Table 2 Search range of the grid-search for fault modeling

From: Fault model of the 2012 doublet earthquake, near the up-dip end of the 2011 Tohoku-Oki earthquake, based on a near-field tsunami: implications for intraplate stress state

Reference point latitude [°N]37.77c37.6–38.1d

W1 [km]b10, 15, 20, ..., 40e10
W2 [km]b10, 15e10
Slip amount [m]bAdjusted so that the VR values become maximal
  1. aStrike, dip, rake angles, and reference point depth were fixed to the GCMT value
  2. bRectangular fault model with uniform slip is assumed. The fault length (L = L1 + L2) was assumed to be greater than the fault width (W = W1 + W2)
  3. cA point 2 km west of the GCMT centroid
  4. dHorizontal location of reference point was searched within the range of ± 30 km in the EW and NS direction from the centroid location of Lay et al. (2013) (37.82°N, 144.13°E), with increments of 5 km
  5. eIncrements for the fault length and width are 5 km
