But, are aftershocks also earthquakes? How common are aftershocks? LiveMint brings you a detailed coverage.
What is an aftershock?
Aftershocks are themselves earthquakes, but they are more accurately described as the lower-magnitude (or lower-intensity) tremors that follow the principal earthquake
According to Britannica, when an earthquake occurs, some of the energy released from the sudden fracturing of rocks is transferred to nearby rocks, which leads to additional stresses like pushing, pulling, and twisting. When these stresses become massive for the rocks to withstand, they break as well, releasing more pent-up energy and creating new faults.

The whole process of pulling and twisting causes earthquakes to trigger aftershocks, which in turn leads to multiple, yet small aftershocks.
Are aftershocks more severe than earthquakes?
Aftershocks tend to be the most severe and happen more frequently in the hours and days that follow an earthquake, stated Britannica.
Experts have advised that aftershocks are common in the immediate aftermath of an earthquake, typically within the first two hours.
Citing statistical data, Nation Thailand indicated the risk of a further significant earthquake, due to the aftershocks, within the next 24 hours.
