Aftershocks typically occur at a lower magnitude than the main earthquake and can vary widely in terms of their speed and intensity. The seismic waves generated by aftershocks travel at speeds similar to those of primary and secondary waves from the main quake, which can range from about 3 to 8 kilometers per second (approximately 1.9 to 5 miles per second) in the Earth's crust. However, the perception of aftershocks can vary; while they may occur immediately after the main quake, their intensity and frequency generally diminish over time.
