上地壳和上地幔剪切波固有品质因子Q_μ的区域性交化是显著的,在古老而稳固的克拉通中的值比构造活动区中的值在两个深度范围都大一个或一个以上的量级。Q_μ依赖于频率,至少在1Hz附近是如此,而这种频率相关在上地壳也有区域性变化。它在构造活动区较低而在稳定区较高。由于Q_μ在各地区有大的变化,对上地壳的Q_μ和由Lg尾波(Q_(Lg)~c)估计得到的Q绘制区域性交化图是容易做到的,尽管这两种方法都可能有很大的不确定性。虽然直达体波的尾波Q可能被散射严重地影响,但Q_(Lg)~c好象主要是由上地壳的固有Q_μ决定的。上地壳Q_μ和Q_(Lg)~c的值都与大陆区最新的构造活动以来所经历的时间有关。
The regional intercalary of the intrinsic quality factor Q_μ of shear waves in the upper crust and the upper mantle is significant, with values in ancient and stable carats being one or more magnitudes greater in both depth ranges than in the tectonic activity zone level. Q_μ depends on the frequency, at least around 1 Hz, and this frequency dependence also has a regional change in the upper crust. It is lower in the tectonic activity area and higher in the stable area. Since Q_μ has a large variation in all regions, it is easy to plot the regional Q_μ of the upper crust and the Q estimated from the Lg coda (Q_ (Lg) ~c), although both methods are possible There is a lot of uncertainty. Although the coda wave Q of direct body waves may be seriously affected by scattering, Q_ (Lg) ~ c seems to be mainly determined by the intrinsic Q_μ of the upper crust. The values of Q_μ and Q_ (Lg) ~ c in the upper crust are all related to the time elapsed since the latest tectonic activity in the continental zone.
