Im not sure about everywhere, but the Christchurch earthquake that occurred in February was actually a very large aftershock from the earthquake that they had been hit with in September the previous year.

Im sure it last longer depending on the magnitude of the original quake, but its still all settling into place so could be at least a few days.

Honestly, they last until they’re done. Sometimes it’s just that day, sometimes they last several days or weeks. There isn’t a hard and fast rule though. It’s the unpredictable nature of our earth’s crust! You guys should be fine though 🙂

@Jeannine @ Small Chic: I’m from Richmond and I can’t believe we’ve had two more aftershocks. Neither Darling Husband nor I felt either of the aftershocks, which is odd.

So far I haven’t felt any aftershocks in B-more, but I was out in the car earlier.

It really depends on what is under the surface in your area.  Is it rock? clay? sand?

I’m in Fredericksburg and my fiance and I definitely felt the aftershock right around 8pm last night, but we haven’t felt any since. I hope we don’t get any more today.

In the ’94 earthquake in SoCal, they lasted forever.  In fact for a month the ground just never stopped moving!

I heard they can happen anywhere from 2 hours after a quake up to 24. You might feel them for a while. Stay safe! We felt it up here in PA yesterday, what a feeling!

Honestly, there is no way to tell how long they’ll last.  Sometimes it is just that day, sometimes it is for months or more!
