WHAT WE HAVE IS A SUBMARINE VOLCANO GOING OFF THROUGH LA PALMA - I CALL IT!

pin me

Okay what’s the difference?

, submarine volcanic eruptions lead to large and sudden displacement of water or slope failure

Submarine volcanoes are not found everywhere under the sea, but only in places where magma rises close to the ocean floor. Most submarine volcanoes are directly connected with the movements of the Earth's tectonic plates . The outer crust of the Earth is covered with rigid plates that gradually move over the partially molten interior.

There are three circumstances where tectonic plates can interact with each other and the Earth's molten interior to form submarine volcanoes. One form of interaction occurs when a tectonic plate slides over a "hot spot" of magma under the seafloor. A second circumstance occurs where tectonic plates are spreading apart at the mid-ocean ridges, allowing magma to rise from deep within the Earth. A third type is where plates are moving toward each other, which often forces one plate under the other, in a process called subduction.




n certain areas of the ocean, hot magma chambers lie below the moving tectonic plates. Cracks and fissures penetrate into the magma chamber, allowing pressure to be released and magma to flow out onto the seafloor. Over time, underwater mountains, called seamounts, develop, and in some cases they may reach the surface of the ocean or above, creating volcanic islands. The tectonic plates are continually moving, but the magma chamber remains stationary. Eventually, the magma breaks through the ocean floor in a new location and another seamount begins to form.

Over geologic time, many volcanic seamounts may form in a row as the tectonic plate continues its advancement. This can create an underwater mountain range. If the volcanoes rise above the ocean's surface, they will form a chain of islands.


Subduction earthquakes can be the most dangerous to human life because they are often located along coastlines. Exploding mountains and lava flows are not the only danger from a subduction volcano. Earthquakes are always associated with submarine volcanoes and are usually small and numerous. Most of them are too small to be detected by seismometers on land.





AND THEN LOOOK



Researchers use underwater microphones, called hydrophones, to detect submarine earthquakes. However, earthquakes associated with a subduction zone can be quite large. As the ocean floor subducts, the leading edge of the overriding plate gets pulled along under itself. Eventually the pressure releases and the overriding plate snaps back up. This causes fractures that can produce volcanoes as well as significant earthquakes of magnitude 9.0 or higher. The land movement, in turn, can trigger massive tsunamis with the capability of widespread devastation along populated coastlines.

BINGO HERE IS WHATS ABOUT TO HAPPENNNNNNN

im wondering too
i mean the island literally is the tip of the vulcano.
it exists because of the vulcano. it is the vulcano

Uhm, I think this well known. That's how the islands there were formed.

I still suspect that La Palma will "Krakatoa" in a massive explosion and the entire island will disappear.

Yes it's the logical way to do it, as everything they do on the ground is too visible. Nuke it from a sub makes better sense.

Luk 21:25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;

can i haz a nice picture too?

You auditioning for one of those "Captain Obvious" commercials? The entire Canary island chain was created by underwater volcanoes.

Are you living in FLA/East Coast?

This is for you;

Could happen, the 1883 Krakatoa explosion is surmised to have happened because the magma chamber failed and let ocean water rush in causing a giant steam explosion that destroyed most of the island and caused a huge tsunami. It is reported that people in Perth, Australia could hear the explosion, 1,900 miles away.

doesnt work

Works here for me, but here's the link to u-tube for you; [link to youtu.be (secure)]

TWO MORE WEEKS!!!

That's why i am confused with what she is trying to say here, too, like you stated it so simply clearly. Thank you

THAT MAKES THE MOST SENSE. That area is mobbed with underground volcanoes.

Explosion and collapse.

Get Bushcraft Bear outtie first please, he is a treasure.

you should become glp's geologist!!
