Worries of a potential volcanic eruption have prompted Spanish authorities to evacuate residents and tourists on one of the Canary Islands. Thousands of tiny tremors have recently intensified, with the biggest one reaching a magnitude of 3.4, they said. The seismic activity indicates magma on the move. Info
Thousands of tiny earthquakes have rattled the island of El Hierro since this July. But recently the tremors have grown stronger, prompting concern from officials, who fear that a volcano on El Hierro, one of the Canary Islands, could be about to erupt.
On Wednesday, more than 50 residents and tourists staying at the base of the volcano were evacuated, and 11,000 locals nearby were advised to stock up on water, medicine and flashlights in case of an emergency.
Some 8,000 tremors have been registered on the island since July 19, according to the Spanish National Geographic Institute (IGN). Though most of the quakes occurred at sea and were too minor to be felt, they have been increasing in intensity, with one reaching a magnitude of 3.4 on the Richter scale early on Wednesday morning.

See 38. You are wrong in general, and also wrong in particular to believe that “The remaining part of La Palma will block some of the wave, limiting the effect on Europe.” Tsunami waves are not “blocked” by islands, they are encircled by the wave energy which simply wraps around them.
There is so much ignorance of physics and hysterical misinformation on these stories I want to just hit my head on my keyboard.
The bike isn’t a bad idea. There are few Eastern metropolises that could be evacuated in any reasonable time. It recently occurred to me the sensibility of knowing the nearest significant elevation at all time; It wouldn’t take that big of a wave to sweep all the way across Florida, amazingly enough; you can go clear from mid-state Atlantic coast to Gulf coast without getting higher than 20’.
Yeah! There is another freeper who understands high school physics! (See 38).
Please see my 38, and the post by lonesome in Mass a bit after 38.
Please, set this worry aside.
(IIRC) the Science Channel ('09).....
,had a special about that very possibility
the Carolinas / Georgia were hardest hit.
Why worry about Florida? The entire East coast up the the height of the wave - what ever that height turns out to be - will be obliterated - in the sense that everything will be scowered down to bedrock.
See Lituya Bay, Alaska for what the damage will look like. Two video included.
You can't surf your way outta this one.
"Ship me 20 cases of Jumbo Prongs".
Please see 38, and don’t be hysterical. Comparing the 360* spread of a single point event in the open ocean to the channelized and focused energy in a BAY in Alaska is just plain foolish.
Now, if you could first build a giant “Grand Canyon” across the Atlantic, keeping all of the wave energy in that channel and aimed at Florida, then I’d agree we have a problem.
But I don’t see a “Grand Canyon” being created with walls higher than the surface of the Atlantic anytime soon.
Folks: Energy dissipates rapidly when it spreads out over 360* and thousands of miles! See 39 for a few basic numbers.
Good points; any thoughts on whether or not there would be any particularly nasty effects from that part of the wave that gets trapped inside the Gulf of Mexico, or any portions that would reflect off of the northern sides of South Africa and, perhaps via Cuba, end up trapped in the Gulf as well?
NO big deal..most of Florida real estate is already well “under water..” (g)
IIRC, on La Palma, there are THREE volcanos along the central spine of the island..at one time, when the Canaries were formed, it must have been a “hot spot” in the earth’s mantle, similar to how the Hawaiian Island were formed, ( and indeed, a new one is being formed now). Two are extinct ( or believed to be..but the entire mountain range consists of somewhat porous rock..over eons, water works its way in..so the effects of one erupton could cuase the entire west side of the island to slide into the ocean..
It’s still just a single-point energy release. Doesn’t matter if it’s caused by an H-bomb, or a landslide. Doesn’t matter if the ground pushes up from below, or falls down from above. The 360* spreading energy formula is what counts. Since energy is conserved, it RAPIDLY loses its wave height as the circumference grows geometrically.
The Christmas tsunami was NOT a single-point-origin event, but was 100s of miles long. As a result, the 360* energy dissipation was not in effect. The “shoulders” of wave energy on each side of any point along the tsunami reinforce the wave, preventing it from spreading out in 360* and losing its energy.
I really don’t see what is difficult to grasp here.
I don’t think it would have major effects across the Atlantic. The energy by then would just be too spread out. Locally in the Canaries, and even in West Africa, it might be pretty dramatic.
Oh, brother, I give up. Adios, all.
They are wrong.
La Palma will not slide into the sea.
Even if it did, it wouldn't cause a tsunami that would reach the USA

OH, yeah?! well you know man like my bro in law is like this major electrical wizard and hes a gor real dood and said that like you know that volcano could create an electrical discharge thing you know and create an EMP blast that also wipes out like the total CONUS and my AO would be FUBAR fer sur and i think yor just a doodo head
Good time to get that cruise on sale I would think.
“Come see the volcano! Only an extra $500!”
hehe. I guess it is all in how you sell it.
