Question

What are some damages for aftershocks

Answer 1

The aftershock was responsible for additional damage and casualties, as well as for delaying efforts to free people already trapped beneath rubble. There are also examples of large aftershocks' causing more damage and loss of life than the earthquakes they are associated with.

Answer 2

Some consequences of aftershocks are further worsening structural damage already caused by the earthquake (which leads to further loss of property and lives), building collapses, and moving places that are along fault lines (California for example drifts northward a tiny bit each year).
