"You can't predict aftershocks of course, but we have no reason to think there will be a quake larger than this morning," Torres said. As the aftershocks continue, Torres emphasized the importance of continuing to practice good safety.

According to the USGS, there's only a 4 percent chance of another earthquake equal or greater than magnitude 7.0.

The USGS said in its entire aftershock forecast:

Low (4%) probability of another earthquake equal or greater than magnitude 7.0

27% chance of a magnitude 6+ aftershock, and it is most likely that 0-3 of these will occur

78% chance of magnitude 5 or greater aftershocks, but likely no more than around 20 of these
