| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.22 | 0.228 | 100.0 |
| T < 1 s | 2.91 | 0.208 | 88.0 |
| T > 1 s | 1.09 | 2.0 | 12.0 |
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.
