Submarine activity

I think I'm correct in saying the submarine activity is occuring directly in the path of the slide zone. Would that mean the tsunami would be deflected?

El Hierro 1 comment

How concerned should we be with regards to the eruption off El Hierro, and its effect on the fragile west coast of nearby Tenerife.

Hello!

Surely nobody knows when and if there will be an eruption on land or submarine. So we can not estimate if any activity of the El Hierro volcanoes will have an negative impact on Teneriffe. I think there is enough distance between the two islands. The only problem would be if there would be a land slide that runs into the sea or if the ash effusions would stop air traffic. But until now there is no real danger.

Possible eruption on El Hiero 2 comments

If there is an eruption in the Canary Islands, will it produce waves or a tsunami on the Costas of Spain? There are no warning systems here so how would the population of Marbella, for instance, know that it's time to get to higher ground. There's nothing on the local radio about this. Gives me the shivers.

If El Hierro has a cataclysmic eruption and splits in two I'd be very worried. El Golfo bay is an indication of just how powerful an eruption can be. Spain, Africa and East Coast of US is very vulnerable to significant damage.

Hello!

The not-existence of Tsunami warning systems is a general problem in Europe. Especially in the most dangerous areas where Tsunamis happened in historic times (Greece, Italy, Spain and even around the Northsea).
... plus

Not only El Hierro could cause a Tsunami (what I do not belive to happen soon), but there are many areas with deep faultsystems, volcanoes and loose sedimentary rocks on coastal areas.

Generally human being doesn´t respect nature and only if a disaster happens, the politics "wake up".
