| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 101.76 | 0.476 | 100.0 |
| T < 1 s | 99.60 | 0.472 | 97.8 |
| T > 1 s | 13.68 | 1.7 | 2.2 |
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.
