| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 5.19 | 0.291 | 100.0 |
| T < 1 s | 5.17 | 0.296 | 95.0 |
| T > 1 s | 1.04 | 2.2 | 4.9 |
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.
