sent teams to the area to measure the amount of carbon dioxide in the atmosphere following the quakes, which they described as a “seismic swarm” which is “abnormal” for the region.

An increase in carbon dioxide is said to be an early indicator of volcanic earthquake activity that can precede an eruption. Involcan said in a statement: “We are registering an important seismic rally on the island of Tenerife. In principle, these earthquakes are very low magnitude, consistent with those that occur in active volcanoes.”

Mount Teide last erupted in 1909 and the last reported increase in seismic activity dates back to 2003 when a rift opened on the north-east of the volcano. The volcano, although dormant, is considered structurally unstable. The 12,000 ft Mount Teide is the highest peak in Spain and was declared a national park in 1954. Each year up to three million tourists visit the peak and its 80m wide crater.
