What is the distinction between primary and secondary impacts arising out of seismic events?

  • Primary impacts are those which cause the most damage whereas secondary impacts take longer to occur and generally have smaller impacts.

  • Primary impacts are those which appear immediately following the event, such as fires. Secondary impacts come about as a result of the aftershocks, such as bridge collapse.

  • Primary impacts are immediate and a direct result of the tremors. Secondary impacts arise in the aftermath and are a consequence of the primary impacts.

  • Primary impacts link directly to the P Waves and the type of tremor which they cause. Secondary impacts are directly connected to the type of tremors associated with S Waves.

Calculate the mean and interquartile range for the data set in Figure 6 and interpret your findings.

Upper space quartile space equals space fraction numerator 𝑛 space plus space 1 over denominator 4 end fraction

Lower space quartile space equals space fraction numerator 𝑛 space plus space 1 over denominator 4 end fraction space cross times space 3

Interquartile space range space equals space upper space quartile space minus space lower space quartile. space

𝑛 space equals space number space in space sample
