What Causes a Volcano to Erupt A buildup of pressure and less dense magma on the bottom can cause an explosive eruption. An eruption from a volcano can also be because of an earthquake that shakes the volcano and makes it unstable. An explosive eruption will cause rocks and ash to fall from the sky. An eruption can be caused from the cone of the volcano to fall in on itself making the lava come out of the volcano in a river like a stream. An earthquake can cause a volcano to erupt from the tectonic plates rising up and pushing out the lava. …show more content…
Vesuvius erupted and covered the entire city of Pompeii in ash and Herculaneum in a mudslide. The only reason that we know what happened is because of pliny the younger and pliny the elder's writings. When the volcano erupted people started to hide in their house, and some of them ran away. Their was about 13,000 people killed between the 2 cities. The citizen that stayed in their houses were going to try to wait the eruption out, but they died from breathing in sulfuric gases. in Herculaneum everyone died from a mudslide from when the volcano erupted and covering the entire town in mud and ash.
My Reaction to the Eruption of 79 AD
My reaction too Vesuvius erupting was that how did most people die the day after. Why did people stay after the volcano erupted, to wait it out, I don't think that you could wait out a volcanic eruption and survive how did almost everyone die curled up in a ball and inside their houses. How did a layer of ash survive people walking on it and not crumple under the pressure. Why couldn't people use common sense and run away from the thing that that's spewing out ash and flaming rocks, grab what you need and run. I can see that everybody in Herculaneum died because you can outrun a mudslide made of ash and mud, but you could try.
Conclusion In conclusion, Pompeii and Herculaneum were buried under ash and mud/dirt for thousands of years until they were rediscovered in the 1700’s. Now they have what is supposed to look like Pompeii before the volcano
