Table 5 Decomposition of non-DC MT of the M _JMA6.5 foreshock from 2016/4/14 21:26:35 JST (event No. 1) and the decomposition by Eqs. (13) and (14) preserving MT T-axis

	Mechanism	S/D/R (°)	DC component (%)	M ₀ (Nm)	\( \frac{{M_{0} }}{{M_{0}^{\text{sum}} }} \cdot 100\%\, (\%) \)
Original non-DC MT	Strike-slip	33/82/−155	64	1.84 * 1e+18	100
MT_major	Strike-slip	33/82/−155	100	1.51 * 1e+18	82
MT_minor	Normal	93/60/−63	100	0.33 * 1e+18	18
MT_sum	Strike-slip	33/82/−155	64	1.84 * 1e+18	100

The original non-DC solution is listed with decomposed DC major and minor MTs and their sum \( {\mathbf{MT}}_{{{\mathbf{major}}}} + {\mathbf{MT}}_{{{\mathbf{minor}}}} = {\mathbf{MT}}_{{{\mathbf{sum}}}} \); S/D/R strike/dip/rake
