What are aftershocks?
Aftershocks are smaller earthquakes in the same general area after a larger mainshock. They may continue for days to years. Two dots close together on a map are not enough to prove that relationship.
A sequence is identified from evidence
The description depends on timing, location and the developing sequence. An event is called a foreshock only after a larger earthquake follows in the area. An apparently isolated event cannot be labelled a foreshock in advance just because it has happened.
Use nearby events as context
QuakeMap Live links geographically or historically related records without automatically calling them aftershocks. An empty list is not an all-clear, and a cluster is not a prediction. For an official sequence assessment or aftershock forecast, consult the responsible seismic agency and follow local safety instructions.
