| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.06 | 0.434 | 100.0 |
| T < 1 s | 0.94 | 0.301 | 62.6 |
| T > 1 s | 0.70 | 3.1 | 37.4 |
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.
