Red Alert: Volcanoes

Volcanoes can be fun to learn about. It can be neat to watch them erupt. But if you live near a volcano, you know that they are dangerous! An eruption can like an explosion. Rock and lava can throw up into the air. Streams of red hot lava quickly run down from the peak of the volcano. The air is filled with deadly gases. These things can put many lives in danger. Scientists have learned that there are many things that they can study to help them tell when an eruption might happen. They can study the movements of the ground. When a volcano is about to erupt, the ground will often move just like it does during an earthquake. Scientists can also measure the gases that come out of a volcano. Most volcanoes emit gases all of the time. More gases are let out as the volcano gets closer to erupting. They can also study the way the land and water around the volcano. Scientists can read these signs and warn people of danger. They may not realize it, but their work helps to keep people safe!

Read the following passage, and answer the questions that follow

On April 30, 2018 the Pu’u ‘O’o crater on Hawaii’s Kilauea volcano, suddenly collapsed. It was the starting point for the volcano’s months long eruption, which went on to produce 320,000 Olympic-sized swimming pools’ worth of lava that transformed the landscape and ultimately destroyed 700 homes.

A volcanic eruption occurs when hot materials from the Earth's interior are thrown out of a volcano. Some eruptions are terrible explosions that throw out huge amounts of rock and volcanic ash and can kill many people. Some are quiet outflows of hot lava. Several more complex types of volcanic eruptions have been described by volcanologists. These are often named after famous volcanoes where that type of eruption has been seen. Some volcanoes may show only one type of eruption during a period of activity, while others may show a range of types in a series.

When does a volcanic eruption occur?
