Figure 5 . (a) : Seismicity in a distance of 5 km of the
MSH from 1996 until the M5.1 mainshock. Circles and hexagons are the
earthquakes from 1996 to the end of 2005, and 2006 until before the
M5.1, respectively. Dotted, solid, and dashed lines are Western,
Central, and Eastern segments of the MSH, respectively. (b) :
Histogram showing the distribution of earthquakes along the MSH.(c) : Distribution of scalar seismic moments along the MSH from
2006 until before the 2020 M5.1 mainshock. (d) : Distribution of
scalar seismic moments along MSH from 2006 until 22 June 2020, including
the M5.1 mainshock and 27 M>=2.5 early aftershocks.
