| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 2.42 | 0.363 | 100.0 |
| T < 1 s | 2.02 | 0.302 | 65.7 |
| T > 1 s | 1.14 | 2.2 | 34.2 |
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.
