| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 73.55 | 0.266 | 100.0 |
| T < 1 s | 73.13 | 0.278 | 99.9 |

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.
