| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 7.50 | 0.370 | 100.0 |
| T < 1 s | 5.49 | 0.175 | 65.6 |
| T > 1 s | 2.87 | 3.1 | 34.4 |
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.
