Answer 1

Short answer: Yes, but the odds are small.

The USGS page that you linked to also links to a forecast: "According to our forecast, over the next 1 Week there is a 1 % chance of one or more aftershocks that are larger than magnitude 5.7."

USGS also notes:

No one can predict the exact time or place of any earthquake, including aftershocks. Our earthquake forecasts give us an understanding of the chances of having more earthquakes within a given time period in the affected area. We calculate this earthquake forecast using a statistical analysis based on past earthquakes.
