Earthquakes happen when two large pieces of the Earth's outside layer suddenly start shaking and that causes them to either bump into each other, slide past each other, or move apart from each other.
Are you wondering what an earthquake is?
Earthquakes can be big or small. In some small earthquakes, you can't even feel the shaking, but in big earthquakes, sometimes buildings shake and fall down and roads start to crack.
If you are ever trapped in an earthquake, don't worry. Here are some steps you can follow so that you stay safe.
If you are indoors, STAY INSIDE! Drop to the ground and take cover under a sturdy table or bed, but make sure to stay clear of windows, fireplaces and heavy furniture.
If you are outdoors find an open space and stay away from buildings, street lights and power lines.
If you are in a moving vehicle, you should stop, but carefully. Try and stay away from traffic and DO NOT stop under a bridge or any trees. When the shaking stops, make sure to stay away from fallen rocks, bumps and any cracks in the road.
