This is question 2

Hey! Vanessa W. posting!

This is my part of my project.

Its is about how to predict volcano eruptions.

Here are some information:

- Scientist use a seismometer to sense and detect the intensity of earthquakes caused by magma that is moving. This is one way of telling if the magma is going to rush out of the volcano. There are earthquakes because the magma stored in the mantle is too much and tries to escape out. when the magma moves, it will not move straight so it might spread to the other parts of the mantle when it is rising. As the mantle supposed to be solid, when the magma spreads it causes the mantle to crack and thus cause a small earth quake to happen

There are four different kinds of seismograms. They measure the strength of the movement of the earth at different levels in the Earth's crust.

Here is a video to explain

That was a scientific way to look for a volcanic eruption.

People who are not scientist like us can look out also.

-We can look for plumes of smoke or clouds of gas or around the volcano that were not there typically. As the magma flows into the chamber beneath a volcano and rises, it will cause different gases to be released.

Example of gas: water vapor (H₂O), carbon dioxide (CO₂) and sulfur dioxide (SO₂)

We can also look out for seismic activity near the volcano. Many volcanoes countiuously give off rumbles or tremors brfore they erupt.

Look out for buldges, cracks and increase slope shapes in the ground are also indicators of a volcanic eruption as when there are tremors on the earth ground, these land formations start to change.

here are two other videos to add on to how to predict.
