| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.42 | 0.434 | 100.0 |
| T < 1 s | 2.17 | 0.336 | 82.1 |
| T > 1 s | 0.96 | 3.1 | 17.9 |
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.
