Fig. 3.

Spatial distribution of background seismicity. (a) Filled circles denote events larger than Mj 6 which occurred from 1967 to 2010 (see inset for magnitudes and origin times, respectively, depicted by sizes and colors). Open red circles denote seismicity in the current fore-shock-mainshock sequence. Gray dots denote the seismicities of the background in the time and depth ranges of January 2000—September 2010 and 1–50 km, respectively. Blue stars denote epicenters of the current foreshock and mainshock, and the 2005, Mj 6.3, event as indicated in (b). (b) Green dots denote seismicity activated in August 2005. (c) Space-time plot of seismic sequence of 1981 along the rectangular cross-section C–C′ shown in (a).
