Volcano, Magma, Earth What If We Poured Concrete Into a Volcano?

Fire and destruction are all around you.. If only there were a simple trick to stop an eruption. Like maybe plugging up those magma mountains with good old concrete. Concrete, is the most used material in the world.. With 18 billion metric tonnes, 20 billion tons used every year you encounter it everywhere.. Even the Colosseum was constructed using concrete. That was nearly 2000 years ago and its still around today.. This incredible, durable material is made of gravel water and a bit of cement., And it only gets stronger with time.. The strongest of concretes can withstand the pressure of Challenger Deep, the deepest part of our oceans., But would it withstand an erupting volcano Or would it be like extra deadly Mentos and Coca Cola? Volcanic eruptions involve a lot of heat and pressure.. If we poured concrete into a hot volcanic mouth, surely it would just melt right? Well, not exactly.. Concrete has a melting point of about 1500 C 2700 F. Even the hottest orange lava only reaches 871C 1600 F., But just because it wouldnt melt doesnt mean it could work. Volcanoes erupt. When the internal pressure from the magma reaches the point where the ground covering it breaks, apart., Eventually it collapses and the magma runs free. The greater the pressure difference between the surface and the magma, the more explosive the volcanic eruption. So putting a concrete plug on a Volcano would be a dangerous addition.. We would be forcing the pressure to build up below the ground.

Much higher than it usually would.. This would make the inevitable explosion even more energetic.. If the magma were unable to penetrate the concrete it would explode out of the volcano. Sides., This is a Vulcanian eruption.. This happened in 1980 when Mount St. Helens erupted.. The pressure build up was so massive that one of the sides was bulging out into a dome.. The pressure became so great that the dome broke and the volcano erupted. Sideways. This powerful explosion ejected material at a velocity of 350, ms 1150 fts. Dozens of people died. Our concrete strategy, wouldnt only end up with a Vulcanian eruption.. The concrete plug would burst out too.. The dust from the concrete would lead to fatal lung diseases and cancer.. The lava flow from a natural eruption is usually slow and predictable., So maybe a better plan would be to use the concrete to divert the flow away from cities and towns. Like in 1983, when Mount Etna erupted in Italy.. The lava flow threatened, three towns. Barriers of rock and ash were created to divert it.. The first barrier stood at 18 m 59 ft and it was quickly overrun.. The second barrier kept the lava from traveling further west., So we could use concrete to form barriers or walls to protect towns and cities.. But you probably shouldnt throw a ton of concrete bricks into the flow to see what happens. You might be better off, trying something colder. Like an iceberg. But thats a story for another.
