| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.51 | 0.206 | 100.0 |
| T < 1 s | 2.04 | 0.132 | 65.5 |
| T > 1 s | 1.33 | 2.8 | 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.
