| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 17.13 | 0.426 | 100.0 |
| T < 1 s | 16.07 | 0.416 | 96.0 |
| T > 1 s | 3.10 | 1.6 | 3.9 |
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.
