| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 1.40 | 0.534 | 100.0 |
| T < 1 s | 0.93 | 0.190 | 29.3 |
| T > 1 s | 1.35 | 3.1 | 70.3 |
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.
