Rudolf-earthquakes

Earthquakes are created when the plates move sideways, and pieces of the plate get caught by the other plate. Then energy builds up, and when the energy is released, it creates a earthquake.

The strength of an earthquake is measured with the Richter's Scale. Every number in the Richters scale is ten times stronger then the previous one, meaning that if something measures 7 on the Richters scale, it is one million times stronger then something that measures 1 on the Richters Scale. The strongest earthquake ever recorded happened in Chile, South America, 1960, and measured 9.5 on the Richter's Scale.
