Here is a site that shows where the 8 earthquakes today (so far) have occurred.

At the upper right of the page you can adjust the date to today (Nov 22) and press play. When it is done you can scroll over the list and see a visual representation of the quake magnitude and depth (shallow is generally worse).
The list of dates actually starts at March 11 2011 (the big Tohoku quake that spawned the Fukushima tsunami).
