Question
For an earthquake of magnitude M = 7.0 and depth 25 km, calculate the peak ground
acceleration at a site 50 km from the epicentre using the attenuation relationships for
Europe, Japan and western North America (randomly oriented horizontal components).
The fault mechanism is normal and the seismic waves travel through a thick layer of rock
(v =780 m/s). Compare the results with the prediction of the worldwide attenuation rela-
tionship. Plot the curve of the above attenuation relationships for M = 7.0 and comment
on the plots.
