| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 4.47 | 0.234 | 100.0 |
| T < 1 s | 3.36 | 0.119 | 78.1 |
| T > 1 s | 1.74 | 2.4 | 21.9 |
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.
