[Errant]

Thanks, saving to my library!

From the article:

The key characteristics of debris avalanches include a relatively narrow headwall and chute above 3000 m water depth on the island flanks...

I believe this applies to all the islands. If you removed the water from around El Hierro and stood on the highest peak, you'd be over 10,000' above the surrounding terrain.

Image from the site above that gives an idea of the island's underwater slope.

exactly...people are concentrating on above surface thinking that El Hierro being already deflanked(LOL) could not create a tsunami because well there's not much left to it, but in reality there is above and below but more importantly it's history suggests that it's more than prone to collapse.

Secondly I remain severely troubled by the continuous harmonic tremor...if anything beside a full scale eruption that will weaken the earth it would be the non-stop tremor.
