We are learning about earthquakes because new fences have gone up at Russell School, at the ends of the buildings, where there are bricks.
This is to keep us safe if there was a big earthquake.
In a big earthquake the bricks could fall and hurt people.
The fences are there till they can take the bricks away and replace them with something safer.
We are also going to take part in the New Zealand Shake out so we will know what to do if there is a big earthquake.
We hope you will practice too, so you are safe.
