Aftershocks are smaller tremors that follow a major earthquake. They occur as the Earth's crust adjusts to the changes caused by the initial earthquake. Aftershocks can be almost as powerful as the main earthquake and may continue for days, weeks, or even months after the initial event.
These aftershocks can further damage already weakened structures, disrupt rescue and recovery efforts, and create additional fear and uncertainty among people already affected by the initial earthquake. It is essential for emergency preparedness and response plans to take into account the potential impact of aftershocks on the affected area.
