Earthquake structures

In Owls we have been studying all about earthquakes. We have learnt that there are 2 scales used for measuring the intensity of earthquakes. The first is called the Richter scale which is recorded on a seismograph and the second is called the Mercalli scale.

We had a go at creating a structure that would withstand an 'earthquake' and discovered lots about the materials and shapes of structures that should be used to make a building more earthquake-proof. Below is some photos of us creating our structures.

What's the difference between the Richter and Mercalli scales?

What shapes are better suited to earthquake proof buildings?
