Strike refers to the line formed by the intersection of a horizontal plane and an inclined surface. This line is called a strike line, and the direction the line points in (either direction, as a line points in two opposite directions) is the strike angle.

The dip of the inclined layer represents the direction the layer or bed is tilting into the Earth . The direction of dip would be the direction a ball would roll if set on the layer and released.  In Figure 3, the layers are dipping to the SE.  In this case, the dip is labelled “27 degrees,” so we know it is tilted exactly 27 degrees into the Earth.  Sometimes dip angles are not labeled, but we can still determine the dip direction (but not the magnitude) from the dip symbol.

Designed for clear communication in critical situations, the ‘Emergency Stop’ sign is essential for facilities that operate machinery with emergency stop mechanisms. Suitable applications include industrial plants, construction sites, and workshops where machinery can be quickly ceased in case of an emergency. Next Day Safety prints these signs to order, typically on the same day, ensuring prompt delivery across Australia. In compliance with Australian workplace regulations, this sign helps maintain safety standards by indicating the emergency stop control points. For further queries or information, please contact Next Day Safety. More safety sign options can be browsed at our safety signs category.

Dip is the angle between that horizontal plane and the inclined surface (such as a geological contact between tilted layers) measured perpendicular to the strike line down to the inclined surface.

Strike and dip map symbols look like the capital letter T, with a short trunk and extra-wide top line. The short trunk represents the dip and the top line represents the strike. Dip is the angle that a bed or layer plunges into the Earth from the horizontal. A number next to the symbol represents dip angle.

In Figure 3, the strike is measured as either 37 degrees, or 37 + 180 = 217 degrees.  Convention is to use the smallest angle (in this case, 37 degrees), but either is correct.

The strike indicates the azimuth (orientation) of the beds on the map – see the section on Azimuth for a description of how this is plotted.

Geologists measure the orientation (strike) and steepness (dip angle) of tilted beds of rock at an outcrop (Figure 2).  The direction and angle the beds are inclined will vary from location to location, so the location of each outcrop must also be recorded.

A useful way to think about strike and dip is to look at the roof of a house (Figure 1). A house’s roof has a ridge along the top, and then sides that slope away from the ridge. The ridge is like a strike line, and the angle that the roof tilts is the dip of the roof.

Tilted beds or layers occur when plate tectonic forces cause horizontal layers to be pushed up or dropped down unevenly.  This results in a tilting or incline of the original horizontal beds.
