| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 37.68 | 0.271 | 100.0 |
| T < 1 s | 35.73 | 0.267 | 99.2 |
| T > 1 s | 3.03 | 1.8 | 0.8 |
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.
