What is another word for aftershocks?
Pronunciation: [ˈaftəʃˌɒks] (IPA) 
Aftershocks are usually defined as a series of tremors or vibrations that occur after a major earthquake. Synonyms for aftershocks may include tremors, shocks, vibrations, quivers, shudders, or convulsions. These terms are used to describe the continuing seismic activity after the main earthquake has subsided. Other terms that are synonymous with aftershocks include secondary shocks, residual tremors, or post-earthquake tremors. Generally, aftershocks are less powerful in comparison to the main earthquake. Regardless of the term used to refer to the phenomenon, aftershocks are unpredictable in nature, and they can cause further damage to structures that have already been weakened by the initial earthquake.
