| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.90 | 0.204 | 100.0 |
| T < 1 s | 2.78 | 0.211 | 91.6 |
| T > 1 s | 0.65 | 2.4 | 8.3 |
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.
