| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.81 | 0.180 | 100.0 |
| T < 1 s | 1.57 | 0.137 | 75.4 |
| T > 1 s | 0.79 | 2.7 | 24.7 |
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.
