Wednesday's aftershock is the latest in a series of shaking that has taken place since last Friday's quake. The USGS said more than 40 aftershocks have occurred since Friday with most being 2.0-magnitude or less.
So how long can the area expect to possibly feel additional aftershocks? The chance will still around for at least some time, experts say. In many cases, aftershocks can occur for at least a week after the initial earthquake, experts say. The USGS said there is a 21% probability of a magnitude 3.0 or higher aftershock in the first month after this particular earthquake and a 3% chance of a magnitude 4.0 or higher.
