The horizontal stress due to the tectonic movements, can be estimated using the ratio of the average horizontal stress to the vertical stress, as shown below:
The horizontal stress due to the tectonic movements, can be estimated using the ratio of the average horizontal stress to the vertical stress, as shown below:
<math>\sigma_h = k \sigma_v = k \gamma z</math>
where is the unit weight of the overlaying rock [mN/ m3].
where γ is the unit weight of the overlaying rock [mN/ m<sup>3</sup>].
::z is the depth to point below surface [m].
::z is the depth to point below surface [m].
::k is the ratio of the average horizontal stress to the vertical stress.
::k is the ratio of the average horizontal stress to the vertical stress.
