| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.45 | 0.399 | 100.0 |
| T < 1 s | 1.18 | 0.228 | 52.3 |
| T > 1 s | 1.07 | 3.8 | 47.6 |
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.
