On Io, the floor is basically lava.
Shaped by erosion, fire, or water, caves have some surprising but always beautiful births.
There’s no need to panic though.
Volcanoes are some of the most amazing geological features but quite often, they’re misunderstood or not understood at all. Here we’ll get to know them a bit better, starting with the basic facts and the moving onto cool and surprising facts, and of course, continuing with everyone’s favorite (from a distance): eruptions. Basic Volcano Facts 1. Volcanoes are ruptures in the Earth’s crust.
Even as a geologist, I can’t help myself from looking at lava with an almost childish fascination – it’s something from the depths of the Earth (literally), with the potential to destroy everything and anything in its path, and also to create new landscapes, drastically changing the surface of the Earth. In the short film above, Lance Page managed to capture the sheer force
Lava is amazing to see (from a distance), but it’s even more awesome to get the chance to see lava going directly into the ocean. Hawaii is one of the few places in the world where this happens. In this amazing footage, Kawika Singson uses his GoPro (hopefully on a very long pole) to get up close and personal with lava spilling into the ocean water. The video was captured off the coast of Hawaii.
The general classification splits volcanic eruptions in two: explosive or effusive. An explosive eruption is, well, explosive and violent (think Mount Helens), while an effusive eruption is associated with lava flows (think Hawaii). However, in a new study conducted by New Zealand and UK researchers described another, new type of eruption. Inside volcanoes, magma often has dissolved gases as a
It wasn’t just a devastating asteroid that killed off all the dinosaurs 65 million years ago. Scientists from Boston University now claim that a massive eruption of lava fronts around the world, coinciding with the asteroid impact, sealed their fate forever. The controversial theory is betting on two unusually hot blobs of mantle 1,700 miles beneath the crust that formed
Eyjafjallajökull (how ever you pronounce) is a volcano located in Iceland, covered by a small glacier with the same name. It’s crater has a diameter of about 3-4 kilometers, and it erupted the second time this month, causing a cloud of ash that forced authorities to stop almost all flights above Iceland. The problem, when you have such a volcano,
Scientists have for the first time determined the actual permeability of the asthenosphere in Earth’s upper mantle, which is basically responsible for how fast the melt rises towards the surface of the earth, and the results were surprising to say the least. Researchers found that it actually moves 25 times faster than previously assumed, which forces us to reconsider every
