| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 46.14 | 0.257 | 100.0 |
| T < 1 s | 44.60 | 0.243 | 96.3 |
| T > 1 s | 9.66 | 1.5 | 3.6 |
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.
