| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.37 | 0.502 | 100.0 |
| T < 1 s | 2.73 | 0.337 | 73.3 |
| T > 1 s | 1.67 | 2.2 | 26.8 |
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.
