Stress Block & Seismic
The Stress Block & Seismic option in the View menu toggles the display of the "stress block" and the "seismic icon" in the upper right corner of the view.
Stress Block
The Stress Block indicates the relative magnitude and direction of the IN-PLANE principal field stresses.
Stress Block (Sigma1 = 1.5*Sigma3, Sigma1 angle = 30 degrees from horizontal)
Seismic Icon
When (non-zero) seismic coefficients have been defined (in the Seismic Loading dialog), a Seismic Load icon will be displayed in the upper right corner of the view (below the Stress Block). The icon indicates that seismic load has been applied to the model, and the magnitude and direction of the seismic coefficient(s).
Seismic load icon (horizontal coefficient = 0.2, vertical coefficient = -0.1)
NOTE: if you have used the Applied in Stage option to define the stage at which the seismic load is applied, then the seismic icon will only appear at the specified stage (and all subsequent stages). It will not be displayed for stages prior to the stage of application.
Right Click Shortcut
In the RS2 Interpret program, the display of the Stress Block / Seismic icon can be turned off by right-clicking on the icon and selecting the Hide option. To turn the display back on again, you will have to use the Stress Block & Seismic option in the View menu.
