| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 29.83 | 0.702 | 100.0 |
| T < 1 s | 25.86 | 0.589 | 77.0 |
| T > 1 s | 14.30 | 1.8 | 23.0 |
Significant height and period are derived from a zero-crossing analysis of the wave signal after the arrival time of the p waves.
They are the averages of the highest third of the waves.
