When an earthquake occurs, computers create maps that show where the different strengths of shaking

When an earthquake occurs, computers create maps that show where the different strengths of shaking are likely to be. What factors are taken into account by the computer models to create these maps?

Can somebody help me answer this question?

thanks

1. soil type and thickness.

2. rock type.

3. depth to water.

Im not an expert but i have done a geography degree. I would imagine the strength of the shaking is likely to be calculated by how close you are to the epicentre, i.e. the location of the earthquake. The strength of shaking should decrease from this point outwards. Another thing that may be a factor is the type of rock that is underneath the ground. Seismic waves travel at different speeds depending on the substance they are travelling through. For example, a seismic wave will travel much faster through liquid than it will through solid rock and the density of the rocks will also make a difference. I hope this helps.
