T'owd volcano shows no signs of stopping ....

Still very impressive and dangerous.

 

I watched a Tv programme about 10 years ago. There is a volcano on the canaries, forget which one, they reckon if it blows its side off (which apparently is a distinct possibility) it could trigger a Tsunami that would drown the eastern US seaboard including New York in a 100 meter high wave

 

Tenerife

 

Other activity yesterday in Alaska and Hawaii.

 

And incredible noise!

 

Are you sure you weren't watching a disaster film? There is no chance of a 100m wave hitting New York as a result of an eruption in the Canaries.

 

Apparently some seismologists do think it is a possibility and the volcano is highly unstable...

 

No he's right.
It is a known fact that if the side of the mountain, in La Palma I believe, were to split and fall into the Atlantic then the ripple effect across the ocean would exponentially grow and the East coast of the USA would be very seriously inundated.
It is a fact, not make believe !

I've done a bit of googling and the above talks about La Palma and tsunamis.

Teide is due an eruption by the sounds of it and is one of the highest volcanoes in the world.

I'm sure the chances are minimal but possible.

 

Now that would be something !
Something unimaginable and disastrous.

 

Scientists are in agreement on this, its not if but when. The only caveat is that it will take a major eruption or quake to trigger the worst case scenario.

 

I'm not doubting there could be a tsunami, but a wave 100m high? Surely not.

 

Have a read about mega tsunamis on wiki. There's been quite a few over 100m. Some way higher than that. One in Alaska in the 50s that was over 500m high!

 

Depending upon the amount of water displaced 100 metres is worst case.
However they reckon 20-50 metres could be expected in certain parts of the East Coast. Florida and the Carolina's would be in serious danger of the waves. They also state the waves would reach quite far inland, making an evacuation really challenging. Can't remember how long the wave would take to travel, but from memory the wave would travel at around 500 mph.

 

Just read this. Seems we're alright after all!

 

Washington state waves were 125 metres, they created a whole new coast line and wiped away cliffs.

 

I was under the impression it was Teneriffe but seems I have confused it with historical research

That saying, it is still feared both La Palma and Teneriffe can cause further massive tsunamis

 

Gosh. I started something there. Knew it was a documentary, not a big fan of disaster movies, we generate enough real situations without having to invent them. I seem to recall that the height of the wave is debatable but is largely predicated on the slope of the sea bed before land fall. The longer and shallower the slope the greater the speed and height of the wave. Just shows one thing. For all we think we are masters of the universe, nature is something we can't fathom. A bit like schopps tactics then

 

There's one in Hawaii that would do the same to the US Pacific coast and most of Aisia.

 

I visited La Palma a few years ago and we were given a guided tour of the main volcanics, including the amazing Taburiente volcano and the site of the last eruption in 1971. A lot of the BBC findings were rejected by the vulcanologist who took us round who said that it would be a hugely unlikely event that half the island would collapse into the Atlantic as stated in the programme. If you stand at the peak of the crater of Taburiente, you can look straight down the line of volcanoes which have erupted along the line of the tear fault between the African and Atlantic tectonic plates. The BBC programme seemed to suggest that a significant issue might be the boiling of water trapped between vertical barriers formed by volcanic dykes, which would be explosive in a major eruption, but very unlikely to happen. This has not been an explosive eruption, but it has been a prolonged one, so at least this volcano is letting off lava gradually and predictably and without threat that that a much more explosive event is building up. The Canary Island tourist board don't advertise the fact that most Canarian volcanoes are not extinct, but rather dormant. A new island appeared in the sea off El Hierro only five, or six years ago. El Teidi last erupted sometime around 1911 (the ash cone at the top - but dates seem to vary). You can cook meat at the vent of Timanfaya on Lanzarote. The Canarian volcanoes are anything but extinct, but at least they are not the major threat of a Mount St. Helens.
