In all likelihood, the USGS says there is 80% chance that the earthquakes will continue, but will decrease and none of them will exceed a magnitude-5.4 within the next seven days. However, there is also a 19% chance of a bigger earthquake, between a 5.5 or 6.9, and in the least likely scenario, there is a 1% chance of a magnitude-7.0 or higher earthquake within the next seven days.
