"Aftershocks have greater impacts than initial earthquakes". How far do you agree with the statement? explain.
AVprozaik [17]
Not at all. Aftershocks are much weaker and have less energy than initial earthquakes due to the energy having been spent on the earthquake itself. However aftershocks are unpredictable and don't always happen, so they could possibly do more damage, but they do not have greater impacts than initial earthquakes.

My opinion.
