 Earthquake clusters, swarms, and sequences

Earthquake clusters, swarms, and sequences are terms used to describe specific patterns of seismic activity that occur in close temporal and spatial proximity.

The earthquakes within a cluster are usually closely spaced in both time and location, but they may not have a direct causal relationship with one another.
