| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 0.35 | 0.920 | 100.0 |
| T < 1 s | 0.20 | 0.281 | 16.8 |
| T > 1 s | 0.65 | 3.8 | 83.3 |
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.
