Quakes and aftershocks inside 100 miles
Aftershocks can happen days, weeks and even years after the primary earthquake. These occasions will be of equal or bigger magnitude to the preliminary earthquake, and so they can proceed to have an effect on already broken areas.
When quakes and aftershocks occurred
