(geology) Anisotropy in the propagation of earthquake waves in the direction of rupture.

Sense（3）

(rare) Directionality

For higher degrees, the spatial integration tends to produce a cancellation and a rapid loss of visibility, although less rapidly for velocity measurement than for luminosity measurement, on account of the directivity of the velocity vector.
