BRITS off to Tenerife are being warned of the danger of a massive volcano eruption.
Experts are worried about “semi-volcanic activity” in 12,200ft Mount Teide — Spain’s highest peak.
Tenerife, largest of the Canary Islands, does not have evacuation plans if there is an eruption.
Scientist Dr Alicia Garcia said: “Tenerife is our great worry and problem.
“The Canary Islands have become very vulnerable because of the high level of tourism.”
About 1.5million Brits visit Tenerife each year and many take the cable car up Mount Teide.
It erupts around once every 100 years — and the last was in 1909.

Wow, if that mountain fall into the sea, East Coast gonna get WET..
I saw a program on Discovery about it ...
The wave the huge mass of rock is going to make in the ocean gonna be making huge tsunamies....
The report states:
- 'La Palma has a very stable construction.'
- 'The island has an abundance of obstacles which would prevent any block from sliding quickly'
- 'Any block would break into pieces'
- They modelled the island, but 'whatever they tried they couldn't generate a significant tsunami'
- they even modelled the island higher and steeper but still couldn't get La Palma to slide into the sea.
- 'the so-called steam-kettle effect was modelled, but simply blew some steam out through the top of the ridge but excerpted no lateral pressure. (Needed by Ward/Day/McGuire to kick-start the rock-slide)'
- 'they calculated that the lateral pressure needed to move half of La Palma would be the equivalent of 600 million jet-fighter engines'
- 'the island might possibly become unstable if the island grows taller, at the current rate that would take at least 10000 years'
- of the BBC Horizon programs claim that 'a huge massive block of rock is just waiting to slide into the sea' they accuse the researchers (Ward/Day/McGuire) of having 'a complete lack of insight into ground mechanics'
- even under the most extreme circumstances they could only create a wave 15cm to 100cm tall at the coast of America
- the Delft researchers join the chorus of scientists who state that Ward/Day/McGuire used an incorrect algorithm to calculate the size of the tsunami.

Speaking on Tuesday, Ricardo Melchior, president of the island government, the Cabildo, was critical of Alicia García from the CSIC Higher Council for Scientific Investigation for speaking of concerns amongst scientists of the situation on Tenerife; he noted that another scientist from the CSIC, Juan Carracedo, says there is no risk, and added that the discrepancy between their opinions is proof of the need for a Volcanic Institute on the Canary Islands.
The island of Tenerife itself is the third largest volcanic ocean island on Earth by volume. Teide is also the third highest volcano on a volcanic ocean island. It is also unstable and possibly in a more advanced stage of deformation and failure than the much publicised Cumbre Vieja.
The large triangular island of Tenerife is composed of a complex of overlapping Miocene-to-Quaternary stratovolcanoes that have remained active into historical time. The NE-trending Cordillera Dorsal volcanic massif joins the Las Cañadas volcano on the SW side of Tenerife with older volcanoes, creating the largest volcanic complex of the Canary Islands.
We analyze the role of low-strength materials in the potential structural instability related to volcano spreading at the active Teide stratovolcano (Tenerife, Canary Islands). To study the low-strength materials we took advantage of a network of large tunnels within the volcano, excavated for water supply, which allows the in situ inspection and reconstruction of both volcano and substratum structure. We identified two factors which are potentially important to Teide's instability: 1) a dipping low-strength substratum breccia layer; and 2) a hydrothermally-altered weak core inside the volcano. Despite we do not find clear structural evidence for volcano substratum spreading, both Teide topographic shape and the summit faulting are features similar to those accepted as examples of volcano flank spreading over a weak core. The detected asymmetric deformation of the edifice makes the north flank of Teide a strong candidate for a potential failure.
