And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Satellite images of the Cumbre Vieja eruption on the island La Palma, in the Canary Islands. Plus, a new vent has just opened up, suggesting more pressure from below. Stay tuned...
As I understand it, the big danger here is a large part of the volcano slumping or blowing out into the Atlantic causing a tsunami to cross the ocean hitting the U.S. East coast some 50-100 feet high. Scientists have been worrying about this specific issue with this specific volcano for years. Haven't heard anything in our MSM about this. Have you?
As I understand it....this volcano wouldn't do it. It would have to be a large portion of the western half of the island sluffing-off into the sea in a much larger event.
If I recall correctly, a geologist wrote a paper postulating this about 20 years ago and it sent everyone in the Caribbean into a tizzie (I was working there at the time). La Palma is a volcanic seamount and the ocean around it is deep, plus the island has a large structural fault running down the middle. So if a large portion of the island were to slip along the fault line, it would have a long way to slide downhill (underwater), hence the tsunami risk. But I think in this case science did what it was supposed to do: It got other geologists looking into it and I think the upshot was, yes there is a fault, but the catastrophic danger levels are pretty low when the expected energy of the eruptions here are taken into account. I think it's generally accepted that the initial assessment of the danger was too high.
There are a lot of volcanoes popping off these days, CW. Don't come to me for answers. Life imitates art, even on the Canary Islands. Do they still have canary birds there?

ReplyDeleteThe Canary Islands are named after dogs (canids), not birds. If there are any canaries there, they were brought by the settlers.
