| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 0.96 | 0.307 | 100.0 |
| T < 1 s | 0.80 | 0.160 | 57.4 |
| T > 1 s | 0.69 | 3.4 | 42.6 |
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.
