Aftershock sequences

Aftershock sequences are smaller earthquakes that occur after the main shock of a larger earthquake. The main earthquake disrupts the Earth's crust, creating stress that can lead to these smaller quakes as the area readjusts. Aftershocks can happen seconds, days, or even years after the main event, gradually decreasing in frequency and intensity over time. Understanding aftershocks is important for assessing ongoing risks to structures and communities affected by the initial earthquake. They remind us that the earth is dynamic, and that safety measures should account for potential aftershocks following a significant quake.
