GEOLOGY

Detailed explanation-1: -In earthquake: Aftershocks, foreshocks, and swarms. …series of earthquakes are called earthquake swarms. Earthquakes associated with volcanic activity often occur in swarms, though swarms also have been observed in many nonvolcanic regions.

Detailed explanation-2: -A swarm, on the other hand, is a sequence of mostly small earthquakes with no identifiable mainshock. Swarms are usually short-lived, but they can continue for days, weeks, or sometimes even months. They often recur at the same locations. Most swarms are associated with geothermal activity.

Detailed explanation-3: -An Earthquake swarm is a sequence of mostly small earthquakes with no identifiable mainshock. Swarms can last weeks and produce many thousands of earthquakes within a relatively small volume.

Detailed explanation-4: -Some swarms are driven by slow fault slip that causes earthquakes on few sticky patches of the fault. Other swarms are generated when magma-filled cracks push their way through the crust.

Detailed explanation-5: -An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth’s lithosphere that creates seismic waves.
