East Coast Alert: 602 Earthquakes on La Palma - Could Cause TSUNAMI Wipe-out of Entire US East Coast

[pyrangello]

There sure are many volcanoes becoming active lately, and many of here at avalon have been reporting on this island for years, it gets active then settles down. This is probably the most active in years, doesn't show up on the earthquake charts though. Just something to pay attention too, theres nothing we can do if this goes except pray at that point.

A little more context here. Yes, it's a potential problem. The issue is that there's an island in the Atlantic called El Hierro ("The Iron") which has a huge detached rock sitting there that's 500 km3 in volume, 25 km long, 15 km wide, and 1400 m thick.

That's a big rock! :) A quick estimate suggests it weighs about three trillion tons, enough to create quite some tsunami if it was dislodged by a major earthquake and slid into the Atlantic.

Here's a PDF which contains a bunch of calculations and interesting images:

... yeah... yeah...

Hervé, somewhere in the El Hierro thread explains the whole model to be flawed simply because the hypothetical landslide - even if huge - is punctual hence the energy gets dissipated quickly as the wave's perimeter goes larger and larger as it does when throwing a rock in a pond. Still dangerous for Canary Islands inhabitants, though.

La Palma is indeed a very large stratovolcano. Her last major eruptions was in 1971 and it was very fast to build dikes and shoot out bombs of pyroclastic material. In October there was another swarm of earthquakes recorded. She is definitely waking up but eruptions like this occur over a long period of time, that being said we also know that huge eruptions, while rare, do happen. Think of Mt. St. Helens. It could happen, it could happen tomorrow but you cannot live in fear of it happening! We could also get hit by another asteroid like the one at the end of the Cretaceous period that wiped out most living things (Chicxulub). Or...the San Andreas fault system could slip...or the Ring of Fire could become very active. One thing you can be sure of, the Earths crust will always remain in equilibrium (isostacy) so when an amount of mass is removed from one spot it will basically be balanced out somewhere else.

Is the new earthquake swarm beneath La Cumbre Vieja volcano in La Palma, Canary Islands a sign of the upcoming mega-tsunami ?

On a side note , if we weren't having any volcanoes blowing off I wouldn't even pay attention to this but things are pretty active now. The earth is always moving and shaking. Am I going to loose any sleep over this? No . Thats the beauty of the Avalon family, explanations eliminate fear, so forward we go everyday :).

I have trouble with this article that compares the Hawaiian volcanoes (shield volcanos) to the La Palma volcano (stratovolcano). The geologic processes behind them are very different. After pondering the La Palma tsunami I have questions I would love to ask them about their model....did they account for seafloor changes would be a big question. Any wave of this size...assuming a bunch of variables....if it made it to the East coast it would break far before it reached shore. Waves break when they reach a shallow coastline where the water is half as deep as the wave is tall.

... again, Hervé, somewhere, speculated that the only way to generate a lengthy linear wave of such amplitude and height, would be if an obduction/subduction suddenly occurred along the US East Coast and even worse, simultaneously along the west African coast...

Now, the above WAS something intended to happen via some control demolition scheme involving thermonuclear deep charges placed along these coast lines to simulate such "natural" tectonic phenomena.

According to Kim Guogen, these nuclear devices were "demolecularized" very recently (same as with the Chinese Fleet stationed around the US) so that, unfortunately, wnlight never received that memo (https://projectavalon.net/forum4/showthread.php?102695-World-Wide-City-Population-Changes-by-End-of-2019&p=1381967&viewfull=1#post1381967) before he passed away.
