Scientists believe they've discovered the largest volcano on Earth! But it's not the biggest one out there. Trace looks at the greatest volcanoes in our Solar System. Read More: Underwater volcano is Earth's biggest http://www.nature.com/news/underwater-volcano-is-earth-s-biggest-1.13680 "Geophysicists have discovered what they say is the largest single volcano on Earth, a 650-kilometre-wide beast the size of the British Isles lurking beneath the waters of the northwest Pacific Ocean." The Tallest Mountains in the Solar System http://blogs.smithsonianmag.com/science/2012/01/the-tallest-mountains-in-the-solar-system/ "If asked to name the tallest mountain on Earth, most people would answer Mount Everest. They'd be wrong--Everest is the highest peak on the planet, but mountains are measured from their base to their peak, and Everest's base sits far above sea level on the Tibetan Plateau. And when you start looking at the tallest (known) mountains in the solar system, Mount Everest, at only 2.3 to 2.9 miles tall (depending on where you decide the mountain's base is located), doesn't even make the list:" Io: Overview http://solarsystem.nasa.gov/planets/profile.cfm?Object=Jup_Io "Looking like a giant pizza covered with melted cheese and splotches of tomato and ripe olives, Io is the most volcanically active body in the solar system. Volcanic plumes rise 300 km (190 miles) above the surface, with material spewing out at nearly half the required escape velocity." Deep In The Pacific, Scientists Discover Biggest Volcano On Earth http://www.npr.org/blogs/thetwo-way/2013/09/06/219690370/deep-in-the-pacific-scientists-discover-biggest-volcano-on-earth "The world's largest volcano has until now been lurking undiscovered in the depths of the Pacific Ocean, according to a team of scientists who identified the massive object and reported their findings in the latest issue of Nature Geoscience." OLYMPUS MONS http://marsprogram.jpl.nasa.gov/gallery/atlas/olympus-mons.html "The largest of the volcanoes in the Tharsis Montesregion, as well as all known volcanoes in the solar system, is Olympus Mons." Olympus Mons: Giant Mountain of Mars http://www.space.com/20133-olympus-mons-giant-mountain-of-mars.html "Olympus Mons is the largest volcano in the solar system. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption." Plate tectonics confirmed on Mars http://io9.com/5933638/plate-tectonics-confirmed-on-mars "After nearly forty years of research, scientists have finally proven that plate tectonics exist on Mars. A recently published paper by An Yin in the journal Lithosophere reveals that the origin of Valles Marineris on Mars — the longest trough system in the solar system — was formed by rifting, strike-slip faulting, and subsurface mass removal. Yin's research now shows that Earth's surface is not the only one in the solar system subject to the forces of plate tectonics."

Huw James took a trek up Mount Etna and decided to show us what actually happens when a volcano erupts! With a little bit of help from Dr Suze Kundu and using a simple demonstration heating a glass beaker of wax, stone, sand and water we can see what happens when a volcano erupts. We can actually tell a lot about a volcano looking at the lava that comes out. If the lava is quite dense and thick we know it contains a lot of the compound silica. If it is less dense it has less silica and spreads out a lot more. Thick lava will generally erupt from one vent and follow one flow down the side of the volcano. Thinner lava, lava that is less dense, generally erupts from the surrounding magma chambers and flows in many different channels. Did you know that Mount Etna erupted recently? Check out this amazing video from BBC News! http://www.bbc.co.uk/news/world-europe-24980153 Have you found yourself half way up an active volcano and need to find north quickly? Well Check out Huw's vid on How to find North: http://www.youtube.com/watch?v=HalWPa6Ef5E&list=PLMrtJn-MOYmd9qywSe0JaCOed0t4CVV1l&index=3 Wonder why it's colder when you're high up a mountain?

Have you ever found yourself in the path of molten lava? Has the volcano you're climbing suddenly erupted and you don't know what to do? Well keep watching because Huw James has all you need to know. The earth is built on tectonic plates that move around on the mantle. Sometimes these plates move around and come together to form mountain chains like the Himalayas, some rub together and set off earthquakes, and some like Mount Etna, interact and one plate goes underneath the other. So here are our tips: Listen out for a rumble and keep an eye on tremors Keep a radio close so you can listen out for advance warnings Protect yourself from volcanic ash. It is very nasty stuff Do not get in your car as the ash will catch up with you, ruin your engine, and you will be stuck in the danger zone! Remember all those flights were cancelled when Eyjafjallajökull started erupting in 2010? Keep an emergency supply of water to stay hydrated And Good Luck! How Eyjafjallajokull unfolded: http://news.bbc.co.uk/1/hi/8634944.stm Did you know Mount Etna erupted recently and it started raining rocks! http://www.geekosystem.com/raining-rocks-sicily/ For more experiments on Mount Etna check out Huw's video on how to find north: http://www.youtube.com/watch?v=HalWPa6Ef5E&feature=c4-overview-vl&list=PLMrtJn-MOYmd9qywSe0JaCOed0t4CVV1l http://www.youtube.com/user/HeadsqueezeTV http://www.youtube.com/subscription_center?add_user=HeadsqueezeTV

Lightning is one of mother nature's most spectacular phenomena. But add lightning to a volcanic eruption and the event seems otherworldly!

Travel video about nature park Hawai'i Volcanoes Park in Hawaii. Located to the south east of Hawaii, the Hawaii Volcanoes National Park is the youngest island in the archipelago and the only one that contains active volcanoes. Its abundant vegetation and beautiful volcanic landscape attracts tourists,explorers and scientists from all over the world. To experience this paradise born of lava is to glimpse into the early beginnings of Planet Earth. The dry, dark-coloured side of the volcanoes, the Kau Desert, is almost lifeless. Lava stifles any form of plant life and the magnificent expanse of strange, dark scenery and huge, billowing clouds is a truly awe-inspiring spectacle that is like nowhere else on Earth. The park contains the world’s most active volcano, Kilauea and also its largest, Mauna Loa. For the Hawaiians, the environs of Halema`Uma`U, the “House of Fire,” and the crater itself, were once the most holy place in the entire archipelago and the tremendous dimensions of the crater and the clearly visible strata that have accumulated during many thousands of years, are particularly impressive. In spite of the lava, the humid north east of the island has created a jungle, while the southwest is rich in savannah, a visual symphony of mighty eucalyptus trees and plants up to eight metres tall that are framed by dark lava. Where once scorching volcanic streams flowed, today the sun beams down onto the benign, cooled down surface of the lava. When visiting the world’s most active volcano, Kilauea, it’s like witnessing Earth’s creation. When the blazing red lava sizzles into the sea and the water boils and the clouds glow, the might of the Earth is at its most extreme. Those who experience the raw beauty of this island will never forget the many unforgettable moments surrounded by a natural environment that has learned to constantly renew itself in dramatic style.
