The map on the left shows the seismicity after the Mw=6.2 (Mjma 6.5) mainshock until just before the Mw=7.1 (Mjma 7.3) mainshock. The future Mw=7.1 mainshock struck in an area of intensive aftershocks of the first mainshock. After the larger shock, the aftershock zone expanded to the southwest and to the northwest.
