Figure 7. Quality factor Qp (dotted lines and gray bars),
Qs (thin lines and black bars), and geometrical spreading
n versus frequency for distance from 10 to 38 km (left frames) and
from 60 to 80 km (right frames). The mean ±2
are shown.
For P waves, the results for frequencies smaller than 2 Hz (gray shaded
area) are not reliable due to the low signal-to-noise ratio. In the left panel,
results of fit (thick lines for QS and gray lines for
QP) are shown.
