| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.99 | 0.475 | 100.0 |
| T < 1 s | 3.69 | 0.469 | 91.7 |
| T > 1 s | 1.22 | 1.8 | 8.4 |
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.
