| Sig. Height μm/s | Sig. Period s | % of Variance | |
|---|---|---|---|
| Raw | 3.71 | 0.300 | 100.0 |
| T < 1 s | 3.67 | 0.295 | 96.4 |
| T > 1 s | 0.66 | 2.2 | 3.5 |
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.
