| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.10 | 0.273 | 100.0 |
| T < 1 s | 0.91 | 0.170 | 53.4 |
| T > 1 s | 0.89 | 2.5 | 46.5 |
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.
