Volcanic Eruptions, & Lava Flows

[Tylosaurus]

Hey all

For about 5 hours I been watching documentaries about Volcanic activity current and past, but this particular one actually got my utmost attention on what to expect from a large scale explosive eruption, like the one that took place on May 26, 1883;
This documentary explains what causes the Krakatoa to literally explode, the happening of two sorts of Magma mixing...

Krakatoa by Naked Science narrated by John Shrapnel

This documentary that was made and narrated by Jerry Magloughlin explains the varied lava flow types that can take place in Hawaii and what causes them to occur

After watching these two and a bunch of others, they do kind of help you understand what actually goes on within the Volcano it's self before and during the eruptions.
I was impressed on how far science has improved over the many years to accurately calculate and predict an eruption's event on when it takes place.

Then comes the Yellowstone Super Volcano, if that things erupts, I wonder if the entire earth will be affected by it even 5 years after it.
I am hoping to find more information on Volcanic activity here,t hey always have inspired me tbh

[Insert entity of personal preference here] save us all when this happens,... then again, evolution will take sound care of life's seed whatever happens, so I guess it could be the better for the world as a whole if not for us. In any case, I'd like to be witness (but most likely won't be).

Thanks for sharing links. Also, for some decent in depth information on volcanic activity, plate tectonics and geology in general I recommend Stephen Marshak's "Essentials of Geology". Got some years on its back, but still seems to be a principle source for students of geology.

Life will find away...but yeah, I don't want to be present when Yellowstone blows up.

Hmm interesting thanks for the tip of Essentials of Geology Lanthanotus, I'll look in to that
A few years back in walked  on the crater's edge of the Vesuvius, in Italy.
A few plumes of hot steam & gasses were still extracting from certain vents or cracks from it's crater walls.
The Italian Vesuvius guides say that it's asleep for now and that it's all a matter of time before she erupts again.

Here some pics of the book I have of the Vesuvius Volcano that I bought at the time I was there

Rear cover:


Three diagrams showing the thickness of material that was ejected during three different eruptions back in 2000BC, 79 AD & 472 AD and a a water fountain from Pompeii on the right page:


The main crater, the little building in the center is where I bought this book


Left photo shows the ultra wide area that was once filled with down steaming lava rivers besides the Vesuvius Volcano on the right side of this shot, as where Mount Somma opposite of that

The right page shows the steep winding road that leads to the crater of the Volcano it's self, my parents and I drive up there with out guide in a Fiat Panda 4x4

Here some prehistoric cones vents and remains of varied Lava formations, such as the roping effect we see on the right page:


Here some art pieces of two different eruptions of the Vesuvius Volcano left the one from 1794 and the right from 1872:

Both of these can be seen at the Saint Martino Museum in Italy.
