Aftershocks locations and time distribution
The aftershock activity is unusually high. Generally, the largest aftershock is about one unit less in magnitude, so M5-5.2 in this case. The figure shows that on 20/08 at 11:00 UTC we have 5 earthquakes reaching this value, and 4 of them clearly above the maximum expected magnitude in a usual mainshock-aftershock pattern.
There is no clear conclusion to draw from this unusual pattern, and further earthquakes of similar magnitude cannot be excluded.
