people wont survive
the temeperature will drop
the lava will wipe out everything for 100 km around the volcano
50 cm of ash will fall in an hour
the dust and gas will block out the sun for a long time
plants and animals will die
Inevitably, the Yellowstone caldera will explode as a supervolcano. Whether that will happen soon is unlikely.
Yellowstone is the site of a very large volcano that is often referred to as a supervolcano. Much of what it erupts is rhyolite.
Along subduction zones or boundaries. Or places with a active volcano near them because sometimes when a volcano erupts, or when it almost erupts, the pressure underground could release an earthquake.
yes,they do.
it will explode
it turns into steam
Yes. In fact, Yellowstone National Park is a supervolcano.
A caldera forms when a supervolcano undergoes a massive eruption, causing the empty magma chamber beneath the volcano to collapse, creating a large bowl-shaped depression. This collapse can be triggered by the release of enormous amounts of magma and volcanic gases during the eruption, leading to a sudden decrease in pressure that causes the chamber roof to fall in.
One can find information about a supervolcano at Wikipedia, various websites where geologists and volcano enthusiasts gather and discuss information about supervolcano.
All the water falls back down to the ground.
They both blow steam
Scientists have no idea what the precursors (or warning signs) are of an impending supervolcanic eruption, and thus have no idea when the next supervolcano will erupt. The last two supermassive eruptions (Taupo and Tambora) occurred long, long ago (24000 and 72000 years ago), and we have no knowledge of what happened leading up to the eruptions (such as increased earthquake activity or patterns). The last three eruptions of the Yellowstone supervolcano have occurred at roughly 600,000-700,000 year intervals, and the last one took place ~640,000 years ago. It could happen soon, or not for tens of thousands of years or more.
