Detailed distribution of the aftershocks of the October 06, 2017 earthquake. a The map indicates the profiles of the cross sections from A–A’ to I–I’ in panel (c). Horizontal intervals between the profiles are 2.5 km. The hypocenter of the mainshock is indicated by the red star on the profile E–E’. The aftershocks within 1 h after the mainshock are color-coded with time after the mainshock as shown in the magnitude-time diagram of panel (b). Other earthquakes are indicated with open circles. b Magnitude-time diagram of 1-h aftershock. c Cross sections along the profile A–A’ to I–I’ on panel (a). The aftershocks within 1 h after the mainshock are indicated by circles color-coded with the time after the mainshock. Earthquakes within the dotted rectangles are indicated on each cross section. Arrows indicate the dipping planes of the aftershocks
